1. Chair’s Remarks and Announcements- J Ed Smith The Chair pointed out that this is his last meeting as the Chair and that Bill Chiu will take over in January. Ed thanked everyone for their assistance during his tenure. The Chair announced that Steve Antosz will be new Secretary starting January 1, 2012. The Chair also announced that we will have 2 new Subcommittee Chairs. Ed teNyenhuis will take over the Performance Characteristics Subcommittee. Richard Dudley has resigned as the Chair of the HVDC Converter Transformers & Smoothing Reactors Subcommittee. He will be replaced by Mike Sharp. At this meeting, we added a Patent Disclosure area on the Registration form. This allows anyone to disclose any patents in advance, so that we will not hinder the WG chairs with this responsibility. We did get several responses of potential patent claims. Comments on Reorganization of the Schedule for our Sunday to Thursday meetings. We plan to make changes to the Main meeting and establish an Awards lunch format starting in Nashville. The main committee meeting (General Meeting) will be split into two parts. The General Committee meeting will be held during the 8 AM time slot on Monday morning. We will cover the new items from the Administrative Subcommittee, and New Business. We will also allow time for each Subcommittee Chair to present a quick coming attractions type report. We will move the tutorials to Thursday morning. Then following the tutorials we will add a follow-up meeting of the Committee. During this time, we will have a simplified version of the Subcommittee reports. We have meetings of non-core activities that occur during our week of meetings. The officers have agreed that we should move these non-core group meetings outside of the Monday to Thursday core meeting time. We expect the NEMA meeting to remain, and move the IEC TC14 and EL&P delegation meetings.

3.4.4 Conference Paper Review Criteria

In the PESGM 2011 Technical Council meeting in Detroit, we expressed concerns on the quality of the papers being submitted. Many other technical committees also expressed similar concerns. Currently the acceptance criteria do not address some of the concerns such as repeat of information already published previously with a mere change to present the information in a different structure or format. In some cases the papers are submitted by authors from non-English speaking countries and there are significant challenges with grammar and editorial edits. An extract of the existing highlights are listed below in blue text.

Acceptance or Rejection

Proceedings papers are published as part of the Conference Proceedings of the PES General Meeting where the paper is presented. In addition to meeting the criteria outlined above, a Proceedings paper will only be accepted for the meeting if it:

is submitted in keeping with the published schedules

is submitted in the required formats with the required paperwork

addresses the topic in an appropriate manner

is of a technical rather than commercial nature

is more than simply a restatement of well-known technology

is judged to exceed a qualitative criterion of being elementary or trivial in its presentation

does not exceed the eight-page limit.

The TCPCs have agreed to review and revise the guideline to develop a new draft to address the concerns shared. I will be representing the Transformers Committee in developing this new guideline so I welcome suggestions on how to best handle some of the issues we have encountered in the past.

3.4.5 Existing Review Guideline for Transaction Papers

Text from the existing established guideline is included below for reference. The same information can be found on the PES website at: http://www.ieee-pes.org/part-8-reviewer-and-editor-guidelines

Two membership applications (Brender and Locarno) were returned as the applicants were not listed as members of the working groups that signed to sponsor them. The se applicants were encouraged to speak to the working group chairs to ensure they were documented members, and then to resubmit the applications.

The Transformers Committee currently has three general categories of p articipation in our activities. These are: Interested Individual, Active Participant, and Committee Member. Any one can join our AMS 1 23 system as the system is de signed for self-registration. A new participant will automatically be assigned the role of Interested Individual when they first sign up. Based on the level of participation, the co mmittee administrative staff will upgrade the participation status to “A ctive Participant” when appropriate. The Com mittee Member status however, can only be attained thro ugh a formal application with the sponsorship of minimum of three WG or SC chairmanships. Detail of the application requirements and approval process by the Administrative Subcommittee is outlined in our O&P manual.

The following table contains a recent count of the participants grouped by the three general categories.

will be collected for review and approval i n batches at each Administrative Subcommittee meeting. For an appli cation to be revie wed at the next meeting, the appli cation will need to be received by the Committee Secretary a minimum of one week prior to th e start of the tha t meeting.

3.5.3 Committee, Subcommittees, and Working Group Rosters In order to provide indemnification to working group and subcommittee members it is crucial that membership lists be m aintained. Our AM system has the se functions built-in to ea se these administration tasks. It is importa nt that each subcommittee and working group chair keep the rosters updated so that this information can be provided to the IEEE SA.

A similar ma in committee roster has also been developed to track attenda nce for the Main Committee meeting on Thursdays. The data will be used to update participant’s membership profile.

3.5.4 Meeting Minutes The minutes of the San Diego, CA Spring, 2012 Transformers Committee meeting were posted to the committee website on September 16, 2011.

Subcommittee Chairs are requested to submit their SC Minutes from the Boston, MA meeting by December 15, 2011.

The minutes should be submitted via e-mail to the Committee Secretary at [[email protected]], with a copy to Susan McNelly [[email protected]] for posting on the Committee website.

The submittal file should be saved as a Word document and should be formatted similar to this report, and as shown in the recent assembled Minutes. The numbering for your report should match the numbering as indicated in the Main Committee Meeting Agenda. Please indicate total attendance count for each Subcommittee, Working Group, and Task Force meeting in your Minutes. Please do not send a copy of the attendance listing for this attendance count.

3.9 Standards Report – B. Bartley Bill Bartley discussed the highlights of the draft report of standards activities since the October, 2010 Meeting (San Diego, ON). Erin Spiewak is our new program manager for Transformers Committee activities. Contact info: [email protected] 732-465-7806. Major changes in IEEE Ballot Procedure have been approved by Standards Board of Governors for implementation Jan 2012. Reaffirmation and Stabilization options will be eliminated. Starting in 2012 every standard will have a 10 year life, not 5. All of them must be revised at least every 10 years. A key concern is the IEEE risk that develops when comments are not addressed in a reaffirmation ballot. Or the ballot resolution group simply dismisses comments on technical flaws by stating “reaffirmation doesn’t allow changes”. Subcommittee Chairs were asked to review Standards Database to ensure that the information provided is correct. Presently have approximately 101 documents, and 51 active PARS. Further details of the standards activities are listed in the Standards Report and it is included in the minutes of the Committee meeting, Appendix C - Transformer Standards Development Status and Transformer Committee Organizational Chart. 1 new standard has been approved. 3 document revisions have been approved. The Standards Board submission dates:

The former need has been addressed by the publication of C57.12.36. The Subcommittee chairs have been asked to look for the impacts of eliminating this distinction. Lightning impulse and induced test requirements are the primary issues that are affected. This has been voted on by the Dielectric test Subcommittee several times. To be reviewed at Standards SC meeting as the definitions are in C57.12.00. 13.1. If Discussion of Essential Patent Claims comes up this week-- Refer to Platts for resolution.

14. Adjourn 5:17 PM

1.0 Chair’s Report IEEE PES Transformers Committee Spring 2011, San Diego Meeting

1.1 Transformers Committee Highlights 1.1.1 As everyone has noticed during your registration process for our Boston meeting, the

Patent Disclosure requirement is now a permanent part of our registration process. We’ve made it part of both the “on-line” and “hard copy” registration. This new process change will allow us to significantly improve our IEEE-SA patent disclosure responsibilities. The new process allows us to make the overall patent disclosure process part of the individual’s permanent registration record. It also eliminates the requirement for Task Force, Working Group and Subcommittee chairs making a request for patent disclosure claims at the beginning of each of their meetings. The new process will be stated as follows:

NOTE: All participants in this meeting have certain obligations under the IEEE-SA Patent Policy (See the Transformers Committee’s website for additional information, refer to the IEEE Patent Policy “section”). Participants shall inform the IEEE of the identity of each “holder of any potential Essential Patent Claims of which they are personally aware” if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents. “Personal awareness” means that the participant “is personally aware that the holder may have a potential Essential Patent Claim” even if the participant is not personally aware of the specific patents or patent claims If anyone registering for this meeting is personally aware of the holder of any patent claims that are potentially essential to the implementation of any of the proposed standard(s) under consideration by any task Force, Working Group or Subcommittee that they will be participating in and that are not already the subject of an “Accepted Letter of Assurance” they are encouraged to disclose that information.

NO, I am not aware of any potential Essential Patent Claims

YES, I am aware of any potential Essential Patent Claims (if YES describe in detail below)

(If you answered YES you will possibly be contacted by the Transformers Committee Secretary for additional information)

(Describe in detail and as a minimum, list the WG and/or SC that are affected, the affected document, the Essential Patent Claim, the Company and/or individual patent holder) __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________

In conjunction with the new registration process, we are dedicating a section of our web site to Patent Disclosure information. A specific description of the requirement along with a link to the IEEE-SA web site that further defines the specific requirement will be provided. Also a link to the latest revision of the IEEE-SA’s slide presentation is provided as an additional reference tool.

1.1.2 Another tool we are in the process of implementing since our San Diego meeting . . . .

To help navigate through the IEEE-SA MyBallot process a little easier we have dedicated a section of our web site to providing a library of web links that should help simplify the process.

Several of you have expressed difficulty in remembering now to access various sections of the MyBallot process due to the infrequency of use. We made a decision to establish a library of “short cuts” to expedite navigating the MyBallot Process. We will be adding additional links to the library as we receive feedback from you as you access and use the feature.

1.2.1 I was unable to attend the 2011 PES General Meeting due to personal issues.

Therefore, I asked both Bill Chiu, Vice Chair and Don Platts, Secretary to represent the Transformers Committee Chair at the Technical Council meetings and make notes for inclusion in this Chair’s report. Listed below are the unedited notes that were made.

1.2.2 Bill Chiu: Here are the few highlights from the PES GM in Detroit that could be of

interest to our membership. 1.2.2.1 Elimination of the reaffirmation process. (I believe Bill Bartley

will go over these in detail) 1.2.2.2 Elimination of the "Interpretation" of standards. IEEE will no longer offer Interpretations through the technical committees. This was voted on and approved at the June, 2011 IEEE SA Board meeting. (I believe Bill Bartley will also go over these in detail as well) 1.2.2.3 Seeking volunteers for the Fellow's nomination process. Coordinator needs to be a Fellow, but can not nominate, nor second a nomination. The coordinator also can not serve as the source for letter of reference.

1.2.2.4 The other items on the quality of paper presented and a proposal to revise the acceptance criteria will be included in my report.

1.2.2.5 I've also attached the draft meeting minutes from the Tech Council meeting, but I just realized they didn't include a lot of the details (see “Attachment A”).

1.2.3 Don Platts: During the PES Opening Session a call for nominations for IEEE Fellows. Also, it was noted that many of the available awards were not presented to anyone because of a lack of nominations.

1.2.3.1 Technical Council O&P Committee: Aud Com rejected 3 new O&P manuals in July 2010. They were based on the Transformers Committees manual. Aud Com wants to remove all items that are not related to standards development. So each committee will need 2 documents, one for standards, and another for all other information.

The P&P, Policy and Procedures will be just Standards Development. Contents: membership, and officers; the organizations – Subcommittees; and the procedures for Standards Development. The procedures for other activities will not be in there. That goes into the O&P.

The deadline to get an approved P&P is December 2012. The P&P document will be posted on the SA webpage.

Motion made and voted approved -each committee shall revise their documents and get

their P&P to Manni (Chair of O&P comm.) Aud Comm mtg Submit by Dec 11 Oct 11 Mar 12 Dec 11

Working Group Policy and Procedure Should everyone work from a default procedure, or should each WG develop a specific document that must be approved by the Adcom of each technical committee? A group consisting of Lisa Yacomb, Bill Barley, Ted Olson, and Jeff Nelson (?) will draft a ‘fill in the blanks’ form as a start of the P&P. They will submit the draft to the technical committees for review and comment.

Each committee is requested to update their O&P manual and submit to Manni for review and ballot by Technical Council O&P Comm. by July 2012.

1.2.3.2 Technical Sessions Committee: Comments: “Supersessions” need to be organized faster. Too many tutorials, they conflict with the working group meetings. They also have too many conflicts between similar working groups, (particularly in the wind power area).

May decide to combine the PSCE with the Smart Grid conferences. Attendance has not been good.

TCPC and the O&P comm will meet in January in Anaheim. The JTCM is Jan 8 – 12th.

The 2012 T&D conference will have poster sessions and some panel sessions, but no paper sessions. The call for papers was out with a deadline of Aug. 8, 2011.

The next General Meeting will be in San Diego. By the January JTCM, all panel session information should be ready. The schedule spreadsheet layout of this year’s meeting will be used again, with a default number of rooms for each comm. [So transformers should get 3 again]. Then based on the number of papers each group has, the schedule will be finalized at JTCM.

They noted that they need supersession chairs, and tutorials, the due date would be very soon. (Summer of 2011). Meeting Agenda: (See “Attachment B”)

1.2.3.3 Meetings and Marketing: Pat Ryan and Al Rotz attended to sell the merits of the PES Resources Center. The objective is to get the efforts of our work out to the world. When we donate our tutorials, or other information, we can restrict who can view it. Anyone / IEEE members / or only PES members. They noted that the transformers committee has agreed to offer our tutorials sessions.

If we want them to post something, we must provide a paper abstract and list of keywords. Since it is the transformers committee that is ‘giving‘ the information, PES assumes that it has been reviewed and approved by the committee.

It was noted that other technical committees may want to use the AMS system from 123 that the transformers committee is already using. The hope is that it will eliminate some work for the smaller committees and may reduce the overall costs to each committee.

It was noted that the IEEE Press has several older books that are available in e format, that are free of charge. Also 40-50 old tutorials are also now available. Meeting Minutes: (See “Attachment A”)

1.2.3.4 Technical Council Meeting: Bill Chiu, Bill Bartley, and Tom Prevost also attended this meeting. By this Wednesday PM, the jet lag from my trip to Korea had kicked in. But my notes follow:

PES Policy Development -suggestions are due by 10/15/11

For each of the technical committee meetings, we should contact Malia Salet so that she can contact the local chapters to inform them of the opportunity to attend.

Bill Rosehart (IEEE PES involved with the foreign PES conferences) wants a technical reviewof all papers that are presented at these foreign conferences. That would establish a tie between the technical committees and these conferences. Now the local host arranges for paper reviewers. This was not well received, but no action was taken.

Switchgear website page for future meetings shows the new PES template. I think the intent was that all committees would have a similar appearance to their websites.

As we have already been warned and informed, in June, SA voted to eliminate reaffirmations, effective Jan 2012. Standards will have a 10 yr. life, and the only options we may choose from are to revise, amend/ issue corrigendum, or withdraw. They have also eliminated the opportunity for someone to request an interpretation. As we know the deadline for submissions for any reaffirmations (or other standards submissions) is Oct 17, 2011.

A request was issued for volunteers for the Standards Board.

4.4 Conference Paper Review Criteria

In the PESGM 2011 Technical Council meeting in Detroit, we expressed concerns on the quality of the papers being submitted. Many other technical committees also expressed similar concerns. Currently the acceptance criteria do not address some of the concerns such as repeat of information already published previously with a mere change to present the information in a different structure or format. In some cases the papers are submitted by authors from non-English speaking countries and there are significant challenges with grammar and editorial edits. An extract of the existing highlights are listed below in blue text.

Acceptance or Rejection

Proceedings papers are published as part of the Conference Proceedings of the PES General Meeting where the paper is presented. In addition to meeting the criteria outlined above, a Proceedings paper will only be accepted for the meeting if it:

is submitted in keeping with the published schedules

is submitted in the required formats with the required paperwork

addresses the topic in an appropriate manner

is of a technical rather than commercial nature

is more than simply a restatement of well-known technology

is judged to exceed a qualitative criterion of being elementary or trivial in its presentation

does not exceed the eight-page limit.

The TCPCs have agreed to review and revise the guideline to develop a new draft to address the concerns shared. I will be representing the Transformers Committee in developing this new guideline so I welcome suggestions on how to best handle some of the issues we have encountered in the past.

4.5 Existing Review Guideline for Transaction Papers

Two membership applications were returned as the applicants were not li sted as members of the working groups that signed to sponsor them. These applicants were encouraged to speak to the working group chairs to ensure they were documented members, and then to resubmit the applications.

The Transformers Committee currently has three general categories of pa rticipation in o ur activities. These are: Interested Individual, Active Participant, and Committee Member. Any one can join our AMS 123 system as the system is designed for self-registration. A new participant will automatically be assigned the role of Interested Individual when they first sign up. Based on the level of participation, the committee administrative staff will upgrade the participation status to “Active Participant” when appropriate. The Committee Member status however, can only be attained through a formal application with the sponsorship of minimum of three WG o r SC chairmanships. Detail of th e application requirements and approval process by the Administrative Subcommittee is outlined in our O&P manual.

The following table contains a recent count of the participants grouped by the three general categories.

The Committee welcomes and encourages active participants to become Me mbers of the Committee. Requirements and application forms can be found in the Organization and Procedures (O&P) Manual, accessible on the Committee website. Sub committee Chairs are encouraged to recommend new members, and to communicate the process of attaining membership through active participation and contribution in Committee work at the WG and S C level. WG and SC Chairs are re minded also that signing an application sponsoring a new member signifies their sponsorship that the applicant has met the requirement of memb ership and active participation for at l east one year in the WG or SC they

Chair. New member applications may be submitted to the Committee Secretary’s attention at any time. Applications will be collected for review and approval in batches at each Administrative Subcommittee meeting. For an application to be reviewed at the next meeting, the application will need to be received by the Committee Secretary a minimum of one week prior to the start of the that meeting.

5.3 Committee, Subcommittees, and Working Group Rosters In order to provide indemnification to working group and subcommittee members it is cruci al that membership lists be main tained. Our AM system has the se functions built-in to ease these administration tasks. It is impo rtant that each subcommittee and working group chair keep the rosters updated so that this information can be provided to the IEEE SA.

A similar main committee roster has also been developed to track attendance for the Main Committee meeting on Thursdays. The data will be used to update participant’s membership profile.

5.4 Meeting Minutes The minutes of the San Diego CA Spring, 2012 Transformers Committee meeting were posted to the committee website on September 16, 2011.

Subcommittee Chairs are requested to submit their SC Minutes from the Boston, MA meeting by December 15, 2011.

The minutes should be submitted via e-mail to the Committee Secretary at [[email protected]], with a copy to Susan McNelly [[email protected]] for posting on the Committee website.

The submittal file should be saved as a Word document and should be formatted similar to this report, and as shown in the recent assembled Minutes. The numbering for your report should match the numbering as indicated in the Main Committee Meeting Agenda. Please indicate total attendance count for each Subcommittee, Working Group, and Task Force meeting in your Minutes. Please do not send a copy of the attendance listing for this attendance count.

Your full corporation and support in this matter is greatly appreciated.

Page 1 of 4

1. Opening Remarks The Chair, William Bartley opened the meeting and summarized the recent activities of the Transformer Standards activity for the seven-month period of April 2011 through October 2011, one new Standard, and three Revisions were approved by RevCom. Also, NesCom approved two PARs for new standards, four PARs for Revisions, four PAR modifications, but no PAR extensions. The Transformer Committee is responsible for almost 100 standards, plus over 55 PARs, projects for new standards and revisions. For the full STANDARDS REPORT see the TC website via the following link:

http://www.transformerscommittee.org/meetings/F2011_Boston/Minutes/F11-StandardsReport.pdf

An overview of the upcoming new 10 year maintenance cycle change presented at the Standards Luncheon was given. The change will extend the revision (reaffirmation) cycle from 5 years to 10 years after the last date of approval or maintenance action. The Chair stressed there would be no extensions. It is suggested to review the full presentation at:

http://www.transformerscommittee.org/info/F11/F11-IEEE-StndsPolicyChanges.pdf

2. Meeting Attendance

The Standards Subcommittee met on Wednesday, November 2, 2011, at 4:30 PM. A role call showed over 25 members in attendance constituting a quorum. Overall there were 106 attendees, with 29 members, with 77 guests, including 15 that requested membership upon tabulation of the circulated rosters.

(Postscript note for the 13 of the members that were unable to attend, and now have missed two or more, consecutive meetings, please expect to be changed to guest role prior to the S12 meeting).

3. Approval of previous meeting minutes The Chair asked if there were any comments or corrections to the previous meeting minutes, and motioned for approval. There where no comments to the meeting minutes of the Spring 2011 meeting in San Diego, California; and the minutes were approved.

4. Working group reports.

Cont. Revision of C57.12.00 – Steve Snyder reported the following:

This is essentially a working group of one person. There are no meetings.

The purpose of this WG is to keep track of, and compile, all the work being done in various TF/WG/SC’s for inclusion in the continuous revision of C57.12.00 in a consistent manner. This WG coordinates efforts with the companion Standard C57.12.90 so that they publish together. The goal is to issue new Standards every 2 to 3 years.

Standard C57.12.00 was published September 2010. A new PAR was requested in April and approved June 16, 2011 to cover the ongoing work for the continuous revisions. This PAR is good through December 31, 2015.

At present, I am aware of only a few minor items that are ready for the next revision cycle; however there are a couple tasks nearing completion in the PCS working group. Approximately mid-year 2012 I had planned to solicit input from all the Subcommittees to determine what material is ready for inclusion in the next revision cycle. If appropriate, a new revision will be launched near the end of 2012.

Respectfully submitted, by Steven L. Snyder, WG Chair, on November 2, 2011

Cont. Revision of C57.12.90-2006 – S. Antosz reported the status of as:

This is essentially a working group of one person. There are no meetings held. The purpose of the WG is to keep track of the work being done in various TF / WG / SC for inclusion in the continuous revision of C57.12.90 in a consistent manner.

One web meeting was held since the San Diego meeting and the following was discussed:

Proposed revised section on 6.3.11 Moisture in Oil and 6.3.12 Water Content (Oleg Roizman).The old and new versions were discussed, so the WG could see the proposed changes. The draft included numbers for, PPM and Relative Saturation, as well as Natural Ester Fluids. There was consensus that we should leave relative humidity out of the main document, and put something about it in an Annex. A task force, consisting of Oleg, Roizman, Jim Thompson, John Luksich, Claude Beauchmin, Maik Koch and Mario Locario, was set up to develop such an annex. While the proposed draft on moisture in oil and water content would not be immediately adopted, it is

foreseen that would be best the parent standard for moisture (C57.106) include the relative saturation specific values. If the annex is available it could be included at initial issue, or in a subsequent revision after the parent standard is issued. The subject of moisture has been an on going topic it is believed that publishing PC57.152 should not be restrained while an annex, or parent standard are developed.

Induced Voltage Testing section has been added to the Guide. It was agreed to add more footnotes about the testing and remove Table 1 or the chart of the transformer health conditions before performing the Induced Test. The Caution Note will be expanded to include more specific especially for transformers over 69 kV.

A new section on Applied Voltage Testing was reviewed. The WG agreed to add Applied Voltage Section before the Induced Test in the main body of the Guide as opposed to the Annex.

It was agreed to move away from IEEE 62 format / arrangement to proposed sequence of testing or at least focus on winding and tests related to the main core and coil then list by Bushings, LTC and Ancillary Equipment. The Chart for commissioning, in-service, after system fault and after internal fault was updated with a column added to reference the specific article of PC57.152. We will try to follow the order of the tests; but may need cautions, depending upon magnetization of the core, etc.

Discussed was held on Frequency Response Test and determined that the test should be Optional for Commissioning and AN (or As Needed) for other times. The Winding Resistance test should be REC (Recommended) for Commissioning. We added the Applied Voltage test and it is Opt for all cases. We will address reference to C57.93 for installation tests and PC57.125 for the tests after faults.

The Work Plan spreadsheet has been updated to show progress. All sections have been presented and reviewed. Reference section will be reviewed after the overall order of the document is revised. Gary Hoffman volunteered to help with this effort.

The document now comprises 35 sections which are authored by many different persons. The document will be reorganized to put Safety closer to the beginning and to flow more logically. Each section that has a parent standard will be sent to the Working Group Chairman for that Standard to review and insure that the proposed draft is in line with parent standard. A 60 day reply period will be given.

The PAR expires in December 2012. The WG hopes to finish basic comments and final edits with a ballot among the WG before Nashville. At least three months are expected to be allocated for ballot resolutions.

TASK FORCE on IEEE-IEC Harmonization – Jeewan Puri -

The TF Chair explained this was the final report as at the Paper on Harmonization of Standards with the IEC was presented. This paper provides an overview of the process for new technical standards, existing standards, items to consider, copyright permissions, Annex A of IEC Technical Committees and Annex B a sample copyright permission request letter. Everyone is encouraged to read the paper, and then apply its recommendations, as appropriate. The paper is available on Standards SC webpage.

The SC Chair thanked the TF Chair Jeewan Puri for coordinating the paper; and acknowledges the efforts by the IEEE’s Ms. Jodi Haasz, and Mr. Paul Jarman, Chairman of IEC Technical Committee 14 for their coordinated work in creating the paper.

TASK FORCE on Recommended Terminology for the use of Fluid, Oil, and Liquid across all the Transformer Standards, Guides and Best Practices – P. McShane

A brief presentation by Task Force Chair P. Mc Shane was given to explain the purpose of the review, and output report of a white paper describing the nomenclature uniformity issues, and identification of clauses that should considered including, or excluding, the various insulating mediums including alternative fluids.

The presentation is on the Standards Subcommittee webpage as given by P. McShane.

5. Old Business

At the spring meeting there was a proposal for new Task Force, presented by Dr. Valery Davydov to development new document called: Moisture in Insulating Systems of Gas Insulated & Liquid Immersed Transformers & Reactors. Due to limited time it was agreed to continue the topic at the fall meeting. Therefore, an updated presentation was given to the attendees, and a copy is on IEEE TC Standards SC webpage. Following several questions and discussions points regarding the merits, expertise needed, and the most appropriate Subcommittee that could liaison across several Subcommittees to handle the subject matter; it was motioned, and the motion amended to create and pursue a Task Force under the Insulation Life SC. The Standards SC members passed the motion with no opposing votes. Further actions and efforts will transfer to the oversight of the Insulation Life Subcommittee and it is noted that the Chair of Insulation Life (Bruce Forsythe) was present at the Std SC meeting, and was amenable to the transfer of this project to his SC.

6. New Business There was one request for new business was raised on an informational basis. As any action would impact several standards, guides, and multiple SCs; time was provided for a presentation and discussion to seek opinions from the Standards SC.

The presentation was made by Bill Chiu regarding the subject of whether the Class I and Class II designation for Power Transformers should be retained. The presentation is available on the Standards SC website. No motions were raised, as this was an informative presentation. If further action were to occur it would be under the Power Transformers Subcommittee.

7. Adjournment The motion to adjourn by Chair made and hearing no objections; the meeting adjourned around 5:35PM.

technical reports, or of standards and guides. Excerpting from the PES website

(http://www.ieee.org/portal/site/pes/) Awards pages:

“The PES Working Group Recognition Awards recognize “the most outstanding and timely

publications” by a PES Working Group (or Committee or Subcommittee) from among the

nominations. The PES Recognition Award is divided into two categories: 1) for technical

reports; 2) standards and guides. Each Technical Council Committee may nominate one report

from each category, published by IEEE, during the previous three year period.” This award

consists of a plaque which will be presented to the Working Group Chair at the PES Summer

Meeting Awards Luncheon. A framed certificate will be presented to each Working Group

member at a designated meeting of the parent Technical Committee. Each Technical Council

Committee is urged to submit one electronic copy of nominations for each of these awards no

later than November 27.

Please forward suggestions for nomination for the next (2011) PES WG Recognition Award to

my attention, ASAP, so a nominee can be selected and forwarded to PES.

6.6 Transformers Committee Meritorious Service Awards

In 2008 we initiated a process of additional recognition for Meritorious Service and Outstanding

Contributions to the Committee. Suggested qualifications have been developed from a review of

similar awards presented by other IEEE Technical Committees or Societies. General examples

for qualification for the awards include the following:

To recognize continuing exemplary service in notable technical contributions to multiple

Committee projects/documents over a sustained period of time

To recognize an achievement of major value and significance to the Committee. The

achievement can be a specific, concisely characterized accomplishment, as opposed to a

collection of different efforts.

As with the IEEE Education Society Meritorious Service Award – “to recognize pioneering

contributions to the administrative efforts of the Society over a period of years, as evidenced

by dedication, effort, and contributions.”


FILE: f11-Awards 3 10-29-2011

If you have any additional thoughts on qualifications for Meritorious Service Awards, and if you

have potential nominees to suggest, please contact me. Award nominees will be reviewed by the

Awards Chair and the SC Officers.

6.7 Member Certificates

We will continue with the process of providing a framed Certificate, certifying Membership in

the Committee, to new Members. The intent is to provide a symbol of recognition of

Membership status, in a format suitable for display. The Certificate will indicate date of

acceptance into the Committee, and will be signed by the Committee Chair. We will also send a

framed certificate to everyone who is currently a member of the Transformers Committee. It was

originally intended to hand these out at the Thursday main committee meeting however in the

interest of time we have decided to mail these directly. You should receive your plaque by the

end of this year (2011).

This program is one small way of recognizing your support for the Committee. The Certificates

represent the appreciation of the Committee, and of your Committee Officers, for your service to

the Committee, to IEEE, and to our Industry. We hope you will display your Membership

Certificate proudly at your place of business, and encourage others to join us in our work.

6.8 Nominations for IEEE, PES, and Technical Council Awards

There are no nominations in these categories at this time. Regarding IEEE Fellow Nominations,

we have missed the opportunity for preparation of nominations for the 2011 Class of IEEE

Fellows. We need to think about nominations for 2012. Borrowing from the IEEE Awards web

pages (http://www.ieee.org/web/membership/grade_elevation/grade_elevation.html): “The grade

of Fellow recognizes unusual distinction in the profession and shall be conferred only by

invitation of the Board of Directors upon a person of outstanding and extraordinary

qualifications and experience in IEEE-designated fields, and who has made important individual

contributions to one or more of these fields.” Nominations, including references by at least five

present IEEE Fellows and optional additional endorsements, must be completed and submitted

by March 1 of each year for the following year’s Class of Fellows.

Respectfully submitted,

10.1 C57.13 Instrument Transformers – R. McTaggart – Unapproved Minutes

The Instrument Transformer Subcommittee met on Wed Nov 2 at 8:00

AM. 8 of the 16 members plus 15 guests attended.

Chair’s Remarks & Announcements

The schedule for future meetings was presented

The previous meeting’s minutes were approved as written

The status of all C57.13 standards was reviewed

10.1.1 Task Force Report: PARTIAL DISCHARGE IN BUSHINGS AND VTs/CTs

The task force on Partial Discharge in Bushings and PTs/CTs met on Monday October 31st, 2011, at 3:15pm with 50 attendees. Of those, 12 members and 38 guests with 3 guests requesting and granted membership. The meeting was opened with a request for patent disclosures and introductions. The minutes for the S11 San Die go meeting were pres ented. Volunteers were

reminded of the previously offered contributions to the draft; W. Hauschild offered t o have the section of shielding ready for next meeting after clarifying details with the Chair. The TF Chair presente d a draft version of th e preferred connection diagrams for

carrying out PD tests in laboratory settings for transformer bushings and instrument transformers both in balanced method and open-end method. Also, alternate connection set ups were presented and discussed. These diagrams are intended to be part of the guide. The diagrams will be e-mailed to the members of the task f orce for review and comments. The TF Chair presented a table su mmarizing the different aspects to be considered

prior and during the PD test includin g physical set up, oil ta nk size, use and size of corona rings, use and size of static shields in the oil side of a bushing, influence of ground planes during the test, cleaning and preparation of equipment prior to the test, set up and test connecti ons and instrumentation. This table will be e-mailed to the members of the task force for review and comments. The final item in the agenda was a presentation by Ba rrett Wimberly on Routi ne

partial discharge for CTs 72.5 kV and 800 kV. TF Chair Thang Hochanh request ed comments and feed back from the members

regarding the material and schematics presented. Meeting was adjourned at 4:30 pm.

10.1.2 Working Group on Current Transformers with mA range

(PE/TR/PE/TR/Instrument-WG C57.13.7) - Henry Alton Thirteen guests attended this working group on a “Standard for Current Transformers with 250mA range secondary current”.

Following introductions, the agenda was presented and accepted. The agenda was as follows. Patent issues were not discussed as they are now dealt with differently.

words on this and acceptance i. Technical Profile for Standard – Eddy So

d. Open Discussion/Questions & Answers e. Burden values

6. Next Steps

a. Final review round of document i. Burdens ii. Any other requirements that should be stated for this standard

1. Voltage limit? 600V limit for this standard iii. Send updated draft with additions of new categories.

Old Business (House Keeping) Action items and comments from the last meeting were reviewed. Any actions that remain open will be re-stated in the action section of this document. What follows are the actions closed and resolutions from the last meeting.

The topic of seeking coverage of a wider range of CT with 250mA secondary current and below.

o No new categories beyond the existing 80mA and 100mA categories were added

o One offer was tabled and rejected as it was a control device not a CT used with an electricity metering device. Action to review scope of C57.13.6 to see whether CTs used in

control circuits are relevant.

Express the limits of the parallelogram in a different form (Accuracy Limits Figure 1, 2)

o Motion and acceptance to leave these sections as they are. Standard burdens were also discussed and a point was made about specifying

impedance based on VA instead of these standard burdens. There is a need to investigate the test fixtures being developed by the National Research Council of Canada (NRC) to see whether there would be any impact in using this alternative (any considerations of standard burdens that may have been designed into the fixture). The burden rating numbers in the table should be clarified. (See actions)

Henry Alton to provide some information on the materials used. Closed Status Update: Showed this information to a working group

participant at the last meeting. Re-iterated Fe-based NANO-crystalline.

Henry Alton to provide the specification limits for signals immunity tests that would be present when an energy measurement is being made. Closed

Status Update (Nov01/11): Provide relevant EMC specs from MC LMB-EG-07 Section 6

o 3-5.2.2 and 3-5.2.3 below. Further details relating to these tests may be found in MIL-STD-461B.

EN55022 Class A, Class B-Immunity under operation o Equivalent to IEC 61000-4-6

IEC 61000-4-6, Electromagnetic compatibility (EMC) o Part 4: Testing and measurement techniques —

Section 6: Immunity to conducted disturbances, induced by radio-frequency fields

New Business A presentation of the calibration methodology was provided by Eddy So. The issue of voltage characteristics affecting measurement was again raised. It was noted in one of the simplified diagrams that there was no ground shown. There was one used. There was commentary that;

Current via capacitance was able to flow directly to ground and that there should be consideration of this capacitance.

Lower voltages classes where there is no shielding used may impact the accuracy.

Milliamp CTs should be capped at 600V

A CT offering for addition of a category of CT, having a secondary output current of 200mA was discussed. The application of this CT was expressed as given by the representative from Cooper Industries.

As you know, we manufacture Step Voltage Regulators, which are single phase regulating auto-transformers with self contained control systems. In accordance with our standard (C57.15 Section: 6.6.1-a), all regulators are equipped with an internally mounted CT. Further by reading section 9.2.1-d you would discover that the standard intends the internal CT to have a nominal secondary current of 200mA. This CT is provided for Line Drop Compensation, by which means, if the distribution line parameters are known between the point of regulation and the load, the voltage drop on the line from the regulator (point of regulation) to the load can be calculated based on knowing the load

current and this drop can consequently be compensated for. As profiled the application that this CT was expressed for was proposed to be other than for use in an electricity metering application and that this standard was specific to electricity metering applications. In discussion of this there was also some mention of Optical CTs.

Motions The standard should be clarified to reflect that the CTs types that are for use in

electricity metering applications only. This would be acceptable with the condition that there is no allowance for the same function in C57.13.6 which is where this standard is modelled from. Accepted

If no new categories of CT become evident in 30 days from today, this standard will proceed to the review stage with what it presently contains. Accepted

The first release of this standard will be capped at 600VAC. Accepted

Actions Vladimir Khalin to recover the CTs and forward them directly to Paul Millward.

Formalize data from initial testing and provide to Chairman. Detail how testing was performed Nov30/11

Forward the same samples to Paul Millward. The desire is to compare data based on the same samples. Nov30/11

Paul Millward to provide some test results on the same CTs that were being evaluated by Vladimir. Jan30/12

7. Henry Alton to provide some background clarifying the standard burden numbers will be given to support the previous action. Working Group to provide some more clarity on the burdens and make them more “Real World. There will be an update to this to reflect sources and approach.

8. Working Group to review the document and provide comments. A conference call will be arranged to review all comments. Feb15/12

10.1.3 Working Group for Revision of IEEE C57.13 Instrument Transformers – R. McTaggart

This working group met on Nov 1 with 14 of the 20 members present. The results of the survey on the applicability of C57.13.5 were reviewed and the conclusion that it should apply only when specified was clear. Next, the results of a complete review of the standard were discussed. A first draft will be prepared based on written and verbal comments, with the main changes being:

1 table for dielectric test voltages instead of 2 Incorporate the high accuracy requirements of C57.13.6 Proposed changes to section 8.1 to be included Bushing CT appendix

Changes to PD requirements (more discussion needed) The draft will be reviewed in the next WG meeting. Dr Eddy So made a presentation on the effects of voltage and load PF on CT accuracy, including test results on a 96 kV Combined VT/CT. The effect was present and more testing is planned.

10.1.4 New Business - Inclusion of Substation VT’s in C57.13 This was discussed and although many supported it, some were also opposed. It was proposed that the instrument transformer requirements should apply along with tests for % Impedance, regulation, etc. It needs to be addressed in the WG at the next meeting. 10.1.5 Adjournment

The minutes from the Spring 2011 San Diego, California meeting were approved as written.

Rick Ladroga announced that Michel Duval has been awarded the Herman Halpern award.

Review of recent activities:

Norm Field presented a re port for the DGA Data TF . There were 10 suppliers of data supplying 475,000 DGA sam ples representing 161,500 transformers. A full copy of the presentation will be posted on the web site.

Data for outright failed transformers, not in service (spares), non mineral oil samples, and samples not from transformers were removed from the data base. Samples from OEMs, repair shops, specified as “in-bottle”, without a t ransformer ID or sample date, duplicate samples, and blank or nonsense data entry samples were also removed.

There was data clean up required such as V to kV, text to numeric values, sample date format, and MVA basis.

For comparison of values in Table 1 of the Guide, the individual gas concentration data was analyzed.

Luiz Cheim presented on the analysis of t he database that both he and Lan Li n did. He showed a representation of the distribution of suppliers of the data, MVA, voltage class, oil preservation types, and the reason for the DGA test. Ordered statistics (percentiles) were used to analyze the data.

An analysis of H2, C2H2, and CO vs age was presented. The same was also shown for voltage class, MVA rating, and source of data. The CO values were well above the IEEE limit of 350ppm in all cases. He showed the same analysis for suspicious units.

Rates of gas formation (ppm/yr) for Hydrocarbons and for CO, CO2, and TDCG and using the Michel Duval triangular conditions were also presented. From the triangular evaluation, 10 conditions were identified with Michel Duval’s assistance. For completeness, the data was evaluated using Roger’s Ratios as well.

A question was asked if the WG expects to have limits based on the different ratings, age etc. Claude indicated that it is too early to determine that, but there could very well be more than one table based on age or voltage class.

Jim Thompson indicated that DGA has traditionally been used as a tool for trending. Does this data help with that aspect? The answer is that yes it would.

A suggestion was made from Joe Foldi that the data also be evaluated and compared to the IEC limits.

Rick reported that there has also been significant work on development of case studies.

Jim Dukarm gave a short presentation on DGA Survival Analysis.

Jin Sim asked about the use of artificial neural networks (ANN) to crunch the data for trending and analysis. This will have to be discussed and reviewed.

The meeting was adjourned at 4:30 pm.

10.5.2.2. C57.106 - Guide for the Acceptance and Maintenanced of Insulating (Minera l) Oil- Chair: Bob Rasor

Sue McNelly stated the PAR revision was issued because it will expire end of this year, Bob Rasor will Chair. Jim Thompson offered to be Vice Chair and has documents from the last cycle. This revision is not driven by any major technical issues but technical updating is needed. The last revision was driven due to moisture equilibrium curves per Tom Prevost. Reaffirmation is no longer an option due to IEEE SA policy change.

10.5.2.3. WorkingGroup C57.130 - Trial-Use Guide for Di ssolved Gas Analysis During Factory Temerature Rise Tests for the Evaluation of Oil-Immersed Transformers and Reactors - WG Chair Jim Thompson

The WG Report Given at the Sub-Committee Meeting, presented by Jim Thompson:

1. No quorum. 2. Discussed changing the scope from “Trial Use Guide” to “Guide”, and “oil” to “mineral oil”. 3. Discussion of issues regarding consensus of setting value limits. 4. Question: Are HVDC data included? Answer: Luis Cheim will supply such data.

The Minutes (unapproved) of WG Meeting as Submitted:

The working group meeting was called to order by Chair Jim Thompson on Tuesday, November 1. Unapproved Minutes Working Group Meeting for IEEE PC57.130 IEEE “Trial-Use Guide for the Use of Dissolved Gas Analysis Applied to Factory Temperature Rise Tests for the Evaluation of Oil-Immersed Transformers and Reactors”

The working group meeting was conducted on November 1, 2011 at Boston Massachusetts with 57 people in attendance, including 10 of the 30 working group members.

There was a request for patent declarations regarding the PC57.130 document and none given.

This document was in draft 18 when the decision was made to let the PAR expire in 2009. A new PAR was approved on June 17, 2010 and is labeled draft 19.

A motion and a second were made for approval of minutes. Also Tom Prevost offered a motion with a second to change the guide from a trial use guide to a guide and a motion with a second to add the word mineral to the title so the phrase reads mineral oil. After a show of hands indicated a lack of quorum, the motions were tabled. The motions (and the discussions below) will be reconsidered at the next meeting.

Data was presented and discussed for gas (ppm/hr) generation rates for a 1 per unit factory load tests. Jin Sim mentioned that the previous guide draft issues included--limiting the trial-use guide based on minimum gallons, gassing differences related to winding types e.g. disc versus layer designs, various loading rates d uring factory tests, and relatively small gas values as opposed to rep roducibility between labs.

Then discussion included precision statements from ASTM m embers Paul Griffin and Lance Lewand and other guests. ASTM 3612, Standard Method for Analysis of Gases Dissolved in Electrical Insulating Oil by Gas Chromatography, has precision statements that should be referenced in the document.

Other discussion included clarification that this is a g uide only and that statistical data gives information but due to b ias and uncertainty it d oes not provide absolute conclusions when establishing consensus values in the guide.

A suggestion was made to consider a tem plate in Excel for submission of the data, including a request for additional information. Another suggestion was made to document the ambient temperature data during the load test. Another suggestion was that the IEC documents 61181 and 60076-2 Feb. 2011 should be previewed and discussed at the next meeting. O ne commenter discussed that 90 percentile statistical values be used in the table rather than absolute values.

The Power Po int © p resentation and the current draft of the document will b e posted on the Insulating Fluids Subcommittee web site.

Task Forces

The following are proposed task forces for work on revision of the Guide. • Data Analysis

– Develop generic design category norms for Appendix A LTC Types – Variation of norms between users due to loading, maintenance, temperatures

A request for a volunteer to lead this task force was made. Jim Dukarm was asked and agreed to chair this TF. Shuzhen Xu, Tony McGrail, Mark To strud, Luiz Cheim, Prabhu Soundarrajan, and Stephanie Denzer volunteered to work on the TF.

• Other Diagnostic Methods to Add – Triangle (Duval) – Monograms (e.g. Jakob, Dukarm efforts)

A request for a volunteer to lead this task force was made. There were no voluntees to head up the TF, however, Fredi Jacob, Tony McGrail, Arturo Nunez volunteered to work on these topics.

Other Topics for possible future TF – Presence of Benzene and Toulene (Vijayakumaran Moorkath) – Use of word “fault” with DGA (Kent Brown) – This may be an issue to take up at the

IFSC meeting to make sure that we are aligned with terminology used in C57.104 and other documents.

Goals for next meeting (leads and TF members): • Data Analysis

– Gather data by type and operating conditions – Begin attempts to develop generic design category norms – Variation of norms between users due to loading, maintenance, temperatures

• Other Diagnostic Methods to Add – Review methods and if appropriate, develop draft text

• Other Topics – Benzene and Toulene? – Use of word “fault” with DGA – send to Insulation Fluids?

Discussions

Jim Dukarm gave an update on items that he has been working on or thinking about since the last meeting to try and help fill some of the gaps in the present guide.

Not much was indicated regarding actual diagnosis in the last revision due to lack of time. Since the document was completed, Jim has collaborated with some other people and has come up with some ideas for how to fill in some of the existing gaps in the existing document. For resistive type tap changers under stress, they may produce gases that may look like a fault has occurred. Jim indicated that if something is truly wrong with the tap changer, it should get worse. Therefore, looking at rates of change may be a way to identify a developing problem.

The other issue was t hat no generic limits are presently available. Jim indicated that when Michel Duval first published the triangle there was a normal zone. Thi s zone provides may provide some inherent limits. The triangle was developed based on a large data base. It may be possible to do model specific refinements using this method.

Cigre has iss ued a technical bulletin #443 for tap changers that has ta ken a sim ilar approach to categorizing LTCs.

Summary With five meetings between now and beginning next ballot we need to get started!

The meeting was adjourned at 11:45am.

10.5.2.5. Task Force PC57.147 - Guide for the Acceptance and Maintenance of Natural Ester Fluids in Tr ansformers - Chair: Patrick McShane, Vice-Chair: Clair Clai born, Secretary: Jim Graham

The Group Report Given at the Sub-Committee Meeting, presented by Patrick McShane

PAR Scope and Purpose wording developed and TF approved for submittal Task Forces after PAR Approval formed and Chairs assigned:

TF 1: Section 4 - Fluid tests & significance-Dave Hanson TF2: Section 6 - Handling & evaluation of NE as received- Lance Lewand TF3: Section 7 - Evaluation of NE as received in new equipment and after filling on site- Don Cherry TF4: Section 8 – Field Maintenance of NE- Stephanie Denzer and Jerry Murphy (Co-Chairs) TF5: Annex B – Additional Technical Info- David Sundin TF6: Field Application Guide and Equipment Evaluation - John Luksich TF7: Miscellaneous - All other Sections – Patrick McShane/Jim Graham (Co-Chairs)

Minutes (unapproved) of the WG meeting as submitted:

The meeting was called to order at 8:15 AM. An attendance roster was circulated. Member roll call was taken and a quorum was established. The minutes of the spring 2011 task force meeting were approved. The chair's opening remarks laid out the meeting agenda and summarized the task force status.

The first agenda item was a discussion concerning a proposal to consolidate existing fluid acceptance and maintenance guides C57.106, C57.111, C57.121, C57.141, and C57.147 into a single document. John Luksich gave the background which led to the proposal. Lance Lewand expressed a concern that a combined document would be much more difficult to get approved because of the broader scope and potential for a larger number of contentious issues to resolve during the balloting process. Consensus was the task force will continue with the revision of C57.147 after PAR approval and address the consolidation in the future.

The second agenda item was a review of the PAR Scope. Roger Wicks asked why the scope includes only natural esters. The chair responded that synthetic esters are rarely used in the North American electrical industry. A question was raised re the use of the phrase "vegetable seed oils" in the scope. This was resolved by adding "(e.g. vegetable seed oils ).

The third agenda item was a review of the PAR Purpose. The listing of equipment types was amended to read "distribution transformers, power transformers, and liquid-filled electrical equipment". The Purpose was also amended to address retrofilling of existing equipment more clearly. The chair advised a previous PAR submittal for a separate guide for field applications of natural esters was rejected with a recommendation to incorporate this material into a revised C57.147. Those present affirmed that material addressing field applications of natural esters should be added to the document. Lance Lewand asked if the reference to inhibitors in the purpose should be kept since there was limited information publicly available re what inhibitors were available for natural esters. Of the two manufacturers present, one shares with test labs

under non- disclosure agreement, the other does not share. The task force agreed to remove the reference. Juan Castellanos asked if C57.147 should address dissolved gas analysis. Sue McNelly responded that DGA was outside the scope of this task force and this topic would be discussed in the fluids subcommittee meeting later this week.

The revised Scope and Purpose were approved and will be included in the forthcoming PAR application.

The fourth agenda item was assignments of volunteers to chair the follow task forces as shown below. No work will start until after the PAR has been approved.

• TF 1: Section 4 - Fluid tests & … significance - Dave Hanson (chair)

• TF2: Section 6 - Handling & evaluation of NE as received - Lance Lewand (chair)

• TF3: Section 7 - Evaluation of NE as received in new equipment and filling on site - Don Cherry (chair)

• TF4: Section 8 – Field Maintenance of NE -Stephanie Denzer and Jerry Murphy (co-chairs)

• TF5: Annex B – Additional Technical Info - David Sundin (chair)

• TF6: Field Application Guide and Equipment Evaluation - John Luksich (chair)

• TF7: Miscellaneous - All other Sections - Patrick McShane & Jim Graham (co-chairs)

The last agenda item discussed was a discussion of items interest. Seventeen items were identified during the discussion. A list of these items will be posted on the task force web site. There was no unfinished business from the last meeting and no new business introduced.

SCOPE: This guide recommends tests and evaluation procedures, as well as criteria and methods of maintenance, for natural ester-based (e.g. vegetable seed oils) insulating fluids. Methods of reconditioning, field applications and diagnostics of natural ester-based insulating fluids are also described.

PURPOSE: There is growing interest in the use of natural ester fluids for dielectric coolant application in distribution and power transformers and other liquid-filled electrical equipment. Natural esters are also being applied in retrofilling of existing liquid-filled equipment. This guide assists the equipment operator in maintaining the fluid in serviceable condition. This guide, therefore, recommends standard tests and evaluation procedures of natural ester fluids. It also provides recommendations for field applications including field testing of equipment, methods of reconditioning and reclaiming natural ester fluids, and the analysis results at which reprocessing becomes necessary.

Task Force Action Items A PAR application will be prepared and submitted by the chair by the end of November 2011 incorporating the task force approved Scope and Purpose as shown below.

A conference call will be arranged as soon as possible after PAR approval with the volunteer task force chairs.

The meeting adjourned at 9:15 AM.

10.5.2.6. WorkingGroup PC57.155 Natural Ester and Synthetic Ester DGA Guide - Chair: Paul Boman, Secretary: John Luksich

Report given at the Sub-Committee Meeting by Paul Boman: o No quorum. o Dave Hanson presented lab test method and data results, which were similar to the Halstead

graphs. o Presentation will be posted at the TC web site. o Additional work is needed to determine if lab results are reflective of actual field experience. o Osward coefficient values has been requested, and some have offered to provide. How to list for

each ester product offered is being reviewed, as some of the expensive lab work was done under contract and the results proprietary.

o Question: Sue McNelly asked if the C57.104 data base includes any esters samples? Answer: Yes, and that data will be provided to the ester DGA wG. Claude stated the data is also available for other committee work.

Minutes (unapproved) of the WG meeting as submitted:

Meeting Date: November 1, 2011 Time: 9:30 AM

Attendance: 22 members out of 55 members were in attendance, total attendance was 66 and 5 people requested membership.

- Quorum not present - intend to approve minutes on-line or at next meeting with quorum - review Spring 2011 minutes; no comments or corrections

Roll call postponed for late arrivals

Continued business

2) Dave Hansen presentation Q: Were oil degradation products studied? A: Will be included in the continuing work

Q: Do the gases and acids make stoichiometric sense? A: Good question! Continued research is planned.

Q: Was the water content measured? A: No. Planning measure on next set of tests.

Q: How would inhibited oils compare with those tested? A: A subject for further study.

Q: Wouldn't the inhibitor affect the oxygen reactions? A: Oxygen was not present, so this degradation was not an oxidative process. Worth further study.

Comment: The large volume inception points look to be similar to those of mineral oil, so this could aid gas analysis down the line.

Q: Do these oils generate gases other than those used in mineral oil dissolved gas analysis that should be added to aid ester analysis? A: Don't think so.

Q: Will different esters require different analyses techniques?

A: Hard to say. We have data from lab studies but need real life transformer fault data.

Comments from two and agreement by all via applause: great job!

Further floor discussion Chairman How does this compare to Halsted's work? Was there a problem with lost gasses in liquid phase due to saturation? Dave Hanson: Halsted did vapor phase analysis, I think. Fredi Jakob: What about partial discharge? Chairman: Dave will have some results from his work with Univ. of Manchester. EPRI also has results. Lance Lewand: This study looks at oil only. We need to remember that the addition of transformer materials may change the gases. Fredi Jakob: What about uv penetration of syringes? Dave Hanson: Results will be available for the next meeting. Lance Lewand: The presence of O2 will also be important. Dave Hanson: We presented earlier the effect of light exposure on stored totes, so we have some data available for the guide.

4) We will use the silicone guide as a template. Mark Cyr: Ostwald coefficients should be included. Jim Mustacchio (NYCO): will investigate if available for synthetic esters. Lance Lewand: Labs put a lot of work into determining Ostwald coefficients, so may not want to share. Chairman: Want to thank the labs and manufacturers for all their hard work. CIGRE technical bulletin 443 gives partition coefficients for synthetic and natural esters.

Chairman: Need volunteers to convert the data spreadsheets into charts. Claude Beauchemin, Jerry Murphy, Roberto Asano Jr. and Joon Han volunteer. Chairman: Case studies of faulted transformers are needed.

5) roll call: 22 of 55 members present. No quorum.

End of meeting.

Other Items - Marc Cyr: Have Ostwald coefficients been adequately established? Restated desire which was first stated at Spring 2011 meeting. - John Luksich: EPRI presented their findings early on but have not yet issued a final report. Jocelyn Jalbert published a paper with his findings.

Jalbert, J., Gilbert, R., Tétreault, P., El Khakani, M.A., "Matrix effects affecting the indirect calibration of the static headspace-gas chromatographic method used for dissolved gas analysis in dielectric liquids", Analytical Chemistry, Vol. 75, No. 19, October 1, 2003, pp. 5230-5239

- Michel Duval: For method C, CIGRE recommends using gas-in-oil standards to calibrate the equipment rather than using published partition coefficients. - Marc Cyr: It would be helpful to include the coefficients calculated using the gas-in-oil standards along with the dissolved gas data so that WG members can review them. Labs should get the same coefficients if they operate using the same conditions (temperature, pressure). Including the coefficients with the data will allow the WG members to critique or correct the gas data we end up publishing in the guide.

Polled attendees about including Duval Triangle in guide- Response positive.

10.5.2.2. Task Force on P article Count Limits in Mineral Oil – Ch air: Mark Scarborough, Vice Chair: T.V. Oommen, Secretary: Paul Boman

The Report given at the Sub-Committee Meeting: • Oleg Roizman will provide a study from Eastern Europe on synergistic impact on dielectric

strength of three factors: moisture, particles, and dissolved gas. • Sue asked if the TF should continue. No response. She determined that the TF can continue

but without a time slot at the S12 meeting due to number of other active WG and TF of the SCIF.

TF meeting minutes (unapproved) as received:

Meeting Date: October 31, 2011 Time: 1:45 – 3:00 PM

Attendance: 16 members out of 36 m embers were i n attendance, total attendance was 47 an d 4 people requested membership. At the beginning of the meeting during roll call we onl y had 16 members present, so the meeting proceeded as without a quorum.

The meeting was called to order at 1:45 PM. Attendance rosters were circulated.

The following agenda was followed:

1. Introductions & Roster 2. Origins 3. Activities Since Spring 2011 San Diego Meeting 4. Member List / Quorum 5. Purpose / Scope 6. Presentation by Dave Hanson and Don Platts 7. Discussion 8. Adjournment

Since we did not have a quorum, we were not able to vote on the approval of the October 27, 2010 and April 11, 2011 minutes as written.

Teleconference activities were reviewed.

Scope and purpose were reviewed.

Dave Hanson and Don Platts provided a presentation on in-service equipment particle count data verses dielectric breakdown, moisture, acid number and interfacial tension. The presentation is posted on the web site. It should be noted that the focus of the TF is to investigate the need to establish particle count limits in new transformer oil and /or new transformers. The presentation was focused on in-service equipment.

Comments:

Mark Cyr: The D1816 dielectric tests have precision ranges that make it difficult to draw conclusion at a specific voltage.

Jim Dukarm: Using median values for the particle counts analysis in the presentation smoothes the curves but does not harm the integrity. Data should be used for population observation only.

Don Platts: Particle counts are useful for forensic analysis, cleanliness program (maybe) and effects dielectric strength (fluid properties). Don focused on the effects of particles on dielectric strength. Provided that the transformer oil is maintained and other tests are acceptable, particle count is not necessary.

Patrick McShane: There was a RTE study done circ 1977 on the synergistic impact on dielectric strength from contaminates including particles, water, and gas. Dave Hanson requested a copy of the study as he would like to reproduce the study if possible.

Mel Wright: In his experience, oxidized sample can hold more moisture and higher particles and still exhibit acceptable dielectric strength.

Dave Hanson: Thinks that the effects of particles is a multi-dimension model because data correlations presented.

Chair: Should Task Force continue? There was little response from the group. Interest in continuing is uncertain. The Chair will send out an e-mail survey to members list and ask if there is continued interest in this task force. The membership list will be modified as needed so a quorum can be established to approve previous meeting minutes and discuss next steps to close out this topic.

Don Platts: Stated that he was not certain what problem is trying to be solved.

Ray Bartnikas: Particle type is key. Fibrous particles are important if dipole moments are formed in electric fields.

Meeting adjourned at 2:45PM.

(Post Meeting Note: Chair attended the WG PC57.152 Field Test Guide meeting. The chair reviewed the current October 2011 draft of PC52.152 and there is a section on particle counts. This needs to be reviewed and revised so it meets the current ASTM and ISO standards. Chair plans on contacting WG PC57.152 chair.).

10.5.2.3. Task Force on Moisture in Oil - Chair: Bob Rasor

The TF Report given at the Sub-Committee Meeting presented by Bob Rasor: • Reviewed the current wording of the proposed scope. • Summarized the activities of the TF since initiation in 2009. • Two new presentations were held at the TF meeting. One focused on comparing when is

moisture saturation value is more useful vs. when PPM value is more useful. The other on the issue of oil quality and water interaction. Both presentations will be posted on web site

• Claude Beauchemin working on presentation

The TF Meeting Minutes (unapproved) as Received:

TF on Moisture in Oil Monday October 31st, 2011 3:15 pm Boston, Massachusetts U.S.

The meeting was called to order by Chair Bob Rasor at 3:20 pm. There were 66 attendees. 20 of the 42 members were present. Six requested membership.

Members attending were: Bob Rasor Claude Beauchemin Paul Boman Stephanie Denzer James Gardner Jin H. Sim Donald Platts Jim Thompson Mark Tostrud David Hanson

Terence Martin Oleg Roizman Shuzhen Xu Luiz Cheim Mark Scarborough Poorvi Patel Valery Davydov Barry Ward Juan Castellanos Donald Cherry

Attendees requesting membership were: Lisa Colby Mike Lau Shawn Luo Pugazhenthi Seluaray Mahendea Soni James Mustacchio

Agenda 1. Roster was distributed 2. Roll call was taken 3. Reviewed scope 4. List of recent conference calls and meetings were given 5. Presentation was given by Bob Rasor that included:

i. Brief description of task force ii. Review of past data

iii. Recent case studies 6. New data presented

1. Data examples from online monitors in respect to relative saturation from Dr. Roizman.

2. Recent case studies from Bob Rasor.

3. Dr. Davydov presented a case study correlating moisture, acid, IFT and dielectric break down and how they interacted with the given scenarios.

In summary, the TF presented data to demonstrate the many trends t hat can be seen with moisture and how all data parameters may need to be considered.

Data was p resented from online monitors and Karl Fischer testing. There was emphasis on different moisture scenarios that would require different measurement parameters (relative saturation or ppm).

Data examples also demonstrated that moisture content (ppm) responds to temperature and that that season affects m oisture data. Relativ e saturation was shown to stay relatively stable as compared to moisture content on these graphs. When oil temperature increased, water content also increased dramatically, and proof was displayed to show th at this shifting between acceptable and unacceptable levels can occur within days.

7. Discussion and questions followed 8. Dr. Davydov presented his case study 9. Meeting was adjourned at 4:30pm

Comments provided at the end of the meeting regarding the presentation include the following: • A concern was raised that the data presented doesn’t directly measure moisture in

the paper. • A statement was made that the current standard is not useful when temperature is

not taken into consideration. • It was requested to have the presentation posted to the IEEE website. • It was suggested to take oil age and condition into consideration when analyzing

moisture in transformers.

Ad Hoc Activity Reports

o IF Standards Consolidation Review, Chair: Tom Lundquist

The officers of the Transformer TC and the Standards SC have recognized a need for consolidation of the C57 standard series where it makes sense. An example would be having one general insulating fluids standard acceptance and guide, and have the value lim its be listed for each specific type of fluid.

Sue presented a statement from Tom Lundquist, chair of the TF: “The task force is unanimous that combing these documents will be an advantage to the industry. There are a significant number of pages that are repeated in all documents that will be reduced to only one time. Also puts all fluids into one location. The combining will not be a short project but shouldn’t be too bad since we are dealing with already approved guides. We took a quick look at including IEC but decided it would not work well as IEEE covers this well.

Jim Thompson stated that combination of the oil guides would be difficult due to the large amount of information required to cover the various fluids.

Tom Prevost disagreed that the document would cause improper mixing of types of fluids, and indicated that there is too much repetition in standards now. Tom indicated that his opinion was that it may be more important to have t he information in one document. Claude Beauchemin agreed with Tom Prevost and indicated that it w ould be cheaper to buy a combined guide than separate guides.

Jim Thompson stated that the silicone guide already warns against mixing with mineral oil and that combining into one guide will be confusing.

Susan McNelly indicated that combining the documents is not indicating oils should be mixed, there could be common boiler-plate language and then separate sections as needed for identifying differences.

Tom Prevost made a motion to accept the findings of the TF and to pro ceed with combining the oil guides.

Bill Bartley supported the motion indicating that it is a struggle to handle all 104 standards of the Transformer Committee, of which there are presently 55 active PARs.

Clair Claiborne stated that Lance Lewand has indicated that it will b e very difficult to work on revisions if combined.

Jerry Reeves volunteered to work on a TF that would develop a comparison of the different oil guides. Jim Dukram agreed with Lance, indicating that it would introduce an element of rigidity. Jim Thompson indicated a concern that it would re sult in guide four times as thic k as each individual guide and that it would be very confusing to fill new equipment based on one guide.

Don Platts called for a close to discussions and to vote on the motion on the floor to combine all four Guides (C57-106, -111, -121, & -147). A vote was taken and passed with a narrow majority of 12 of the 23 WG members present. D ave Hanson offered to help write a sect ion regarding mixtures of the fluids and possible consequences.

For the immediate future, the WGs for C57.106 and C57.147 will continue to work separately on revisions of their resp ective documents. In p arallel with these efforts, a g roup will be formed to look at the best way to combine the documents. This effort may end up waiting until the work with the individual guides is completed. Discussions with IEEE will need to be had to determine what can or can’t be done in parallel on this effort. After the meeting, Tom Prevost offered to chair a TF to work on the combination effort.

o New TF of the Standards Subcommittee has been formed to study and report on Nomenclature Consistency for Insulating Fluids, Chair: Patrick McShane:

10.3.2.4 1276 Guide for the Application of High Temperature Insulation Materials in Liquid-Immersed Power Transformers

A PAR has been submitted for 1276. 10.3.3 Working Group and Task Force Reports 10.3.3.1 Working Group for the Revision to C57.91 Loading Guide –Don Duckett The working group was called to order by Chair Don Duckett at 9:35am. Vice Chair Carlo Arpino and Secretary Susan McNelly were also present.

There were 25 of 55 mem bers present (a quor um was not achieved) and 51 guests. New requests for membership will not be entertained due to the Guide having gone to ballot.

Agenda: 1. Member Roll Call/Introductions 2. Previous meeting minutes approval 3. Status of the present Guide 4. Adjournment

Introductions of members and guests were made.

Minutes from the Spring 2011 meeting in San Diego, California were not approved.

Status of the present Loading Guide: C57.91 D10 of the Guide has been submitted to REVCOM and is o n the agend a for the December 2011 meeting.

NEXT STEPS:

What is the future work for this WG?

1. Review of comments and past work not addressed due to time limitations.

Jin Sim brought up the issue of condition based loading. If the transformer is in good condition it will h ave different loading factors than a tran sformer that is not in goo d condition.

2. References to recent papers and new and updated work.

3. “Liquid-filled” vs “Mineral Oil-Filled” – New insulation systems

Sue McNelly commented that at the ADCO M meeting this had been discussed and the thought at that tim e was that trying to incorporated other fluids into the Guide would make it too long and unwieldy. This will need further discussion.

2

4. Annex G vs Clause 7 issues.

Jin Sim wants to make sure that we do not redo what we have already done.

5. Setting user ratings to support NERC/FERC guidelines – Expand/rework Annex C?

C57.119 has recommended practices to determine m and n constants.

6. Recommended data and formats for data needed on future manufacture test reports.

Don Duckett indicated that obtaining this data is often difficult to get f rom the user. Most of the time only nameplate information is available.

7. Seasonal environment/Ambient and load data collection

Don indicated that this information is ve ry spotty as we ll. Jin Sim indicated that much of this information should be available.

8. Work between now and Nashville?

Bruce Forsyth Chair of the Insulation Life SC indicated that the scope of the W G has been met. The WG as signment has been met and it should now go to the SC for determination on whether there is need to reopen for future revision or to go in other directions. There m ay be other priorities that require further work. Therefore, this will be the last meeting of this WG.

Additional comments:

There was considerable discussion on the topic of GIC events.

RamsisGirgis brought up the issue of GIC. He indicated that you will have a cycling event of low levels for 20 or so m inutes and a higher peak for 2 or 3 m inutes. There can be overheating of the winding during these conditions. He asked what temperature limits should be allowed during these types of events. Would it be equivalent to emergency loading levels or something higher?

Don Platts asked that the loading guide has been developed as a tool to try and determ ine the temperatures. He indicated that there are no to ols available to calculate the tem perature for what Ramsis was asking.

Ramsis indicated that a capab ility curve h as been developed to indi cate how m uch load should be allowed during GIC events. There is typically close to an hour of notice of GI C events before they occur. The windings have a certain temperature at a certain load, therefore if the winding is at 100C under a certain load and you add the GIC current on top of that, what temperature should be allowed for this event.

Under the GIC event, the m anufacture can ca lculate what the tem peratures will be , but the question is what is acceptable. The GIC cycle is every 11 to 12 years and who will

3

experience it depends on the strength of the GIC event. Ramsis indicated that this is an urgent critical issue. What should be allowed for that peak temperature, is it 160C or 180C?

HasseNordman indicated that he w ould consider this to be covered by the loading guide as a short term emergency loading situation.

Jin Sim indicated that there are other sources of DC than just GIC events. He indic ated that NEMA RI9 has traction duty type information. He indicated that he would not recomm end 180C. He indicated his limit would be 140C. He indicated that this group cannot indicate an allowed temperature, it can m ake a recomm endation and indicate what risks m ight be associated with loading to a recommended level.

Comment was made that GIC is not a Loading Guide issu e as the GIC affects the core not the winding.

Ramsis is on the NERC comm ittee and is loo king for a yes or no answer for a report that needs to be submitted to NERC. A request was made of membership present as to whether use of 180C winding temperature would be acceptable (sam e as the short-term rating in the present guide) for the short 2 to 3 m inute GIC peak currents. A straw poll was taken and the consensus (approx 35 to 1) was that this woul d be acceptable to use as a suggested loadin g curve.

Transformers (C57.100) – Roger Wicks C57.100 was successfully re-circulated and submitted to the Standards Board for approval. The process, time line and significant changes were reviewed. In addition, Roger Wicks thanked the Ballot Resolution Group consisting of Don Platts, Tom Prevost, John Luksich, Terry Drees and Jin Sim for their efforts. 10.3.3.3 Task Force on High Temperature Liquid-Immersed Transformers

(PC54.154) – Richard Marek The seventh meeting took place on Monday, October 31, 2011 in the Pacific FGH Meeting Room at 1:45 pm, at the Renaissance Waterfront Hotel, Boston, Mass. Introductions were made and attendance sheets were circulated. The Chair noted that two members were changed to guest status due to inactivity. They were notified by email and there was no response. A third member indicated that he would not be able to attend on a regular basis and

his status was changed to corresponding member. At 33 members, a quorum was established with 21 members and 44 guests present. The minutes from the San Diego meeting were approved as submitted. Gary Hoffman was thanked for his extensive work reformatting the document from a guide to a standard. The members of two task forces were also thanked for completing their work since the last meeting. The first task force dealt with re-designing Figure 4. The second developed an informative annex summarizing the evidence supporting the thermal enhancement of kraft paper by ester liquid. Both were added to Draft 7, which was released for a joint survey of the Working Group and the Insulation Life Subcommittee in August. The survey was disappointing however, with only 43 percent of the 98 responding and only 59 percent of the Working Group. This was after three reminder emails. 86 percent of the responses were affirmative and 18 submitted comments. Of the 90 or so comments, about half were editorial. Copies of the comments were sent to all members and guests before the meeting. Most of the rest of the meeting was spent resolving these comments. The chair presented 63 major comments, grouped in order by page number with a suggested response for most. 24 of these comments were discussed in the meeting and most were accepted. A notable exception was a comment by Joe Foldi questioning the 110 and 130-degree temperature rise limits in Table 2. Bubbling in mineral oil was the concern and Jin Sim agreed. The Chair pointed out that these are the same limits taken from the 1997 version of IEEE Std 1276 and bubbling was addressed then. The Chair will provide specific references from this document, but the matter was left unresolved. One recurrent comment concerned the meaning of the term temperature class. The Chair presented some background on how temperature classes are addressed in IEEE and IEC standards, including the dry-type standards, where multiple insulation system, temperature classes have always been the norm. In contrast, the concept is foreign to liquid-filled transformer standards, which do not reference temperature classes, since only two classes are commonly used. This lead to a proposal to reference the insulation system test procedures in C57.100 and to define how the results relate to a temperature class. The proposed table will show the relationship to the hottest spot temperature for each temperature class. The proposal also included the addition of an intermediate class of 140 as a way to resolve Working Group issues with tabulated temperature limits. With a large number of unaddressed comments, Jin Sim suggested an intermediate teleconference discussion, since the goal was to ballot the document before the 2012 Spring meeting. A show of hands indicated support and the Chair agreed to issue Draft 8 with resolved changes and suggested all submit comments before the discussion. The meeting adjourned at 3:05 pm. 10.3.3.4 Working Group for Temperature Rise Test Procedures Section 11 of

C57.12.90 - Paulette Powell

The WG on Temperature Rise Test Procedures in Section 11 of C57.12.90 met in the Pacific D room of the Renaissance Boston Waterfront Hotel in Boston, MA at 11:00 AM. Introductions of members and guests were made. The chair reviewed requirement for quorum and took count of the membership. There were 18 members and 60 guests. A quorum was established. The minutes of the April 12, 2011 meeting in San Diego were approved as written. Projects: After introductions, we proceed to discuss th e first proposal concern ing the clause 11.1, the loading back m ethod for tem perature rise test . The proposal was to m ake this m ethod mandatory for transform ers 1500 kVA 3-phase, 500 kVA 1-phase or lower. After som e discussion the proposal was first changed from mandatory to preferred by Mr. Marcel Fortin, and finally an agreem ent was achieved, by the proposal by Mr. Mark Perkins, leaving the same wording as it is now in the standard, but changing the order of appearance of the methods. The loading back method will appear fi rst as item 1), followed by the sho rt circuit method as item 2). The second clause to be reviewed was the 11.1.2.2 of the loading back m ethod,that requires both transformers, supply and under test, to be identical. T he proposal was to allow these transformers to be differ ent, allowing the supply transform er to be equal or higher kVA, and up to 10% voltage different than the transf ormer under t est. There was m uch discussion because the wording of the proposal was conf using. Finally it was proposed, by Mr. Bertran d Poulin, to perform a major change to the clau se stating th at what is really important is to provide proper voltage and curr ent to the transformer under test, and the rated characteristics of the supply transformer are irrelevant, and have to be defined by the test area. A new proposal will be prepared, by Mr. B ertrand Poulin, and sent to the working group m embers for approval. Old Business The survey to the IL and DT subcommittees regarding sub-clauses 11.2.2 c, d and f will be presented at the next meeting. New Business There was no new business. The Meeting was adjourned at 11:48 AM. Respectfully submitted, Juan Castellanos, Co-Chair MarnieRoussell, Secretary

10.3.3.5 Task Force on Furan Testing – ShuzhenXu The meeting started at 9:30am and adjourned at around 10:45 am on Oct. 31st, 2011. There were 73 attendees with 16 furan task force m embers. The task force h as 60 members so the meeting couldn’t have a quorum. The following activities were taken place during the task force meeting Introduction of members & guests Task force activities and status update & report

During the discussion of the position, the following suggestions were received from the audience: (a) Adding loading factor: <20%, 20%~75%, >75%, into the data collection list (b) Add oil temperature into the data collection list (c) Regarding transformer type, add “wind use” into the list (d) Add “particle in oil” into the data collection list (e) List “must have” items on the proposed data collection list.

Open discussion on the following items: (a) Is there any need to collect furan data from field transformers for analysis?

If yes, how? (b) Should the task force propose a working group to the subcommittee for

developing a guide document on furan analysis? Since the m eeting didn’t have a quorum , we couldn’t vote on whether the task force recommends the f uran data collection. But the a ttendees were asked during the meeting to vote their opinion on whether data collection is necessary (29 attendees votes yes and one voted no). Also the consensus of attendees is having a working group to develop a guide on furan analysis. 10.3.3.6 Task Force on Temperature Rise of Non-current Carrying Metallic Parts

– Jeff Ray This Task Force has completed its work. Its recommendation was presented to the Subcommittee. See New Business. 10.3.3.7 Task Force on Moisture Estimation in Transformer Insulation – Jin Sim The Task Force on Moisture Estimation in Transformer Insulation did not meet during the Spring2011 Transformer’s Committee meeting. The TF anticipates having a draft of the paper by the end of the year. Once complete, the draft will be circulated in the TF for comment. 10.3.3.8 Task Force on Winding Temperature Indicators - Phil McClure

The results of this Task Force should be available soon. 10.3.4 Old Business: No old business. 10.3.5 New Business: The Task Force on Temperature Rise of Non-current Carrying Metallic Parts presented its recommendation. A motion was made to accept the recommendation of the Task Force. This motion was approved. There was considerable discussion about Table 8. The following points were made.

Are there any temperature limits for material in contact with air? The paper used as wrap on conductors is thermally upgraded. However, the

pressboard used for spacers is not thermally upgraded. It was pointed out that this table applies to non-current carrying metallic parts so it would not apply to spacers.

It is not effective to impose limits in a guide. This should be done in a standard.

The table has been labeled correctly. The intent is to help users evaluate the risk of temperature in the transformer.

Design calculations are provided in the loading guide. An objection was made to the wording as it does not include glass fiber.

10.3.6 The meeting adjourned at 9:15 AM. Bruce Forsyth Chair, Insulation Life Subcommittee

Don Duckett made a presentation on “Financial Math” discussing the basics of engineering economic calculations and the basic equations for utility loss evaluation A and B factors. Don also presented a spreadsheet tool to make these basic calculations. These will be made available on the website. Don also demonstrated a computer program that considers uncertainty in the inputs and the resulting range of variation in the A and B factors. A discussion of uncertainty followed with the direction that the guide will address all forms of quantifying uncertainty, including Band of Equivalence or BOE. The first draft D11 was reviewed and will be on the website following this meeting. A more detailed review will take place at the next meeting in Nashville.

10.4.2 PCS WG on “Test Code C57.12.90” – Mark Perkins, Chairman; Craig Stiegemeier, Secretary 1. Introduction of members and guests 2. Membership review

Craig Stiegemeier reviewed recent changes to the Working Group roster. After these changes, the Working Group now has 71 Members, 1 Corresponding Member and 257 Guests. Any Member missing the last two Working Group meetings has been moved from Member to Guest status. A review of the current roster of members was presented to the attendees. After the review, a roll call found that 39 members were present at the meeting, constituting a quorum of 55% of the Working Group membership.

3. Approval of minutes from the Spring San Diego meeting The Chair noted that the minutes from the San Diego meeting were distributed to the Working Group before the meeting by E-mail as well as on the Committee website. After a call for comments or corrections and receiving none, David Wallach made a motion to approve the San Diego minutes, Robert Thompson seconded the motion, and the minutes were approved by the membership as written.

4. Old Business Revision of Section 6 and 7. Final survey resulted in 59 members approving, one abstaining and with 3 members approving with comments. The chair presented a review of the 3 comments received on Sections 6 and 7. Following are those comments: Robert Thompson commented that the Wye-Zigzag illustration should show H1

connected to X1. The Chair noted that this comment will be incorporated into a revision of the comments

Jennifer Yu offered the following comment: “The portion directly above Figure 9 could be explained in more detailed text, for example, apply voltage between H1-H2 terminals, and measure voltage between X1-X2 terminals. This would make it much clearer to read and understand, instead of some symbols.” A discussion of this comment was held. Bertrand Poulin noted a recent test floor experience. Baitun Yang of PA Transformer questioned the practice of creating a virtual neutral. Kipp Yule noted that there could be some confusion when using the Phase A, B and C designation, which is similar to the following comment from Barry Ward. The Working Group agreed that the comments surrounding the figure were adequate to explain the concept.

Barry Ward offered the following comment: “Paragraph 7.1.4: I think the diagram should show which phases are A, B and C. I’ve used the following diagram in a recent document which you are welcome to have if you want.” The Chair suggested



that this would not impact the survey and may make the figure clearer to understand. Thompson made motion, Joe Melanson seconded the motion, and 39 members approved, no one disagreed with making the change to this figure.

Any other Old Business? There was no other old business

5. New Business

Revision of Section 8 – No Load Loss Measurements Voltage waveform issues with no load loss measurement Use of Capacitors for wave shape improvement

The Chair suggested that the standard is up to date for most cases as long as it is followed correctly.

Connections are properly made Voltage is properly set Average voltage reading voltmeter is used

The Chair suggested that the effect of waveform distortion could be addressed better with a revision of the standard. He suggested that a better approach may be to update the guide. Ramsis Girgis commented that Section 8 has a number of different figures showing how to make the no-load loss measurement connections. Waveform may be a different situation. The primary concern is determination if the waveform deviates significantly from a sine wave. Bertrand Poulin suggested that there is missing guidance, but he suggests that the clarification should go into the guide, and not the standard. The waveform could be improved by: Inducing to a different winding Using a stiffer (higher MVA) source Applying a capacitor to the source terminals (not to be used on a generator due to self-

excitation concerns)



These all basically lower the source impedance at the higher harmonic frequencies. The last method is likely the one which most users are least familiar. The chair then presented some information from technical literature demonstrating the benefits of capacitors for correcting a badly distorted voltage waveform when a transformer was tested at 115% excitation voltage. Arnold Carlos commented on the need for 115% over-excitation. Marcel Fortin made comments around the need for accurate measurements to address harmonic issues in wind applications. Bertrand Poulin emphasized that a simple 5% correction factor limit is not adequate to assure the wave is as clean as possible. Ramsis Girgis emphasized that a correct measurement of exciting current was what is needed. It was asked if anyone requires measurement of no-load loss and excitation current at voltages greater than 110%. Mike Spurlock of AEP noted that they required the measurements up to 120% over excitation which is used by their system analysts. He agreed that their desire is to have a waveform be as close as possible to a sine wave. He favors something that would go into the standard or guide to suggest an approach so manufacturers get as close as possible to ideal. Steve Antosz suggested that this falls under C57.123 loss measurement guide, and it really doesn’t fall into the work undertaken by this working group. Bertrand Poulin believes that some of this should go into the test code and some into the guide. If the guide is changed first, then the test code will have something to refer to. These minutes request that the guide be updated. It was published in 2009, and is not due to be updated for some time. The Chair committed to reviewing the 5% correction paragraph to make it clearer at the next meeting. Bipin Patel has offered to conduct an independent review section 8 and come back with comments. The Chair asked for volunteer(s) to come forward with their comments in reviewing Section 8. Shamaun Hakim wants to see that measurements occur with the LTC in the bridging position to correctly measure the average losses and to help confirm proper operation/connection of the LTC. Joseph Melanson suggested that core loss should be measured in 15 raise for any transformer that has an LTC. Jim Harlowe noted that this concern was addressed in the voltage regulator standard (C57.15) and resolved through a no load loss measurement taken at 4 positions that would include bridging positions for reactive tap changers. The chair suggested that the issue of tap changer positions for no-load loss measurement of transformers with reactance type tap changers should be brought to the attention of the Working group on PCS revisions to C57.12.00 for discussion and inclusion in the standard. Ramsis Girgis suggested that we bring the Overexcitation Task Force recommendations up at the next meeting for review by this group. Craig Stiegemeier committed to get those suggestions to the Chair. After the meeting, Dinesh Sankarakurup approached the Chair, suggesting that we look at how well the voltage is balances as one of the checks when performing the no-load loss test. This will be reviewed at a future Working Group meeting.



10.4.3 PCS TF on Dielectric Frequency Response – George Frimpong, Chairman; Poorvi Patel, Secretary 1. Meeting Attendance The TF on DFR met on Monday, October 31st, 2011, at 1:45 PM. A role call showed 13 members and 53 guests in attendance. Three guests requested membership. 2. Approval of previous meeting minutes There was a quorum of members present and the minutes of meeting from the Spring 2011 meeting in San Diego California were approved with changes. 3. Presentations of task reports Four groups were formed during the San Diego to handle various aspects of the project. These groups presented progress reports at this meeting. � Subtask 1 – Literature Survey George Frimpong presented a list of abstracts from papers related to the modeling and estimation of moisture in transformers using DFR and other dielectric response methods. In all a total of 25 key papers have been identified, some of which deal with verification of DFR for moisture estimation. o Mary Foster from Omicron suggested the inclusion of the CIGRE Working Group D1.01 (TF 14), Report 414 on Dielectric Response Diagnoses for Transformer Windings, 2010. � Subtask 2 – DFR Method Description Peter Werelius presented the material that has been put together to explain the basics of the DFR method. � Subtask 3 – Verification/Validation Tom Prevost and Diego Robalino presented case studies on transformers for which DFR measurements and other moisture determining measurements (dew point and Karl Fischer on paper samples) were performed. Tom requested anyone who has cases of DFR moisture measurements in conjunction with other moisture measurements to send these to him and Diego for review and inclusion in the task force report. For completeness we ask also for cases where DFR did not work in estimating moisture in the solid insulation. Tom presented a list of information to include with the cases. o The chair clarified that the task force will focus only on cases related to moisture determination in power transformer solid insulation. o A table to address DFR measurement parameters and to quantify their diagnostic value was presented. The table will be reviewed by the subgroup before the next meeting. � Next Step for Subtask 3 o Complete draft of this section by end of January 2012 and distribute among subtask members for comment � Subtask 4 - Mario Locarno presented a review of existing IEEE, CIGRE and IEC documents that have a relation to moisture estimation in transformer solid insulation. In all about 20 documents were found that mention moisture estimation or DFR. 4. Comments and Questions: � A comment was made by one of the guests that the effect of several parameters that may affect moisture estimation using DFR must be addressed in detail by the task force, these being: o Effects of aging (e.g. low molecular weight acids) o Effects of temperatures o Effects of design parameters o Validation on older transformers



o Reliability of the databases used for analysis � The chair responded that the scope of the task force was to find if there is enough validation that DFR can be used to determine moisture content of solid insulation in transformers. If the recommendation is to develop a guide, all the limitations would have to be addressed by the ensuing working group. � Project Time Table: � Before Spring 2012 Meeting – i. Complete draft report and circulate among TF members for comment ii. Complete final draft report � Spring 2012 Meeting – Review final draft and obtain comments � After Spring 2012 Meeting – Address comments and submit final report to PCS Chair � Chair asked for comments on content and outline of preliminary draft TF report that was sent to the group. No comments were made.

10.4.4 PCS WG on “General Requirements C57.12.00” – Steve Snyder, Chairman; Enrique Betancourt, Secretary The Working Group met at 3:15 PM on Monday, October 31, 2011, with 31 members and 62 guests present. As the current Working Group membership stands at 61 members, we did have a quorum at the meeting. The following (18) guests requested membership, which will become effective only after confirmation of attendance at two (2) consecutive meetings : James Graham Pike Energy Solutions Jose Izquierdo Siemens Servicios S.A de C.V David Murray Tennessee Valley Authority Sanjib Som Siemens Energy Sergiy Razuvayev Delta Star Inc. Kirk Robbins Exelon Nuclear Tauhid Ansari ABB Inc. Amitav Mukerji ABB Inc. Oscar Pinon Garcia WEG Joshua Verdell ERMCO Terence Martin GridSense Jagdish Burde Virginia Transformer Bill Chiu Southern California Edison Michael Craven Patterson & Dewar Engineers David Harris Waukesha Electric Systems Jill Holmes Bureau of Reclamation Tom Melle Waukesha Electric Systems John Herron High Volt - Reinhausen Following introductions, the minutes of the April 11 San Diego Meeting were approved.The meeting agenda was presented.The meeting began with reports from the two Task Force chairmen on the old business items as follows : WG Item 82, C57.12.00 - 2000 Section 7.1.4.4 Stabilizing Windings The Task Force on Stabilizing Windings met earlier the same day. This group has been working now for three years to resolve the subject of default kVA rating for stabilizing



windings. A new clause was prepared by the group for inclusion in C57.12.00, and the text was surveyed among the Performance Characteristics and Insulation Life Subcommittees prior to this meeting. With the results of this survey producing only affirmative responses and few minor comments, we deem the work of this task force to be completed and the new clause will be submitted for the next ballot of C57.12.00. Owing to the strong interest expressed by the participants, the Task Force has requested to be upgraded to a Working Group specifically to develop an application guide for tertiary and stabilizing windings. The Title, Scope and Purpose for this new document were discussed and have been submitted for review and approval of the Committee Officers. WG Item 87, C57.12.00 -2002 Table 18 Short-circuit apparent power of the system to be used unless otherwise specified. A Task Force was formed at the Fall 2010 meeting to review short circuit currents listed in Table 18, in response to a comment from the 2006 ballot. The chairman, Bruce Forsyth, presented a new set of proposed figures for the table. There was intensive discussion on the validity of the new numbers, as some are higher and others lower than the original ones. One point of controversy was the criterion of limiting maximum short circuit currents to maximum ratings of existing circuit breakers. Following a lot of discussion, the chairman proposed sending the new proposed Table 18 for survey within the membership of the Performance Characteristics Subcommittee and this Working Group, to collect a more general view. Under new business, the WG began discussions on these issues : WG Item 96, C57.12.00 -2010 Table 18 Routine, design, and other tests Requested Change (J.Foldi) : “Resistance measurements should be done on all taps for Power Transformers.” Currently, Table 18 only calls for resistance measurements on nominal and extreme taps. First it was discussed among the participants if, for reversing LTC´s, it is necessary to cover the full range of taps. Secondly, the necessity of including QA tests within the standard was questioned. After much discussion, it was agreed that we will conduct a survey within the Working Group with a clearly defined document describing the requested test and the ramifications of the proposed change. Joe Foldi will assist the chairman in preparing the document. WG Item 97, C57.12.00 -2010 Table 18 Routine, design, and other tests Requested Change (J.Foldi): “Could the details of the operational tests on the LTC equipment under full voltage (during No-Load test) and under full current (during Load loss test) be described here ? The details of the LTC operational test should be described in C57.12.90, but the requirement for the test itself needs to be added here.” Before the discussion within the group, Joe explained in detail his request: for LTCs, inclusion of electrical as well as mechanical tests, as it is specified in IEC standards. Once again we concluded that an explanatory document needs to be prepared and surveyed among the Working Group before engaging in detailed discussion. Joe Foldi will assist the chairman in preparing this document. WG Item 98, C57.12.00 -2010 Title and Scope Requested Change (Kimberly Mosley) : The title of Standard C57.12.00 suggests a scope covering regulating transformers. The body of the document limits its discussion of regulating transformers to load tap changing with a vague mention of other types. Ferroresonant regulating transformers are not discussed and the document either should



cite these as specialty transformers not included in the scope or reference an applicable standard, or include some discussion. The chairman reported that the Standards WG commented during ballot resolution that there are many “specialty” transformers, and it would be inaccurate to single out just one (such as ferroresonant transformers) as an exclusion. After a brief discussion, the Working Group agreed with this response by a vote of 29 to 2, and the subject is considered closed.

10.4.5 WG on “IEEE Standard Requirements, Terminology, and Test Procedures for Neutral Grounding Devices”, PC57.32 – Sheldon Kennedy, Chairman; Fred Elliott, Vice-Chair

The Neutral Grounding Devices working group was called to order at 3:20 PM on November 1, 2011. There were 19 attendees: 11 members and 8 guests, Copies of the previous meeting minutes were distributed.

1. Introductions were made. 2. The agenda for the meeting was reviewed and it was determined that a quorum was

present. The minutes from the San Diego meeting on April 12, 2011, were approved without comment.

3. The status of the project was reviewed. A straw ballot of the Performance Characteristics Subcommittee had been made, and determined that sufficient consensus for the document to move to sponsor ballot had not been accomplished. The content of the technical comments received will require additional work to revise the document. Unfortunately, there is insufficient time to complete this before the expiration of the PAR at the end of the year. Since the PAR had been extended three times, it is not possible to request an additional extension. Therefore, the PAR will expire, and a request for a new PAR has been submitted for the December NesCom meeting.

4. Further, it was determined that new officers would be needed to continue the project under the new PAR. Sheldon Kennedy volunteered to be the Chair, and Fred Elliot to be the Vice Chair/Secretary.

5. Since there was a quorum present, it was decided to continue the work on the standard. The working group proceeded to review comments received during the straw ballot. The major concern raised during the ballot was the inconsistency in requirements

between the common clauses and the specific grounding device clauses; and that the information for any particular device was spread throughout the document. After discussion of these issues, a motion was made to include all of the information needed to describe the characteristics and testing of a particular neutral device in its own section. After discussion the motion was approved.

Discussion then continued on the testing requirements for each neutral grounding device and as to whether this should be in a common section or with each device. After continued debate the working group decided that it was too early to determine if the testing could be combined, and decided to wait until the individual device sections were written including the testing information needed.

The following members agreed to review the various device sections and rewrite as required:

a. Reactors – Mike Sharp b. Ground Fault Neutralizers Klaus Pointner c. Grounding Transformers Don, Ayers, Fred Elliot, Sheldon Kennedy



d. Resistors – Sergio Panetta e. Combination Devices – Sergio Panetta

Input on all devices is required by January 15, 2012. The latest draft of the standard will be posted on the transformers Committee

website, and copies of the comments from the straw ballot will be mailed to all members.

10.4.6 TF on Tertiary/Stabilization WIndings – Enrique Betancourt, Chairman; Steve Snyder, Secretary The Group met at 8:00 AM on Monday, October 31, 2011 with 17 members and 55 guests present. The current Working Group membership stands at 34 members (2 of them Corresponding Members), therefore we did have a quorum. Seven (7) guests requested membership:

Benjamin Lopez Prolec GE Doug McCullough Maxima-Hyundai Emilio Morales EFACEC John K. John Virginia Transformer Corp. Robert F. Tillman Southern Co. Services Stephen Anthony PEPCO Van Nhi Nguyen Hydro Quebec

Next, an excerpt from the minutes of the Spring Meeting of WG “Continuous Revision of C57.12.00”, which included detailed report of our TF previous meeting, were reviewed by the Group and approved as representative of our previous activity. Old Business A. Survey on the new Clause for C57.12.00, related to thermal requirements for

Stabilizing Windings The group has been working for three years to resolve the subject of default kVA rating for stabilizing windings. A new clause was prepared by the group for inclusion in C57.12.00, and the following text was surveyed among the Performance Characteristics and Insulation Life Subcommittees prior to this meeting. “5.11.1.2 Thermal Rating for Stabilizing Windings (buried tertiary) In addition to the short circuit duty (see 7.1.4.4), stabilizing windings shall be designed to withstand the transient and continuous thermal duty as specified by the user and in accordance with the allowable temperature limits of 5.11.1. In the event no continuous thermal duty for the stabilizing winding can be established from the user’s specification, the manufacturer shall design the stabilizing winding considering the circulating current in that winding, resulting from a full single phase load in the largest main secondary winding. The manufacturer shall determine kVA rating for the stabilizing winding based on the transformer’s equivalent circuit for single phase loading condition. The manufacturer shall calculate values of average and hottest-spot temperatures for the stabilizing winding to verify compliance with allowable temperatures. Initial conditions for these calculations shall be based on the transformer operating at its maximum continuous rating, before switching to the loading conditions described above in the first or second paragraph, whichever is applicable.”



Note: “Transformer” is a general term for two winding transformers and autotransformers Forty (40) responses were received from the group surveyed, all of them “APPROVED”. Three of them included recommendations to further clarify the text. Based on those results, the work of this TF was deemed to be completed, and the new clause will be submitted for the next ballot of C57.12.00. New Business A. Formation of a new Working Group to develop an Application Guide for Tertiary

and Stabilizing Windings

Based on the strong interest expressed by the participants, the Task Force has requested to be upgraded to a Working Group, specifically to develop an application guide for tertiary and stabilizing windings. A first draft for the Title, Scope and Purpose of this new document was previously discussed and submitted for review of the Committee Officers. During this meeting, further adjustments were made: TITLE “Guide for the application of tertiary and stabilizing windings in power transformers.” SCOPE Liquid immersed power transformers, as covered by C57.12.00. Main focus on wye-wye connected transformers and autotransformers, provided with delta connected windings. PURPOSE To provide users with a conceptual framework and recommendations for specification, application and performance evaluation of tertiary and stabilizing windings. This guide will cover tertiary and stabilizing winding applications to Wind Farm Collector Transformers, Primary Distribution Transformers, and Network Tie Transformers and Autotransformers, with following remarks: We do not intend to address the general case of Multiwinding transformers; only the

specific case of Y-Y connected transformers or autotransformers. Double primary, or double secondary Y-Y transformers are included within the Scope. An initial, critical question to solve is if a Stabilizing Winding (or Tertiary Winding for the

same purpose) is required for an specific application of Y-Y connected transformers – Considering impact on, and user’s needs of zero sequence performance.

If a SW/TW is required, what parameters are recommended? Expecting a positive response from the Administrative Committee, the WG made decision to start preliminary work, and volunteers agreed to gather information on following subjects: 1. Survey on literature on Tertiary and Stabilizing Windings, identifying

recommendations applicable to transformers within the scope. 2. Investigation on system requirements associated to Zero Sequence performance of

transformers: Literature and Utility Practice 3. Investigation on impact of SWs and TWs regarding reported issues and transformers

performance (zero sequence flux effects)



10.4.7 TF on “Audible Sound Revision to Clause 13”, C57.12.90 – Ramsis Girgis, Chairman The TF met at 11:00 am on Monday, October 31, 2011 with a total of 63 in attendance, 18 members and 45 guests, 3 guests requested membershipe TF. First, the minutes of the San Diego meeting were approved as written. The chairman then presented an overview of the agreed – upon additions / changes to section 13 of C57.12.90. This was followed by a detailed review of the new proposed text in this section of the Standard. The 1st item discussed was “the correction for sound wall reflections’. The following comments / suggestions were made: The word ”adopted”, in the Note in the section referencing to IEC as the source of this

correction, should be replaced by the word “based upon”. The comment about the need for agreement between the purchaser and the

manufacturer on the suggested environmental corrections should be replaced by one where the agreement is needed if wanting to use an alternate method of correction. Subsequent to the meeting, the chairman did not think there is actually a need for such a statement as this is already implied and it also applies to all of the Standards requirements. This will be discussed again in the spring meeting.

Regarding the sufficiency of using 4 values for the Average Acoustic absorption coefficient in IEEE vs. 5 values in the revised IEC Standard, and 7 in the original IEC standard, a TF member suggested that IEC recommends measuring that coefficient. The chairman responded that the approximation involved in limiting the # of these values is small and actually much smaller than the impact of other factors in noise level measurement. Another member of this TF and the IEC WG suggested that the IEC solutions tend to be more theoretical while IEEE takes a more practical approach with very small errors.

A question whether there is a need to have a comment regarding the placement of the transformer under test in the test room and its impact on the sound reflection error, e.g. when placing the transformer in a corner of the test room. The chairman answered that the IEEE standard already requires a minimum of 3 m distance to the nearest wall.

The chairman mentioned that since the IEEE Standard will be allowing a maximum of 4 dB for the wall sound reflection correction “K”, that Figure 31, which includes the curve to use to obtain the value of “K”, will be adjusted to extend the vertical axis up to 4 dB.

Next item discussed was “load noise”. The following comments / suggestions were made: The chairman said that he intentionally used the paragraph on “Load loss measurement”

in section 9 of this Standard for load noise, in spite of the fact that the corresponding IEC paragraph reads better. This he did in order to minimize negative ballots. Editing of those sections may be made in a future revision.

A question as to why use the top rating and not the bottom rating of the transformer for measuring load noise; as Transformers are typically operated at their bottom rating at night when noise level limits are lowest. The chairman answered that load noise of transformers at their bottom rating (60 %) is typically very low (9 dB lower than at their top rating) and becomes hard to measure with sufficient accuracy at the factory. Hence, the chairman suggested changing the bottom boundary of the validity of the load noise measurement conversion range from 70 % to 60 %.



The chairman explained that the reason for using the load noise current conversion

range from 70 % to 130 % is to allow measuring load noise at 1. Higher current when load noise is too low to measure at full rated current 2. Lower current if test equipment does not allow testing at higher currents. High load

noise of the booth transformer can be one reason for that as it can not be corrected for in the “Sound Pressure Measuring method” since it is not part of the ambient noise.

The chairman suggested that the condition of needing to test the transformer for load noise at higher than rated current, because of higher ambient noise, needs to be added to the start of that paragraph.

A question whether the Load noise relationship to current is correct for both the ‘A – weighting’ as well as the full Octave, 1/3rd Octave, and Narrow – Band. The chairman answered “Yes” since Load noise is almost always dominated by the double power frequency component. Significant harmonics appear only when magnetic shielding used is overloaded. The same can happen when measuring the A – weighted level using the Sound Pressure method when the ambient has high level of higher harmonics. The Intensity Method is the preferred method for measuring load noise in general and in this case specifically.

Donald Chu, of ConEd, stated that the total noise level of a transformer, when in operation in the field, may not be at the rated load. The chairman understands the background of this statement and promised to explain it and discuss it with the TF at the Spring meeting when dealing with the subsection of section 13 dealing with the “Determination of the total noise level of a transformer”

Next item discussed was the “Sound Intensity Measuring Method”. The following comments / suggestions were made: Adding a statement that the alternative is to use the “Sound Pressure method” if the

condition, stated regarding the invalidity of the “Sound Intensity method”, occurred. Under those conditions, the “Sound Pressure method” would not be valid either but, at least, it results in penalizing the transformer manufacturer for not having proper environmental conditions.

Adding text that provides guidance to manufacturers on how to allow for proper environmental conditions. The chairman suggested adding such information in a separate noise testing Guide. However, subsequent to the meeting, Steve Antosz (PCS Chairman) reminded the chairman that the TF originally decided there was no need for a separate Guide, and that whatever guidance to be given should be included in section 13. The Chairman agreed but Steve suggested that we may think it through again whether there is a need of such a Guide.

Next item discussed was the new 2 m all around sound measuring contour for ONAF noise measurements. There were no comments on this item. Other items brought up and discussed: Jeewan Puri brought up the idea of correcting for near – field effects; which was

originally suggested by the chairman in the previous meeting of the TF in San Diego. The correction is to be made when measuring using the “Sound Pressure method”. Jeewan suggested a 2 dB correction, referring to earlier work done by the Chairman and his ABB team. The chairman supported this request and stated that this effect is typically between 1.0 and 1.5 dB; depending on the measuring contour. However, the chairman suggested that this idea is better revisited when discussing the section on the “Determination of the total noise level of a transformer”. This is because a change may



then be considered for the ONAN measuring contour in the revised section 13; as previously discussed.

A better title than “Transformer Operating Conditions” is needed.

Because of shortage of time, the final item; dealing with the “Determination of the total noise level of a transformer”, will be discussed at the spring meeting. The plan is to send the TF members and guests, shortly after the Boston meeting, the revised section 13 with modifications per the recommendations and decisions made at the Boston meeting for review and feedback. More reviews are planned for the period between now and the spring meeting, such that a final draft of the revised section 13 of C57.12.90 can be sent for Survey among the TF and PCS Subcommittee members after the spring meeting.

10.4.8 WG on Wind Trubine Generator Transformers. PC57.12.16, – David Buckmaster, Chairman; Vice Chair: Phil Hopkinson; Secretary:Scott Choinski The Task Force on Wind Power Transformers was called to order at 9:30 AM. This was the first meeting of the WG, which replaced a TF. Membership on the WG are those attending this first meeting and request membership, and those that responded to a call confirming membership earlier this year. There were 106 attendees, 57 members, 49 guests. The minutes from the final TF meeting held April 12, 2011, was accepted as written.

Chair Remarks

1. Introduction of WG board members Mr. Buckmaster introduced the officers of the WG Chairman: Dave Buckmaster Vice-chairman: Phil Hopkinson Secretary: Scott Choinski Saurabh Ghosh was appointed as an Alternate Vice-chairman It is intended to appoint a 2nd Vice-chairman from the IEC for joint work on the standard.

Paul Jarman, Chairman of IEC TC14, reported that IEC 60076-16 was published in August. TC14 will send a notice to all National Committees seeking approval for an immediate revision to the document, which is unusual for an IEC standard. The justification is a joint revision with IEEE.

Paul Jarman and Dave Buckmaster will meet after this meeting to review IEC 60076-16 and discuss what is missing in the document from the IEEE perspective. Dave Buckmaster volunteered to prepare a list of these issues to submit to Paul Jarman by Christmas.

2. Discussion of Name, Purpose & Scope

Reviewed the title, purpose and scope of the proposed document. This is what is on the PAR, and it is on the NESCOM agenda. A 6 month delay has been requested for PAR approval to allow the IEC to go through its process to approve starting a revision to IEC 60076-16. The scope had been modified to change 38 kV to 34.5 kV.

Title:Standard requirements for Wind Turbine Generator Transformers



Scope:This standard establishes requirements for Liquid Immersed, or Dry Type transformers with at least one set of terminals rated ≤ 34.5 kV with a capacity rating ≤ 100000kVA suitable for Step-Up operation to be used to transform the voltage from the Wind Turbine generator to the system voltage of the collector grid.

Purpose:The purpose is to enable manufacturers and users in specifying, designing, and manufacturing transformers used for Wind Turbine Generator duty.

3. Key dates in the PAR

Expect final draft August 2014 Project completion May 2015

4. Brief discussion of IEC 60076-16

Published by IEC August 2011. Most WG members have not seen the published document yet.

Jodi Haasz to request a copy for WG use. It will be placed on the Transformer Committee website in a password protected area. Reviewed the copyright rules for the IEC document. Contact Chair or Secretary for access to the document.

5. Working Group collaboration with IEC for a dual logo document

It is intended for a joint revision of IEC 60076-16 with IEC. If the IEC does not agree to a revision, then this WG will move on with a stand-alone document. The IEC document would be used as a starting point.

An adoption of the IEC document by the US may not be a good option. There are many issues to address in the IEC document for it to be acceptable to IEEE.

6. What other sub-committees or working groups may be affected by this group’s work

Insulating Fluids (C57.104)

Tap Changers (C57.131)

Bushings (C57.19)

Others? No other committees were identified.

C. NFPA 70E Compliance for Arc Flash – Dave Buckmaster volunteered.

D. TF to study failure mechanisms. May not be warranted at this time.

E. Stress enhancement points/gas analysis – Ray Bartnikas to submit a proposal

F. Others – No other tasks identified



10.4.9 WG on “Guide for the Application and Interpretation of Frequency Response Analysis

for Oil Immersed Transformers”, PC57.149 – Chairman; Charles Sweetser WG PC57.149 met for the development of the Frequency Response Analysis (FRA) Guide in Boston, MA on October 31, 2011 at 11:00 AM. There were 96 people in attendance. Only 14 of our 32 members were in attendance, and a quorum was NOT established. The first order of business was to show the slides regarding patents, assurances and inappropriate behavior.The minutes from the Houston, TX 2010 and Toronto meetings were not approved. This will be addressed at the next meeting. This meeting focused on the ballot results of the FRA Guide. The ballot closed on September 10, 2011. The ballot results are as follows:

Number of Ballots: 136 Response Rate: 83% Approval Rate: 88% Abstention Rate: 7%

The ballot produced 266 comments. The breakdown is as follows:

Category Must be Satisfied

# Comments

Editorial YES 38 General YES 5 Technical YES 50 TOTAL 93 Editorial NO 115 General NO 32 Technical NO 26 TOTAL 173

A ballot resolution group was established. The following members accepted the ballot resolution responsibilities for following categories:

Category Must be Satisfied

WG Member

Editorial YES Charles Sweetser General YES Peter Werelius/Mario Locarno Technical YES Peter Werelius/Mario Locarno Editorial NO Charles Sweetser General NO Peter Balma Technical NO Kirk Robbins/Hemchandra Shertukde

The common ballot results were reviewed; 4 topics were identified as being most difficult: 1.) Frequency Range covered in guide, but not specified 2.) Dynamic Range, Resolution and Accuracy not being specified 3.) Applied Voltage not being specified 4.) Statements related to insulation degradation and clamping pressure. The balloter stated

that these issues are outside the diagnostic ability of FRA. The ballot resolution group has been directed to solve these issues.




10.4.10 Special Reports Status of Semiconductor Rectifier Transformers C57.18.10 S. Kennedy

The Task Force has been retired from an active Task Force to allow more meeting room for Working Groups with PAR’s. The Chair sent the final meeting minutes of the Toronto meeting to the membership. This TF was to work on a few special items while we still have the group together. We have a proposal for a clause on electrostatic ground shields. We have decided on a way forward for a method to show phase shifted secondary windings with multi-pulse secondary windings such as 18 pulse, 24 pulse, 36 pulse, 48 pulse and 54 pulse are becoming a great part of the motor drive transformer applications, as well as higher current rectifier transformers. The Task Force decided to just propose general discussions of phase shifting windings and not give any of the exact phase shifts that are being used in industry. This seemed the best way to accomplish this. There was a discussion about determining the losses in specific regions due to harmonics. IEC has tackled this subject already in an Annex and this should be done in our next revision, as well. An example of the response of the windings to the 5th, 7th, 11th, and 13th harmonic, for instance, is much different than the fundamental current when we examine the leakage fields and loss densities with finite element methods. This concluded the specific items the Task Force was commissioned to accomplish. The Chair will try to do continued work offline to help do some organization of the standard to get it into the proper format of the styles manual. The chair has asked any members who would like to volunteer to assist in this effort to contact him.

10.5.1.6 WORKING GROUP FOR DEVELOPMENT OF PC57.131, STANDARD

REQUIREMENTS FOR TAP CHANGERS - William Henning, Chairman The Working Group on Tap Changer Performance met on Monday, October 31, 2011 at 1:45 pm with 9 members and 26 guests present. Introductions were made, and the minutes were approved. The chairman gave a report on Recirculation 3, Draft 1.8. As of November 2, the status was: 97 Affirmative Votes 1 Negative Vote 3 Abstentions 98% Affirmative The recirculation closes on November 7. Previous drafts have produced negative votes because of the warning label to be affixed to de-energized tap changers, warning not to operate the tap changer while the transformer is energized or under load. Some discussion of the warning label took place at the meeting. Jim Harlow proposed a longer version of the warning message that not only says what not to do but includes the consequences of improper action and a statement of proper action. It also came up that, perhaps, we should not use the word warning and not show the message as a figure. It was acknowledged that the subject

requires more study. It was the consensus of those present that the Draft 1.8 submittal to RevCom should not be delayed for this study. 10.5.1.6 WORKING GROUP FOR REVISION OF C57.135, GUIDE FOR THE

APPLICATION, SPECIFICATION AND TESTING OF PHASE-SHIFTING TRANSFORMERS – Jin Sim, Chairman

No meeting was held. The guide was published this year. This document was adopted by IEC and the revision was accepted as well. A motion was offered to submit a PAR to create a phase shifting transformer standard, leaving this guide “as-is”. This would be a joint project between IEEE and IEC. It was voted to form the working group to develop a phase shifting standard. 10.5.1.6 WORKING GROUP FOR THE REVISION OF PC57.140, GUIDE FOR

EVALUATION AND RECONDITIONING OF LIQUID-IMMERSED POWER TRANSFORMERS – Roland James, Chairman

Chair Rowland James called the WG meeting to order at 1:50 pm November 1, 2011. Vice Chair Paul Boman and WG Secretary Saurabh Ghosh were also present. There were 31 members and 42 guests with 13 guests requesting membership. The Working Group did not have a quorum and thus no official resolution could be passed. Vice Chair Paul Boman gave a presentation on CIGRE Working Group A2.34 – “Guide for Transformer Maintenance”. Discussions on the presentations led to topics on “Asset Management”, minimum amount of maintenance with maximum returns, “Optimization on maintenance practices”, “best practice and common practice”, “condition assessment”, DGA and in service oil testing. There was a discussion on load levels while performing infrared testing as described in sub clause 5.7”Infrared Inspection”. It was proposed that transformers be loaded higher than 40% of maximum nameplate rating. One argument against this was that transformers may not normally operate at theis level and increasing load may not be practical. Further study of this matter will ensue. The chair requested volunteers for sections of the guide not yet reviewed. He also requested the working group to review section six “Condition assessment and reconditioning” with intent to determine if this section is philosophically meeting the purpose of this guide. The meeting was adjourned at 3:01 p.m.

There were 13 of 38 members present with 45 guests. A quorum was not achieved. New membership requests will not be entertained as the Guide has already gone out for ballot. Agenda:

1. Introductions/Member Roll Call 2. Approval of Spring 2010, Houston, Texas Minutes 3. Ballot Status and steps ahead 4. Review of Contributor List 5. Adjourn

Approval of minutes from the Spring 2010, Houston, Texas meeting could not be done due to a lack of quorum.

Greg Anderson gave a short explanation to new people present what the purpose of the guide is and where we are with the document. The document was sent out for ballot September 23 and closed October 23. There were 111 balloters. There were 102 votes received (91%). There were 86 affirmative votes (94%) and 5 negative ballots with comments. There were 11 abstention votes (10%); 2 of these for conflict of interest, 6 for lack of experience and 3 for lack of time.

Greg indicated that approximately 80% of the comments are editorial and will be corrected. Members were asked to volunteer to serve on a Ballot Resolution Group to resolve the remaining technical comments received from the ballot. The following members volunteered to help with this effort: Dave Wallach, Joe Watson, Martin Heathcote, Bill Darovny, and Bruce Fairris along with Greg Anderson, Ewald Schweiger, and Susan McNelly. Joe Watson asked about the status of the PAR. The PAR was set to expire at the end of 2011. A request to extend the PAR for one additional year was submitted. Some of the comments received were regarding field testing. Some tests are considered transportation related testing such as dew point, core ground, and SFRA tests. Field acceptance testing does not belong in the transportation guide. Greg proposed a demarcation point for going from the transportation guide to the installation guide would be at the point the transformer is offloaded onto the foundation. There is also a demarcation point for insurance when the unit is passed from one carrier to another or on delivery. A comment was made by Fred Elliott that it would be appropriate to at least include a list of the field testing normally done as part of an acceptance process with reference to the installation guide for more details. Joe Foldi commented that he thinks this is a very important document. However, he indicated that at a minimum some limits or suggested g-force values should be provided for truck, rail, and ocean g-force impact shipments. Greg indicated that we cannot provide discrete limits since this is a guide, not a standard but that we want to educate people on this issue. A comment was made that Cigre is also working on a transportation guide. Greg indicated that he would like to work with them on future revisions to share ideas and possibly exchange information. Meeting was adjourned at 8:55am.

10.5.1.11 WORKING GROUP FOR DEVELOPMENT OF PC57.156, GUIDE FOR

TRANSFORMER TANK RUPTURE MITIGATION OF LIQUID-IMMERSED POWER TRANSFORMERS AND REACTORS– Peter Zhao, Chairman

The first official meeting of the Working Group for the Guide for Tank Rupture Mitigation convened Monday morning at 11:00am. Chairman Peter Zhao presided. Attendees were reminded that t hey had ea ch answered a q uestion regarding patent policy as part of registrati on, and therefore patent issues will no longer be addressed during the meetings. Attendance was 62 (16 members, 46 guests, with 12 guests requesting membership). Chairman Zhao provided introductory remarks and previewed the agenda to be covered for the meeting.

- The PAR for the guide was ap proved by IEEE shortly after the Spring 20 11 meeting. A first draft of the guide has been completed for revi ew. The PAR schedule is for draft completion by 201 4. Attendees encouraged to review the draft on line and submit questions and co mments to the chair before S pring meeting in Nashville.

- Attendees were informed that the dra ft of the guide is posted on the IEEE website, and that they should review it and provide questions/issues bac k to Chairman Zhao before the Spring 2012 meeting, for discussion at that meeting.

- It was als o explained that any one desiring to bec ome members of this new working group should so indicat e on rosters, which were being c irculated during the meeting.

A very informative presentation of one supp lier’s design of a modern isolation barrier (fire wall) system was provided. Martin Heathcoat provided progress of his effort to define available arc-energy levels for Generator Step-Up transformers (Table 4) . He has received a discussion of issues/principles involved, but has not yet translated the information into actual numbers for the table. A discussion of Figure 5 (Dynamic Load Factor) ensued. Izyaslav Polishchuk cautioned that the data from which this figure was generated is preliminary and that we must be careful before publishing it. The remainder of the meeting c onsisted of a discussion, item by item, of Section 7.1 “Design Review” with the following significant comments/observations:

- The working group should reme mber that we will not prevent the internal fault. Our objective is to prevent or mitigate the rupture from the fault.

- There has been much good information generated already. As we move forward we should be carefu l to not b ecome the basis for court actions against a manufacturer or user for not complying with our guidelines.

- Mark Scarbough stated that he is aware of an effort to classify transformer tanks as pressure vessels – requiring them to be pressure tested. It was suggested that the limit of consider ation for pressure vessels is somewhere above 15 psig capability.

- It was strongly recom mended that we prov ide a section in the guide to addr ess the issue of whether pressure testing is to be required to validat e capability to withstand an internal fault.

Meeting was adjourned at 12:15pm. 10.5.1.12 WORKING GROUP FOR DEVELOPMENT OF PC57.157, GUIDE FOR

CONDUCTING FUNCTIONAL LIFE TESTS FOR DE-ENERGIZED TAP CHANGER CONTACTS – Phil Hopkinson, Chairman

The Working Group on Life Tests, De-energized Tap Changers was called to order at 8:00 AM on November 1, 2011. This was the first meeting of the WG, which replaced a TF that had been in existence for many years. Membership on the WG are those attending this first meeting and request membership. There were 54 attendees, 25 members, and 29 guests. A quorum was present.

Reviewed the Agenda for the meeting, and the Minutes from the April 12, 2011, meeting in San Diego, California, were approved. 1. A PAR had been submitted. Need to make sure that the title of the document

does not conflict with the scope of the PAR. A modification to the PAR may be required. Chair may need authority from the WG to make changes to the PAR to answer possible questions from NESCOM (such as “what is the meaning of infrequent”).

2. Review of Draft 1 of the Guide provided by Larry Dix. Title of document is Draft Guide for Conducting Functional Life Tests for De-Energized Tap-changer Contacts WG proposed modifying title to: Draft Guide for Conducting Functional Life Tests for Infrequently Operated Switches Used within Liquid Filled Transformers Motion: Keep title as it is. Motion was approved 14-3 Reviewed the purpose of the document, and it was acceptable. Normative references need to be specifically cited in the document. If not specifically cited, then it belongs in the bibliography. It was also recommended to not cite the date for the normative references if possible. It limits you to that edition of the document, while the latest edition applies if the date is not cited. Larry Dix to propose a new scope. WG members may suggest changes. Proposals should be sent to Larry Dix and Phil Hopkinson.

3. New Business

There was no new business.

The meeting adjourned at 9:15 AM. 10.5.1.13 WORKING GROUP FOR REVISION OF IEEE STD 638-1992, IEEE

STANDARD FOR QUALIFICATION OF CLASS 1E TRANSFORMERS FOR NUCLEAR POWER GENERATING STATIONS – Craig Swinderman, Chairman

The Working Group for revision of IEEE 638 did not meet during the Boston session in November 2011. The revision of the document has been completed, and Draft 8 of the document has been submitted for Mandatory Editorial Coordination. An Invitation Request to form a Ballot Group has been submitted, and the ballot group should be formed within 30 days. Members from Power Engineering Society Transformers Committee and the Nuclear Power Engineering Committee have been invited. A 1-year PAR Extension request has been submitted to NESCOM for the Standards Board December agenda, in order to allow time to complete the balloting process and address any comments received in order to complete the work for submitting the standard. 10.5.1.14 TASK FORCE FOR DVP-GRID TRANSFORMERS, WHITE PAPER–

Hemchandra Shertukde, Chairman The meeting was convened with 12 members (out of current 23 members - quorum) and 18 guests present. 6 guests requested membership. The IEEE patent recommendations were addressed; no patents or patent claims were identified in relation to the work of TF. Old Business San Diego’s meeting minutes were approved. New business - The TF Chair reviewed the e-mail from the PT Committee Chairman T. Lundquist:

after PT SC meeting in Boston, TF will be dissolved the work is completed as the assignment is accomplished the Chair of PT SC has the request to determine which SC a WG shall be

assigned Bill Bartley has a copy of the PAR and it’s on hold until SC is determined Bill Chiu has a copy of the proposed paper for review to determine, if it may be

published as a result of the TF work - B. Chiu commented that he is not completely sure that the questions assigned to the TF were completely and clear answered, specifically – what are the issues that are not addressed in other standards. This initiated a discussion.

S. Levin reviewed the Conclusion Chapter of the Position paper for the group. He also described the TF poll results, confirming that TF recommended to continue work towards the Guide in the WG format.

D. Ayers commented that the recommendations on the resolution of the specific technical aspects may have been in other standards, but users may not aware about those aspects at all. Guide would describe the operating conditions and points of attention in one document.

Jin Sim questioned whether TF concluded their work. He referred to C57.12.00 (unusual service conditions) and commented that he thinks that all specific issues of DPV Grid Transformers can be addressed within existing standards.

E. Betancourt – different players (transformer and inverter OEM, owners and end users) involved in the process. Practically, there is no much support shown by inverter manufacturers. The specific issues with large inverters may include, inrush current, electrostatic shielding, etc.). Document addressing the typical operational environment can be helpful.

J. Watson informed PT SC concluded that TF completed the assignment. The decision on the publishing the TF work paper is a different question.

K. Yule commented that, as a buyer of the systems, he recognized that standard commodity transformer approach may not be appropriate for all cases (wind industry example), but he would not like to see that inverter industry drives the solution that require very sophisticated and expensive transformers.

S. Schroeder reminded that it maybe better to try addressing the specific constrains of the application on the early stages, then start working on them after problem occurred (again, wind industry examples)

- PAR and WG.

S. Levin reviewed the PAR document on the User’s Guide submitted to PT SC. B. Chiu – in order to decide on the next steps in this work, the PAR shall have

sponsor. H. Shertukde – can new SC of “special transformers” be created? B. Chiu had the motion to request TF Chair to submit PAR to the Performance

Characteristic SC as a new business. It was seconded and approved with 11 members approved and 1 abstained.

With no new business the TF was disbanded. Meeting adjourned at 12:00 AM. 10.5.3 OLD BUSINESS None. 10.5.3 NEW BUSINESS

a. The task force for DPV-Grid transformers has completed their work and the task force was dissolved.

b. Mike Lau will be Chair for the WG for revision of C57.93 “IEEE Guide for Installation of Liquid-Immersed Power Transformers” Revision PAR will be applied for after January 1, 2012.

10.5.4 STATUS OF “INACTIVE” GROUPS WORKING GROUP FOR THE REVISION OF C57.93, INSTALLATION OF LIQUID-FILLED TRANSFORMERS - Michael Lau, Chairman This group is not meeting; major work on this document is complete; waiting for publishing. TASK FORCE FOR WIND FARM TRANSFORMERS – Joe Watson, Chairman Work of this group is complete; the task force is inactive. TASK FORCE FOR EVALUATING THE NEEDS OF TRANSFORMERS USED WITH SVC – Peter Zhao, Chairman Fall 2009 - The work of this task force is concluded. A report was issued and it is being considered if an educational paper should be published. TASK FORCE FOR WIND GENERATOR STEP-UP TRANSFORMERS – David Buckmaster, Chairman This task force was moved to Performance Characteristics Subcommittee. WORKING GROUP FOR REVISION OF C57.12.10, STANDARD REQUIREMENTS FOR LIQUID IMMERSED POWER TRANSFORMERS – Gary Hoffman, Chairman The standard was published.

10.6 Underground Transformers and Network Protectors – Carl G.

Niemann (Chair), Dan Mulkey (Vice-Chair)

Meeting Minutes – November 2, 2011

Introduction/Attendance The Underground Transformers and Network Protectors Subcommittee met on Wednesday, November 2, 2011, in the Pacific AB room of the Renaissance Waterfront Hotel in Boston, MA California, at 11:00 AM with 8 members and 9 guests present. One guest requested membership.

Approval of Minutes The minutes of the April 2011, meeting in San Diego, CA were approved as submitted.

Membership There are 12 members, and attendance by 7 is required for a quorum, which was achieved for this meeting.

Chairman’s Remarks The chair provided a summary of the Administrative activity.

Working Group Reports 10.6.1.1 Underground Single Phase Transformers (C57.12.23) – A. Traut, Chairman

The WG did not meet. The document was published in April 2009 and is valid until 12/31/2014. After the TF on Tank Pressure Coordination lead by Carlos Gaytan, concludes this standard will need to be revised.

10.6.1.2 Three-Phase Underground-Type Transformers (C57.12.24) – Giuseppe Termini, Chairman

1. The Chairman welcomed members and guests to the meeting which was called to order at 8:00 a.m. in the Caspian Room of the Renaissance Boston Waterfront on October 31, 2011. George Payerle acted as the recording secretary. The Chairman explained that members need to attend 3 consecutive meetings in order to apply and become a voting m ember of the working group (WG). The expectation is that the g uests and members should take an activ e participation in the proceedings of the working group.

2. An agenda was presented and introductions were made. The m eeting was attended by 7

members and 19 guests and there w as quorum for this m eeting. Minutes from the previous meeting in San Diego on April 11, 2011 were revi ewed and approved. It was noted that since patent disclosure will now be a part of the registration process, the subject does not need to be discussed at the meetings.

3. The Chairman previously submitted a PAR to star t the process of the st andard revision. The

PAR has not yet b een approved. Meanwhile, the working group proceeded in discussing future changes to the s tandard. Three areas were dis cussed as po tential topics for future inclusion in the standard: a. fusing, b. pressure relief valve and c. tank material and corrosion.

a. Fusing - The current standard does not recommend a fuse system . There was a

discussion of adding cu rrent limiting fuses in the stand ard as a way to m itigate the

possibility of a catastrophic failure (tank rupture). It was noted that Dominion Virginia did a study in the 60s and ca me out with speci fications that require transformers to be equipped with current lim iting or weak link fuses. It was pointed out that current limiting fuses help with high current short duration faults but the faults that sometimes cause tank failures are the low current faults with long duration.

b. Pressure relief valve (P RV) - It was noted that there is a task force looking at a standard regarding tank ruptur e. There was discussion as to whether work from that group should be incorporated into our standard. The Dom inion study m entioned previously also recommended that there was a need for pressure relief devices and a need to define tank withstand. Ju stin Pezzin will attend the TF for Tank Pressu re Coordination and George Payerle will at tend the WG for Tank Rupture & Mitiga tion C57.156 at these meetings. They will report back at the next meeting.

c. It was also noted that P RVs on submersible transformers need to be able to withsta nd the same stringent requirements as the tr ansformer itself. Som e utilities do not u se PRVs on submersible transformers. The standard allows for the installation of a PRV but it does not provide any design or operational requirements.

4. Tank material and corrosion - The last issue discussed was how tank corrosion requirem ents

are handled by the end-users. It was mentioned that one of th e most common failure mode of submersible transformers failure is corrosion. The need to include specific stainless steel material grades for the tank construction was discussed.

5. It was decided to create a su rvey to poll end-users of subm ersible transformers on the three

topics discussed above. Som e of the users that were identified for this poll included PECO Energy, Hydro Quebec, Dom inion Virginia, Georgia Power and PG&E. Bill W immer volunteered to expand the users’ list to include an intranet users group run by Bob Landman.

Possible questions to the end-users to be included in the survey are:

Do you use PRVs on submersible transformers? What concerns do you have about PRVs and do you have data supporting these

concerns? What type of fusing do you specify on submersibles? What concerns do you have about the fusing and do you have data supporting these

concerns? What tank materials do you specify for submersibles? Stainless steel 304L, 316L, 400

series, or other? Do you have install cathodic protection inside manholes where transformers are

located?

6. The Chairman will prepare the initial survey and will send it to Chris Sulliv an, Said Hachichi and Bill Wimmer to be finalized prior to sending it to the end-users group.

7. The meeting was adjourned at 9:15 a.m. with the next meeting set for Nashville, TN on March 12, 2012.

10.6.1.3 Liquid Filled Secondary Network Transformers (C57.12.40) – Brian Klaponski, Chairman

1. The WG met on Monday, October 31, 2011 at 09:30 am with 11 members and 7 guests. The minutes of the April 11, 2011 meeting in San Diego, CA were reviewed and approved. Steve Schroeder made a motion to approve the Meeting Minutes and Bill Wimmer seconded the motion and they were approved.

2. The meeting consisted of the review of the balloting and re-circulation process of the standard.

The chairman stated that a ballot resolution committee, comprised of the chairman, Larry Dix, and Giuseppe Termini was formed to resolve comments received during balloting. The comments were just associated with affirmative ballots. There were no negative ballots on the original ballot nor on the Recirc ballot. The ballot resolution committee was able to resolve or dispose of all comments received during the balloting process and then the Recir ballot in early Oct 2011 had no negatives and no comments.

3. The balloted standard was sent to the IEEE RevCom committee for review and approval during their Dec 6/11 meeting. Once RevCom approves the standard, then the next day it goes to the Standards Committee for approval. It is anticipated that the standard will be published early in 2012.

4. The comments that weren’t accepted along with other comments received earlier from John Rosetti will be considered for the next standard revision.

5. The approval of the standard marks a significant milestone because this was the first comprehensive revision of the standard since the mid 90’s.

6. The meeting was adjourned at 10:30 am with the next meeting set for Nashville, TN, in March 2012.

10.6.1.4 Secondary Network Protectors (C57.12.44) – Bill Wimmer, Chairman 1. The meeting was called to order and a review was made of the members present. Introductions

were made of all members and guests present. 2. The San Diego minutes of April 11th, 2011 were reviewed and approved (Niemann/Faulkner). 3. Discussion of Changes to the Document

A. It was noted that it is acceptable to lock in a specific reference date for the standard references or not put any date. In the case of the latter, IEEE will supply the current approved standard date. B. Klaponski

B. References to 12.40 are ok to leave as current due to only one reference regarding throat standard which has and will not change.

C. C37.108 -- must come out of informative references and placed in document. Must be moved into informative annex. And date removed for reference.

D. Clause 10.5.20 on Page 23 discussions. i. Lead back to original phase in standard except with the addition of the word

“properly”: “The operating mechanism and relay cases shall be properly grounded to the enclosure through the removable breaker. “

E. 5.2.3.3. Micro-Ohm i. Lead sentence added in Design Type Section:

If the manufacturer can demonstrate that the micro ohm values recorded will not exceed temp in table one. A additional heat run after type testing’s will not be required. Further discussions will continue on this topic with an email ballot on the final wordings.

4. The WG adjourned at 12:15 pm with the next meeting in Nashville, TN on March, 2012.

10.6.1.5 Ventilated Dry-Type Network Transformers (C57.12.57) 1. The WG was not scheduled to meet.

Old Business

1. Brian Klaponski – 10 years is a long time. You can loose a lot of knowledge in that time frame Standard revisions should be done on a 5 year time cycle to avoid that.

2. Brian Klaponski has volunteered to visit IEEE headquarters with Ed Smith to explain the issues on moving a standard project through the system when you only use it every four or five years

New Business 1. Patent Issue – it is great to see the patents dealt with during the Registration process. That is a

great time saver in our meetings all week. Now we need to finish the patent issue. What is the Transformers Committee going to do with the patents that are declared. Also what is required is a method to make all the patent declarations and any LOA’s transparent to all Transformers Committee members.

2. ANSI – where has the ANSI designation gone is IEEE published standards since about 2006. It is now buried in a full page of descriptive text on about page 3 of recent documents that IEEE published.

3. The part of the Standards development process that is administrative (PAR, balloting, etc)- this process needs stream lining from the Transformers Committee standpoint. WG Chairs are left to sort through an administrative process to satisfy IEEE needs that is far too difficult and time consuming. WG chairs need to concentrate on CONTENT and not administrative protocol.

Future Meetings

The Spring 2012 meeting will be on March 11-15, 2012 in Nashville, Tennessee.

MINUTES OF MEETING BUSHING SUBCOMMITTEE

OF THE IEEE/PES TRANSFORMER COMMITTEE

Boston, MA November 2, 2011

10.7 Bushing Subcommittee – Peter Zhao, Chair; Eric Weatherbee, Secretary.

10.7.1 Introduction/Attendance Chair opened the meeting at 9:30 AM and welcomed the members and guests. A quorum was formed by confirmation of member attendance. There were 87 attendees with 20 members and 67 guests present. Patent policy was addressed in the meeting and no patent conflict was reported. 10.7.2 Approval of Minutes of Last Meeting The minutes of last meeting in San Diego, CA were approved as written.

10.7.3 Chairman’s Remarks

a) Next meeting will be held in Nashville, TN on March 11

th through March 15

th hosted by

Baron USA, INC. b) Discussed changes to the meeting format c) Reviewed the current status of all bushing committees and future dates. Including the newly

approved PAR for the GSU Bushing Working Group.

10.7.4 Working Group (WG) and Task Force (TF) Reports

10.7.4.1 WG - Revision of C57.19.00 - Keith Ellis, Chair

Reaffirmed C57.19.00-2004 – New expiration date is Dec. 31, 2015

10.7.4.2 WG - Revision of C57.19.01 – Arturo Del Rio, Chair The working group met on Tuesday November 1, 2011, at 9:30 am with a total of 32 participants. Of those, 12 members and 20 guests with 5 guests requesting membership.

� The meeting was opened with introductions and the presentation and review of the minutes from the previous meeting.

� The first topic in the agenda was the review of the scope of the standard to avoid conflict with the work being done on the standardization of GSU bushings for use in bus-enclosures. The proposed new scope includes the 150 kV BIL level, limits the rated continuous current to 5,000 amps or less, adds the “for use in free-air” statement and eliminates the reference to an obsolete standard. Members of the working group are encouraged to send comments or propose changes with a brief justification for further discussion.

2

� Five topics related to comments submitted during the balloting process of the standard in 2000 and the subsequent reaffirmation in 2005 were discussed:

1. Add 25 kV, 115 kV and 161 kV bushings to preferred ratings.

2. We should take all listed styles though 230 kV to 5,000 amps as we are seeing larger and larger power transformers being purchased.

3. It is time to dump the breaker plates on HV bushings. By replacing the breaker plate with a smaller connection plate with an integral 2-hole or 4-hole spade.

4. The TBI cantilever requirements should be put back because the bushing manufactures did not change the designs to reduce the bushing mechanical strength in order to “meet” the lowered requirement specified in the 2000 version.

5. Review BIL, and Hipot test requirements for bushings for all voltage classes, to be more in line with other existing standards (IEC, CSA).

Each one of these items needs to be put in tabular form for comparison and better understanding and illustration in future discussions.

� Meeting was adjourned at 10:30 am.

� Any members of the Bushings Subcommittee are welcome to join this new WG and participate in the revision of the Standard.

Minutes by: Arturo Del Rio, WG Chair. e-mail: [email protected] Boston, November 1, 2011.

• SC36A MT5 is working with The IEEE Bushing subcommittee with a joint working group to produce a dual logo document. Three meetings have been held, in Lombard (Fall 2009), Houston (Spring 2010) and Toronto (Fall 2010). Work has proceeded by email to avoid a meeting in Europe. Committee draft (CD) was circulated in May 2001 for comment to IEC and IEEE members. Comments have been received from

• both groups, IEC comments were discussed in Melbourne. Most comments from IEEE concerned the presentation of the document in IEC format with mainly IEC references. IEC Central Office and IEEE Program Manager have been asked for guidance on the agreed method for presentation of Dual-Logo standards. The document will go to IEEE ballot.

• No meeting was held in Boston pending completion of the comments.

• It is hoped to discuss comments at the Nashville meeting. 10.7.4.6 IEC Bushing Standards Activity - John Graham IEC Meetings The IEC bushing committee SC36A met during the IEC General Session in Melbourne, Australia on October 21st 2011. Work on the following documents was discussed. IEC60137 “Insulated Bushings for Alternating Voltages above 1000V” Edition 6 was published in July 2008; at the Sao Paulo meeting in 2008 the maintenance date for IEC60137 is set at 2011 and work started in April 2011 on a new revision. The main purpose is to include test values for UHV bushings (above 800kV rating) in line with the latest edition of

4

IEC60071-1: Insulation Co-ordination. During the revision the working group will address inconsistencies in the test method for temperature rise of external connections – this inconsistency also exists in IEEE C57.19.00. Also changes to the calculation of creepage distance in line with IEC60815 will be included. In May 2011 a draft for comment (DC) was circulated and comments received were discussed in Melbourne. The main comments concerned the need for alignment with the proposed revision to the transformer testing specification IEC60076-3, this may include increase the range of application of Switching Impulse tests. Other Work – The stability dates of other standards have been extended. IEC61463 Seismic qualification of bushings – a call for experts will be made to form a new maintenance committee. IEC61464 Dissolved gas analysis of oil impregnated paper bushings – no work planned until IEC TC10 completes revision of the main DGA standard IEC60599. The bushing subcommittee will be responsible for interpretation of analysis with TC10 responsible for methods. CENELEC The European standards organization has recently published revisions of bushing standards for low voltage bushings. EN50180 – Bushings above 1kV up to 52kV and from 250A to 3.15kA for liquid filled transformers. EN50386 – Bushings up to 1kV and from 250A to 5kA for liquid filled transformers. Chairman SC36A Chairman Lars Johansson (Sweden) will retire in 2012 after 9 years in the role. The Italian National Committee proposes to nominate John Graham (UK) as successor. 10.7.4.7 IEEE 693 - Interaction of Bushings and Transformers during Seismic Events – Lonnie Elder Eric Weatherbee gave a brief update on the progress and transition the working group is currently undergoing in regards to the bushing/transformer interaction. Discussions ensued in regards to what is considered a failure of a qualified bushing. 10.7.4.8 Task Force on PD Measurement on Bushings & CTs - Thang Hochanh, Chair The Chair asked for member comments on the materials that were presented during the meeting. 10.7.5 Unfinished Business – none 10.7.6 New Business - none

10.7.7 Presentation – General Considerations of Bushings Applied in Metal Enclosed Bus by J D Brafa (available online)

Before the presentation started Peter Zhao discussed the history and needs leading up to the decision to start moving forward with the creation of GSU working group. He stressed the importance of end user participation as well as both bushing and transformer manufacturers.

Presentation summary: - Major differences between bushings applied in a metal enclosed bus and standard

bushings as defined by IEEE C57.19.01

5

- What can happen to a bushing applied to but not designed for this type of

environment.

- Obstacles the GSU committee will have to overcome in order to finalize the GSU

bushing standard since it is a dimensional standard.

Lengthy discussion took place after the presentation was completed; including dimensional considerations for new and replacement bushings. A member of C57.116 (guide for transformers directly connected to generators) who mentioned their group is also looking at these same issues. The Chair suggested the new GSU working group chair will get in contact with the chair of C57.116 to share information and resources.

10.7.8 Adjournment

The meeting adjourned at 10:45 PM. Minutes submitted respectively by, Eric Weatherbee Secretary Bushing Subcommittee

10.8 Dry Type Transformers SC Chair Charles Johnson

Acting Secretary Casey Ballard

10.8.1 Introductions and Approval of Minutes

The Dry Type Transformer Committee meeting began at 1:34pm Wednesday, November 2, 2011 in the Pacific “FGH” rooms of the Renaissance Waterfront Hotel In Boston Massachusetts with introductions of members and guests. There were 15 members (out of 29 on the roster, therefore a quorum was reached with 51.7%) and 15 guests present. The m eeting minutes for the San Diego, CA meeting (Motion: Phil Hopkinson Second: Mark Gromlovits) were approved. The Chair asked if anyone knew of any patent related issues; none were identified.

10.8.2 Working Group/Task Force Reports

The next order of business was the presentation of the reports of the various working groups and task forces. See the following sections for the individual reports:

10.8.2.1 WG PC57.12.01 - Dry Type General Requirements Chair Tim Holdway Secretary Casey Ballard

The working group met in the Pacific C Room of the Renaissance Boston Waterfront Hotel

The meeting was called to order at 11:03 AM by Chairman Tim Holdway.

The meeting was convened with fourteen (14) members (out of 21 – therefore a quorum was reached with 67% attending) and 12 guests present with 1 requesting membership.

The minutes of the San Diego April 11, 2011 meeting were approved. Motion: Mark Gromlovits Second: Chuck Johnson

Attendees were asked if they knew of any patents that may be related to the work of this working group. No patents or patent claims pertinent to C57.12.01 were identified by working group members.

Old business

Nameplate Tim Holdway stated that no nameplate requirements will be placed into C57.12.01 unless the DOE or NEMA specifically requires them. Any manufacturer that wishes to include text relating to DOE is free to do so.

Partial Discharge Rick Marek presented a power point using data provided from several manufacturers. The presentation outlined the differences in the current IEEE and future IEEE testing methods relating to time and percent of rated voltage. He then showed the raw data for layer and disk windings. The layer windings had < 25pC for all reported measurements. The disk windings had (3) ‘fliers’ that were above 100pC and the group discussed the origin of such a PD measurement. It was the general consensus that the PD was external to the windings, but this could not be verified since the waveforms were not supplied to Rick Marek for analysis. A brief discussion followed on the appropriate PD level for Open Wound transformers. Mark Gromlovits made a motion of 50pC for all Open Wound with a second from Carl Bush. The motion passed with 9 for and 2 against.

No Load Loss Correction In San Diego a motion carried that all no load losses should be corrected to 20°C. After that meeting Casey Ballard questioned how the losses should be corrected. He supplied the correlating calculation from C57.12.90 Section 8.4 for discussion. No one present could confirm how the WG for C57.12.90 had determined the equation for loss correction and no actions were assigned to locate the answer. Chuck Johnson questioned the 20°C in lieu of 75°C and Sheldon Kennedy noted that the WG for 12.00 had attempted such a change in the past that was not supported by the end users. No motions were made. The group agreed that the no load loss correction equation belonged in 12.91, but since that document is out for ballot it will not make it into the next revision. Tim Holdway agreed to determine the proper vehicle for including this calculation into a dry type standard.

Altitude Correction The group agreed that a change was needed to allow for the correction of the dielectric insulation levels for altitude. However, the group could not agree on the proper calculation since this correction would be based on a complex insulation system of solid insulation and air. Tim Holdway proposed the use of the Table 1

‘as is’, provide additional wording to explain its use, and add example(s) to the Annex. Tim will circulate his proposal before the spring 2012 meeting.

Miscellaneous Proposed Changes Marcel Fortin agreed to review Tim’s response to his required changes so that all of them could be addressed before the spring 2012 meeting.

Aleksandr Levin had sent to the Chairman a few of his concerns/proposed changes. Tim had sent these out to the members a few days before this meeting. Tim asked that all members please review these proposals and give their comments so we can resolve before the next meeting.

New business No new business was raised due to time constraints

Next meeting: Spring 2012: March 11 – 15 Nashville, Tennessee

With no further business, the meeting was adjourned at 12:17 PM. Motion: Mark Gromlovits Second: Chuck Johnson

10.8.2.2 WG PC57.12.91 - Dry Type Test Code Chair Derek Foster

The working group met at 3:15 pm in the Pacific C Meeting Room of the Renaissance Waterfront Hotel in Boston, Massachusetts with 10 members and 9 guests present.

There were no patent issues regarding this standard.

The minutes of the last meeting, held in San Diego, were approved as written.

The recirculation ballot for this standard, held in early October was successful, with 91% of ballots returned, and 86 affirmative votes of the 92 returned. The document will now be reviewed by RevCom at its December 6th meeting.

Since work on the current revision is now complete, the meeting was spent reviewing several topics which should be considered during the next revision.

These included temperature rise test procedures, short circuit tests, partial discharge tests, dielectric tests for transformers used at high altitudes, and audible sound level measurements.

For the temperature rise test procedures David Vinson and Carl Bush agreed to review this section of the standard.

Marcel Fortin will lead a task force to review short circuit tests.

Marcel also mentioned some topics which are being reviewed by the C57.12.90 task force, and which we may also want to review. These included resistance measurements and impulse voltage wave tail time for low impedance windings.

Regarding partial discharge tests, there was a short discussion on whether to include the contents of C57.124 IEEE Recommended Practice for the Detection of Partial Discharge and the Measurement of Apparent Charge in Dry -Type Transformers, into this document, or whether to include just a reference to C57.124. This will be decided during the revision process.

During the balloting process, a number of comments were received regarding the quality of some of the drawings in the standard, so all drawings and diagrams will be reviewed during the next revision and redrawn where necessary. Casey Ballard agreed to assist with this task.

Casey had raised a question regarding the reference temperature to be used for no load losses and the temperature correction formula to be used. This item is also being considered by the C57.12.01 working group, so we will work with that group on this subject to ensure consistency between the two standards.

The meeting ended at 4:10 pm.

10.8.2.4 WG Dry Type Loading Guide C57.96 Chair Rick Marek

The fourth meeting of the working group was held in the Pacific C of the Renaissance Waterfront Hotel in Boston, MA at 1:47pm with 11 members and 8 guests in attendance. Introductions were made, and the attendance sheet was passed around. With 17 members there was a quorum and the minutes of the last meeting were approved as submitted.

The Chair presented an overview of the 2nd draft and commented on the overall structure of the document. It included some copy/paste information for discussion during the meeting that will not remain in the 3rd draft.

It was brought up that two definitions were missing from Section 3 - Open Wound Dry Type Transformers and Sealed Dry Type Transformer. The Chair asked for three volunteers to submit their proposals and Aleksandr Levin, Chuck Johnson, and John K. John volunteered.

The discussion then moved to Table 1, “Continuous per unit loading capability as a function of ambient temperature”. A question was raised on the ambient temperature level for Table 1 and it was confirmed that it was 30C based on paragraph 4.2 which describes transformer rated output. Mark Gromlovits asked why a 240C insulation system was not included in the document, but declined to make a motion. The Chair advised that inclusion of insulation systems should be addressed in C57.12.01. The attendees of the meeting could not determine what equation was used to develop Table 1 and Sanjib Som volunteered to create the required equation.

A discussion was then held on Table 2, “Influence of altitude on loading”. The attendees of the meeting could not determine what equation(s) was used to fill out Table 2 and Aleksandr Levin and Dhiru Patel volunteered to create the required equation(s).

The life equations were discussed and the chair noted that the variables were based on industry-accepted values. The new document will have similar values, but a manufacturer could use different values based on their internal test data. The chair encouraged the members to review the equations and send him comments.

Chuck Johnson requested that the core temperature estimate in Section 5.3, Page 14, Line 3 be revised to include the text “, other values may be used if test data is available”

The question if the impact of moisture should be included in this guide was raised, but the allotted time for the meeting was exceeded and no discussion occurred.

The Chair agreed to make the discussed changes, remove the duplicate data/tables as referenced above and send to the WG by 1Q12.

Two guests requested membership.

The meeting adjourned at 3:05pm.

10.8.3 Old Business

There was no old business.

10.8.4 New Business

Meeting Minutes / Significant Issues / Comments: Steve opened the meeting; rosters were passed out, introductions were made & by a show of hands of members listed on screen showed we had quorum with 26 of the 47 members in attendance.

The minutes of the spring 2011 meeting of the subcommittee were presented and a motion was made by Gael Kennedy, seconded by Ron Stahara to approve the minutes; the motion carried by unanimous acclamation.

The following are the highlights of the reports that were submitted by the Working Groups and Task Forces. For further, detail please consult the individual reports.

C57.12.36 –Distribution Substation Transformers Jerry Murphy opened the meeting at 8:03 AM on Monday October 31, 2011, in the Pacific AB Room of the Renaissance Waterfront Hotel, Boston, Massachusetts; introductions were made, and the attendance rosters were circulated. Quorum was reached with 17 of the 27 members present. The minutes of the S pring 2011 meeting in San Diego were presented and approved unanimously. Jerry informed that the PAR was submitted to Nescom, and that it will be reviewed for approval at the Nescom meeting in December 2011, and that even though the PAR had not been approved yet, the working could start on th is meeting working on the revi ew of the document with the comment s that were left pending for future consid eration when the standard was approved in 2007. The document with the com ments was then reviewed. Gary Hoffman made a moti on to reject the first comment b ecause it was related with railway transformers, with the consideration that traction t ransformers had a separate committee. The motion was seconded by Steve Schroeder, and it was approved with no one in opposition. Some of the comments on the table seemed to h ave been addressed in th e current standard. Steve Schroeder made a m otion to disregard a comment about Distribution and Class I Power Transformers. Ron Stahara seconded the motion, and it was approved by the majority of the members with 11 in favor and 1 negative. Another comment that was rejected was related with the term Po wer instead of kil ovolt-ampere ratings. After some discussi on, Gary Hoffman made th e motion to r eject this comment, since it was not technically correct and kilovolt-ampere ratings was the standard term used on all other transformer standards. Lee Mathews seconded the motion and it was approved unanimously. Jerry said that he would send by email a draft 1 versio n of the ne w standard that will be under revision, with a password protection given to all the participants of the W G. Gary Hoffman asked to send also the file with comments along the draft. Jerry accepted, and asked the group to revi ew the documents, and send any comments, so that the y can be reviewed for the next meeting in Nashville, and that the PAR was expected to be approved by then. The meeting was adjourned at 9:00 AM.

Distribution Transformer Subcommittee Report C57.12.20 – Overhead Distribution Transformers

The membership re quirements of the W G were reviewed. Attendance at 3 of the last 5 meetings or last 2 consecutive meetings is required for membership. Since the Spring 2011 meeting, 3 members have been removed and 1 new member added. Membership stands at 30. Attendance of the membership was taken and 21 members were present and a quorum was established. The minutes of the Spring 2011 San Diego meeting were approved as submitted. The Chair reported that the recently balloted revision of the C57.12.20 was approved and has been published by the IEEE. The WG discussed whether natural ester fluids should be included in the scope of fut ure revisions. Pre ssure relief valves were mentioned as one item that ne eds to be r eviewed prior to any such change. A motion was made to change “mineral-oil immersed” to “l iquid-immersed” which was seconded and approved with no opposition. A motion was made to accept the title, sc ope and purpose as modified during the meeting which was seconded and approved with no opposition. Following discussion on the temperature ratings of gasket concerns, Chuck Simmons agreed to email the results of the gasket survey completed 1-2 years ago such that the WG can discuss at a future time. Discussion was held on including 600 Volt secondary ratings in the C57.12.20 standard. Gael Kennedy agreed to go through the current revision and determine what changes will be required with the addition. Discussion was held on including 240/120 Volt secondary ratings in the C57.12.20 standard. It was agreed that discussion on including cautionary statements regarding high rates of pressure rise will be deferred until after the TF on Tank Pressure Coordination arrives at a consensus. Meeting was adjourned at 10:06AM.

C57.12.38 – Single Phase Padmount Transformers The meeting was called to order by Mike Faulkenberry. A roll call was conducted to determine if a quorum was present. Twenty-two of thirty-two working group members were present at the time of the roll call. Therefore, a quorum was present. The minutes from the April, 2011, meeting in San Diego were presented and approved. Ali Ghafourian gave the status of the PAR. It is good through 2014. A review of Draft 1.3 which contained changes agreed to in the San Diego meeting was conducted and included the following: It was noted that the scope of the document stated that the standard pertained to

“liquid-filled” transformers as opposed to “mineral oil-filled” transformers. A discussion took place on whether or not the standard should address transformers containing natural ester fluids. A motion was made by Jerry Murphy to leave the document as “liquid-filled” and to include natural ester fluids in the standard. The motion was seconded by Steve Shull and was passed on a vote of the working group members. The manufacturers were asked to provide any changes that need to be made to the standard to account for natural ester fluid use.

The reference to IEEE Standard 386 in the Normative References had been revised to show the year of publication, 2006. Mike Faulkenberry took as an action item to ensure that the apparent reprint dated 2009 should not be the appropriate date.

Figure 4 was modified to address the fact that 250 kVA transformers and voltages of 120 volts and 480 volts are now included in the standard, and it has an effect on the stud size needed. Comments indicated that the table as included needed to be made a little easier to understand. Mike Faulkenberry will work on revising the table for the next meeting.

In Figure 5, 277/480Y was added as one of the new voltages covered by the standard. A question was raised about whether or not figures should be included to show dimensional requirements for the various new bushing arrangements in Figure 5. It was agreed that vertical elevation of the lower bushing, vertical separation to the second bushing level, and possibly horizontal separation dimensions needed to be shown. Rather than figures for all the possible bushing arrangements, it was

Page 2 of 7

Distribution Transformer Subcommittee Report suggested that maybe one drawing with notes to cover other arrangements might be acceptable. Mike Faulkenberry will work on a drawing to address this issue for the next meeting.

Mike Faulkenberry asked the working group members to continue to review Draft 1.3 for any other changes or additions that need to be made. Justin Pezzin gave a presentation on what had been found by the study group formed at the last meeting to study low voltage bushing cantilever loading. They found that some bushing manufacturers provided loading ratings, although they differed, while others did not specify an allowable loading. After some discussion, it was apparent that there are a number of variables that determine what the cantilever load rating will be. It was decided that in lieu of specifying a minimum loading capability in the standard, it may be a better approach to specify how to determine what the loading rating is so that it is done consistently. Carlos Gaytan stated that there was an IEC standard that addressed how to determine this load rating. He will provide the document number, and the working group will review this standard as a reference for specifying the proper method to determine the cantilever load rating for low voltage bushings. The meeting was adjourned at 12:03 p.m.

C57.12.34 – Three Phase Padmount Transformers Ron Stahara called the meeting to order. To establish a quorum, the member list was displayed on the screen and those who saw their names were asked to hold up their hand. From this count of hands, a quorum was declared. Ron asked that everyone introduce themselves by giving their name, company and location. Also, an attendance roster was circulated. A motion was made by Gael Kennedy and seconded by Chuck Simmons to accept the minutes of the past meeting. It was approved by acclamation with no corrections. Jerry Murphy reported for his task force c oncerning the dime nsions of the follo wing manufacturer’s 600A pr oducts: Elastimold, Hubbell Power, Cooper Power System and Richards Manufacturing. He presented the following table while referencing the dimesion shown in Figure 18 of IEEE 386.

From this table it was determined that the depths for 600A terminations were 18” for 15 & 25 kV and 24” for 35kV. Figures 9 and 12 of th e current standard were reviewed. After a lot o f discussion it was determined that the current table listing of the 21.1 and 21.1/36.6 kV column was created for the use of large 200 A interfaces. A consensus was reached for Steve Shull to rework these figures. These were to be resubmitted to the working group prior to the sp ring meeting with columns for 200 and 600 A interfaces as related to kVA sizes and voltages. Likewise he would rework the rema inder of the pertin ent drawings to insure that they reflect the n ew clearances as suggested from the discussion and deliver them as well. Under new business, a d iscussion ensued concerning the placement of the cabinet depth dimension. D wight Parkinson asked for a clarification as the dimension that had been shown in previous editions of the standard which was from the front of the face plate to the outside of the cabinet had been changed in the current edition to that of being from the faceplate to the cabinet flange. Dwight felt that traditionally this had been interpreted to be

Page 3 of 7

Distribution Transformer Subcommittee Report the cabinet clear dimension from the facepl ate to the doo r. Gerry Paiva agreed with this position. Carlos Gaytan and Ali Ghafourian disagreed and believed that this was showing the cable opening for the compartment. After some discussion, it was decided that a side view should be added to this drawing similar to that shown in C57.12.38 to differentiate this dimension and in that way both items could be addressed. A motion was made to this effect by Jerry Murphy and seconded by Ali Ghafourian. It passe d by acclamation. Steve stated that he would work this into t he drawings and at the same time change the table to include the 200 and 600 A dimensions. This concluded the meeting.

C57.12.28 – Enclosure Integrity Introductions of members and guests A quorum of the Working Group's members was present (23 out of 33). The minutes of the April 12, 2011 working group meetings were approved. A review of the C57.12.28 standard was then started. Several sections of the st andard (highlighted in yellow) which were revised after the San Diego Working Group meeting were presented to the Working Group (WG). None of th ese changes required any additional modifications. A concern was expressed by one of the members related to the security of the locking nut in a case where the penta-head bolt was not included in the closing of a device in the field. A wire could be inserted past the padlock and through the nut allowing contact with high voltage components on the fr ontplate. T he following statement was prepared during the meeting: In the ev ent that the bolt is mis sing the design shall be such that the ca binet remains inaccessible through the bolt hole (such as a bl ind hole). The working group than discussed several alternative statements a nd potential test methods. This issue was not resolved during the meeting and the following WG members were requested to develop a statement: Callsen, Ghafourian, Klaponski, Murphy and Rave. The working group was asked to review a test requirement for the doors to latch when the unit is closed and a lift and place test be added to the standard. The person requesting this change was contacted by the WG chairpersons. As a result of this discussion the following statement was added to section 4.3.6: All door's latch points must engage when the door is closed. Two additions were suggested, as designed without adjustment and when the door(s) are closed. A final statement will be prepared and presented to the WG at the next meeting. A potential problem was identified with the ability of Munsell to prov ide a consistent pad mount green color standard. After researching the Munsell Color System, it was determined that the system is still soun d and a reliable company is managing the system. At the last WG meeting several users and manufacturing companies submitted sets of paint test panels coated with their pad mount green coatings. The gloss and color readings were presented to the WG and discussed. All color systems provide both high gloss and semi gloss standards of the same color. Therefore, the Munsell designations for both high gloss and semi gloss color chips will be included in the standard. Bibliography C18 referencing a source to obtain Munsell color stan dards needs to be updated and C57.12.30 added. The meeting came to a conclusion at 9:13 AM.

C57.12.29 – Enclosure Integrity All of the encl osure integrity tests and requi rements included in the C 57.12.29 Standard were covered during the review of the C57.12.28 standard. These two standards are very closely related and share many of the same features. A statement to address the problems associated with the galling of stainless steel hardware was added to the stan dard. The statement utilized was the same one included in the pole mounted enclosure integrity coastal standard C57.12.30. The Munsell color standard designations for both the high gloss and semi gloss will also be included in this standard. There is only one source for outdoor coastal testing since the closure of the LaQue test site in North Carolina. The membership was again requested to research and identify a second source. Bibliography C18 referencing a source to obtain Munsell color stan dards needs to be updated and C57.12.30 added.

Distribution Transformer Subcommittee Report The meeting came to a conclusion at 9:13 AM.

C57.12.35 – Distribution Transformer Bar Coding The WG met on Tuesday, November 1, 2011 at 9:30am in the C aspian Room of the Renaissance Waterfront Hotel in Boston. An agenda was presented and introductions were made. The Meeting Minutes from t he previous meeting in San Diego, CA were reviewed. The minutes could not be approved as a quorum was not present. The wording on a pro posed addition to C lause 4.1.6 co ncerning types of scanners was reviewed. The consensus was that the wording is acceptable. There was discussion as to the proper method to i nsert the i nformation. The chair will check th e current IEEE St yle Manual to d etermine if wording should be added as a note in th e clause or ad ded as a footnote A suggestion was made by Steve Shull to increase the minimum height requirement of the bar code on the temporary bar code label from 0.24" to 0.50". It was agreed that this would be an improvement in the readability of the bar code. Manufacturers present at this meeting were asked to review their labels and bar code printers to determine if t his change would present a problem. The Chair will contact other manufactures not present at this meeting to get their input on this change. A draft with the proposed revisions will be created for review at the next meeting.

C57.12.37 – Electronic Test Data Reporting The meeting w as called to order at 1:4 5pm in the Pacifi c AB Room at the Rena issance Hotel, Boston, MA. Introductions were done. The rosters were passed and role was taken to verify a quorum of the members. A quorum was met. Minutes from the meeting on 10/27/09 in Lombard, IL., the meeting on 3/10/2 010 in Houston, TX., and th e meeting on 4/12/2011 in S an Diego, CA were reviewed and approved. Under old b usiness, the working group reviewed the prev iously proposed changes to th e standard which were related to the ad ditions necessary by the Department of En ergy Efficiency Rules. There was no other old business. Under new business, John Crotty informed the working group that prior to Nov 2011, the WG had been working on a PAR amendment, but the standard reached the end of its five year cycle and thus a ne w PAR was necessary. A ne w PAR request has been submitted to Nescom. John Crotty will review the roster again and reduce the mem bers to those actively participating in the working group. Next meeting the working group will begin a review of the whole standard.

TF Tank Pressure Coordination Carlos opened the meetin g at 3:15 PM on Monday October 31, 2 011, in the Pac ific AB Room of the Renaissance Waterfront Hotel, Boston, Massachusetts ; introductions were made, and the attendance rosters were circulated. Quorum was reached with 18 of the 32 members present.

Minutes from the Spring 2011 meeting in San Diego were approved. Ron Stahara made the motion, and Paul Chisholm seconded it.

Carlos presented a summary of the Spring 2011 meeting, where a motion was approved to create a Title, Scope and Purpose to create a PAR for the TF to move into a working group.

The following was the discussion around the Title, Scope, and Purpose:

We should make a note to insure the standard doesn’t cover external impacts, such as falling ice hitting windfarm transformers.

There was a concern that the purpose as written was too broad and could open up the need for new testing to be completed in the area of dynamic pressure rise and tank withstand. Steve Shull and Carlos Gaytan mentioned that although the purpose is broad, the intention is to collect and standardize the information that is already in the various standards, and that the WG can still decide to further revise the scope at a later time.

Page 5 of 7

Distribution Transformer Subcommittee Report Steve Shull discussed the need for the group to make a decision on whether or not to

move forward as this was the last meeting for the TF and if no decision to form a WG was made today then the TF would be disbanded.

Carlos mentioned that fusing may need to be considered when attempting to describe all possible methods for tank rupture protection as a result of dynamic pressure rise. Gerry Paiva had a strong opinion against discussing fusing as fuses fall under the accessories which these do not cover, and introducing them into the standard would open a discussion into which the transformers committee had previously decided not to engage. Gerry further suggested that this WG “not go down that road”.

A comment was made to ensure that when this WG is considering natural ester fluids we should get representatives from the fluid manufacturers to describe the special requirements for each of the respective natural ester fluids.

Steve Shull made a motion to move forward with application for a PAR with the title, scope and purpose as presented by Carlos. This motion was seconded by Ali Ghafourian. The floor was opened for further discussion but none was given. The motion was voted and approved with no opposition.

Carlos concluded the meeting by reviewing the actions made by the working group which was to apply for a PAR with the information he had presented. If this PAR is approved, Carlos Gaytan would prepare a first draft of the document to be submitted to the working group at the Spring 2012 meeting in Nashville.

The meeting was adjourned at 4:07 PM.

TF – Transformer Efficiency and Loss Evaluation (DOE)

Mr. Hopkinson reported that Brian Coffey from Navigant was unable to attend the meeting. Navigant Co nsulting is a contractor working for DOE on the distribution transformer efficiency rulemaking.

1. Mr. Hopkinson reviewed slides from his p resentation titled “Di stribution Transformer Energy Efficiency Task Force.” The presentation is posted on the IEEE Transformer Committee Website under the Distribution Transformers Subcommittee as "Fall 2011 Agenda & Presentation."

a. Brief overview of the Negotiated Settlement in process for New Final Rules

Richard Parker was appointed by DOE as facilitator for this group.

There are t wo negotiating teams; one for Lo w Voltage Distribution Transformers, and one for Medium Voltage Distribution Transformers /Liquid-Filled

Timing is short for the se teams b ecause the ta rget for their f inal Agreement is the end of 2011

The Agreement must have 100% consensus between all parties.

b. Conservation advocates want higher efficiency, manufacturers and u sers want economically justified efficiencies while using widely available materials.

c. Major push is to verify e conomic models, BIL sensitivity, and impact s on suppliers, manufacturers, and users.

d. If Agreement is not rea ched, the d ecision reverts back to traditional rulemaking.

e. Meetings scheduled November 8-9, and November 30-December 2.

2. Studies by Phil Hopkinson, Carlos Gaytan, and Wes Patterson were presented.

a. Mr. Hopkinson reviewed portions of his analysis that was submitted to DOE.

There are inaccu racies in the OPS model use d by DOE, It underestimates the amount of material used for these designs

Page 6 of 7

Distribution Transformer Subcommittee Report

Page 7 of 7

There does not appea r to be eco nomic justification for h igher efficiencies than the current mandatory levels.

b. Carlos Gaytan reviewed his report submitted to DOE whi ch highlighted steepness of the cost curve of amorphous steel compared to M3 steel.

c. Wes Patterson reviewed his reports submitted to DOE:

One report highlighted efficiency rules from other countries around the world.

One report showed the weight of the transformer as efficiency is increased. 30% reduction in losses resulted in 15% increase in weight. If restricted to M3 steel, a 30% reduct ion in losses will result in 85% increase in weight. The conclusion of this report shows DOE analysis underestimates the weight of more efficient transformers.

3. DOE rulemaking does not cover rebuil t transformers. There is a price point where users will opt to rebuild transform ers rather than purchase a new, more efficient transformer.

4. There was not any new business.

The next meeting is planned for the Spring 2012 in Nashville.

The meeting adjourned at 4:32 PM.

Old Business:

Steve asked if there was any old business to review and none was presented.

New Business:

Steve briefly discussed the changes to the overall meeting agenda that will occur at the next TC meeting in Nashville, TN in an effort to have better participation in the overall committee & WGs. Of interest to the Distribution Transformers SC, the EL&P (user only) meeting will move to Sunday at 3pm facilitated by Jerry Murphy.

Jerry Corkran thanked Phil Hopkinson for the DOE TF and their efforts further stressing that members get involved by contacting their legislators & regulators stressing the need to not burden the public with extreme efficiency standards that will have unintended consequences to the end consumers.

Phil Hopkinson responded in agreement. Chuck Simmons (another DOE panel advisor) indicated he was hopeful the DOE will accept the recommendations the advisory panel has submitted considering the real desire is to reduce cost to consumers and some of the proposed regulations would not meet that goal and would add to consumer cost.

Steve Schroeder made a comment concerning NEMA TR-1 not keeping pace with the industry.

Steve adjourned the meeting with unanimous consent at 10:38am.

10.10 Dielectric Tests Subcommittee – Loren Wagenaar, Chair; Thang Hochanh, Vice-Chair; Joe Melanson, Acting Secretary

The Dielectric Tests Subcommittee (DISC) met on Wednesday, November 3 at 11:00 am with 175 persons in attendance. There were 78 of 128 members, and 97 guests present. Eleven returning guests requested membership and will have their participation status reviewed prior to acceptance 10.10.1 Chair’s Remarks 1. The Chair first announced that Secretary Dennis Marlow could not attend this meeting and

that Joe Melanson agreed to fill in. 2. The Chair briefly reviewed highlights of the Administrative Subcommittee meeting held on

Ed Smith will move to the Awards chair, present vice chair Bill Chiu will move to chair, present secretary Don Platts will move to vice chair, and Steve Antosz will become secretary.

5. The patent policy remains the same, but the method for achieving compliance has changed.

Rather than the chairs having to ask for patents before each meeting session, the new method is to handle this on a one time basis at the time of meeting registration.

10.10.2 Quorum and Approval of Minutes 1. A show of hands of committee members present showed that a quorum of members were in

attendance at the start of the meeting. 2. The minutes of the Spring 2011 meeting in San Diego were approved without correction.

10.10.3 Working Group Reports 10.10.3.1 Working Group on External Dielectric Clearances, Eric Davis, Chair; Dennis

Marlow, Secretary The basic parameters that affect the BIL and SIL breakdown voltages were reviewed. These parameters include the impulse shape, impulse polarity, gap configuration and atmospheric conditions. This background information will be posted in a secure portion of the DISC’s web site. We are currently working with IEEE to get the necessary permissions to post the papers and standards. The WG also reviewed and refined several survey questions regarding BIL. The survey along with the background information discussed above will be sent to the members of the DISC. 10.10.3.2 Working Group for Revision of the Impulse Test Guides C57.98, Art Molden,

Chair; Joe Melanson, Co-Chair The meeting started at 9:30 AM on Tuesday November 1, 2011. Introductions were made of the attendees. Chair Art Molden was unable to attend. There being four members present a quorum was declared, and the minutes of the spring meeting in San Diego were approved. The Guide has been completed, balloted and forwarded to RevCom. The Chair acknowledged the special contributions from Art Molden and Bertrand Poulin to the Guide during the revisions. The attendees also acknowledged their efforts to make the Guide a more informative and in depth document. The meeting was then adjourned and turned over to John Crotty, the chair of the next working group charged with revision of the Recommended Practice for Routine Impulse Test of Distribution Transformers. 10.10.3.3 Working Group for Revision of C57.138, Recommended Practice for Routine

Impulse Test of Distribution Transformers; John Crotty, Chair The group met briefly at 9:45 AM on Tuesday, November 1, 2011 in their kick off meeting. The chair reported that the PAR had already been approved and circulated a signup sheet for those interested in working on the revision. He will send out comments from the reaffirmation ballot sent out in 2005. Work on the revised document will begin in Nashville.

10.10.3.4 Working Group on Revision of Low Frequency Tests; Bertrand Poulin, Chair;

Bill Griesacker, Secretary

There were 86 attendees, 20 members and 68 guests; 17 guests requested membership. There were well more than 50 % of the working group members present at the meeting, therefore there was a quorum present at the meeting. The minutes from the spring 2011 meeting in San Diego, CA were brought to the table; the minutes were approved.

10.10.3.4.1 TF on PD in PTs, CTs and Bushings, Thang Hochang, Chair

Thang presented the minutes for the TF. A proposed bushing test circuit was sent out for comment. The document has been drafted and is ready to be sent for review and comments. A PAR will be initiated for this work. Full minutes are given in the Annex. 10.10.3.4.2 TF on Electrical Partial Discharge Measurements Guide, C57.113, Eberhard

Lemke Chair The TF did not meet as the document is being published. Note: A check after the meeting reveals that the guide was published on August 20, 2010. WG Discussion Old Business: The topic of requiring induced testing on 69 kV transformers was discussed. Two e-mails were sent out, 119 responses were received for a 33 % return rate. Reviewed negative votes and the accompanying comments which will be used to guide a draft proposal(s) for new requirements in the standards (i.e. C57.12.00, C57.12.90). Suggestions were given to consider other criteria, such as MVA along with kV, to determine if this test should be required. It was voted 12 to 0 to issue a new survey proposing that the induced test is required for 69 kV and an MVA level. Values such as greater than 10, 12 and 15 MVA were proposed.

New business: It was discussed if it should be required to perform the induced test on transformers with reactive type LTCs on a bridging position. One philosophy is to adjust the LTC so that there is the closest match on primary and secondary winding terminals to the calculated test voltage. One possibility would be to require a bridging tap position (or a position that the PA has induced voltage during test) with a secondary requirement to select the tap position which provides the closest terminal voltage. This may impose limiting requirements on the generator that may not be able to deliver the power required by the test at higher frequencies. A survey proposal will be prepared to get a general consensus if this topic should be addressed.

The meeting adjourned at 3:00 p.m. Annex. Minutes of TF on Partial Discharge in Bushings and PTs/CTs, Chair Thang Hochanh; Arturo Del Rio, Secretary The task force met on Monday October 31st, 2011, at 3:15pm with 50 attendees. Of those, 12 members and 38 guests with 3 guests requesting and granted membership.

• The meeting was opened with a request for patent disclosures and introductions. • The minutes for the S11 San Diego meeting were presented. Volunteers were reminded

of the previously offered contributions to the draft; W. Hauschild offered to have the section of shielding ready for next meeting after clarifying details with the Chair.

• The TF Chair presented a draft version of the preferred connection diagrams for carrying out PD tests in laboratory settings for transformer bushings and instrument transformers both in balanced method and open-end method. Also, alternate connection set ups were presented and discussed. These diagrams are intended to be part of the guide.

The diagrams will be e-mailed to the members of the task force for review and comments.

• The TF Chair presented a table summarizing the different aspects to be considered prior and during the PD test including physical set up, oil tank size, use and size of corona rings, use and size of static shields in the oil side of a bushing, influence of ground planes during the test, cleaning and preparation of equipment prior to the test, set up and test connections and instrumentation. This table will be e-mailed to the members of the task force for review and comments.

• The final item in the agenda was a presentation by Barrett Wimberly on routine partial discharge for CTs 72.5 kV and 800 kV.

• TF chair requested comments and feedback from the members regarding the material and schematics presented.

• Meeting was adjourned at 4:30 pm. Minutes by Arturo Del Rio. 10.10.3.4 Working Group on Revision of Impulse Tests – Pierre Riffon, Chair;

Peter Heinzig, Vice-Chair The WG did not meet because of a lack of a quorum. 10.10.4 Liaison Reports 10.10.4.1 High Voltage Test Techniques (HVTT), IEEE Standard 4 - Arthur Molden There was no report due to the fact that Art was not present at the meeting 10.10.4.2 PCS TF on Dielectric Frequency Response Testing – George Frimpong Four groups were formed during the San Diego to handle various aspects of the project. These groups presented progress reports at this meeting.

• Subtask 1 – Literature Survey George Frimpong presented a list of abstracts from papers related to the modeling and estimation of moisture in transformers using DFR and other dielectric response methods. In all a total of 25 key papers have been identified, some of which deal with verification of DFR for moisture estimation.

o Mary Foster from Omicron suggested the inclusion of the CIGRE Working Group D1.01 (TF 14), Report 414 on Dielectric Response Diagnoses for Transformer Windings, 2010.

• Subtask 2 – DFR Method Description Peter Werelius presented the material that has been put together to explain the basics of the DFR method.

• Subtask 3 – Verification/Validation Tom Prevost and Diego Robalino presented case studies on transformers for which DFR measurements and other moisture determining measurements (dew point and Karl Fischer on paper samples) were performed. Tom requested anyone who has cases of DFR moisture measurements in conjunction with other moisture measurements to send these to him and Diego for review and inclusion in the task force report. For

completeness we ask also for cases where DFR did not work in estimating moisture in the solid insulation. Tom presented a list of information to include with the cases.

o The chair clarified that the task force will focus only on cases related to moisture determination in power transformer solid insulation.

o A table to address DFR measurement parameters and to quantify their diagnostic value was presented. The table will be reviewed by the subgroup before the next meeting.

• Next Step for Subtask 3 o Complete draft of this section by end of January 2012 and distribute among

subtask members for comment • Subtask 4 - Mario Locarno presented a review of existing IEEE, CIGRE and IEC

documents that have a relation to moisture estimation in transformer solid insulation. In all about 20 documents were found that mention moisture estimation or DFR.

10.10.5 Old Business The WG on the Revision of Low Frequency Tests presented a tutorial on Monday afternoon. The presentation was well received. Phil Hopkinson reported on the status of comment resolution on the dielectric tables in C57.12.00. One of the comments was raised by Fred Elliott relative to 500 kV, in that the latest table has test voltage requirements of 520 kV and 460 kV for the enhanced and one hour induced test, respectively, whereas the previous levels were 550 kV and 475 kV, respectively. There are a few additional comments generated during the ballot. Phil commented that WG may be re-activated and asked for volunteers. Dennis Marlow raised the issue of the order of switching and lightning impulse tests at the last meeting. This issue was raised at the meeting, but there was no discussion, perhaps because Dennis was not in attendance. 10.10.6 New Business Front of Wave Test. Joe Melanson proposed that Annex A in C57.12.00 be changed to remove the Rate of Rise column in the table, to add tolerances to time of flashover, and to remove the statement in the title block stating that this test is no longer specified but is documented for historical purposes. This proposal was not surveyed at the meeting, but an amendment to the proposal was to survey all members of the DISC on this issue. Both the amendment and the proposal to survey all members passed. Joe and the Chair will put out a survey on this issue. Polarization Index Tests. The chair received an inquiry from an engineer from a testing organization questioning why requirements for this test were not stated in C57.12.90. This test is a field diagnostic test, and test requirements are stated in the revision of C57.152, Guide for Diagnostic Field Testing in Fluid Filled Transformers, Regulators and Reactors. General consensus of the DISC was that users who wanted this test as a baseline should place a requirement for such in their specifications, but requirements for it should not appear in C57.12.90 at this time. Revision of C57.127-2007, Guide for the Detection of Acoustic Emissions from Partial Discharges in Oil-Immersed Power Transformers. Information at the meeting was that this guide

would have to be revised by the end of 2012. However, discussion at the Standards SC indicates that under the new rules, it does not have to be revised until the end of 2018. Hence, if this is the case, there is ample time to revise this document in a timely fashion. The .chair will confirm the required date and will attempt to determine the need for revision. Tutorial on IEEE 4 Revision. In view of the several changes made in the latest revision of IEEE 4, Art Molden has suggested that a tutorial be given to the TC. A major change deals with the “k-factor,” which is a correction factor for the overshoot on the front of lightning impulse waves. The proposal was discussed, and one thought was that it should be presented only to the DISC. However, the counter argument was that while this is a complex subject directed specially at impulse testing, it is of general concern to both users and manufacturers. A vote was taken and the general consensus was that it should be a TC tutorial. The chair will contact the tutorial coordinator to determine the next available date for a tutorial and also contact Art to advise him of the DISC approval of the proposal. Class I/Class II Classification for Transformers. This subject was raised in the Administrative SC and has major impact on the DISC, which has the majority of special test requirements for Class II transformers. Bill Chiu presented power point slides discussing the diminishing need for these classifications. The chair pointed out that this topic had been raised several times before, that a 2010 DISC survey indicated that about 70 % approval for impulse testing all power transformers, and that this is not a large enough approval rate for a Standards Association ballot. This topic was discussed further at the Standards SC, and the PCS has agreed to follow the lead of the DISC. The DISC chair has agreed to take the lead on this assignment, and Bill Chiu’s presentation will be posted on the Standards SC website. 10.10.7 Meeting adjourned 12.15 PM. Minutes respectfully submitted by Joe Melanson and

10.11 HVDC CONVERTER TRANSFORMERS & SMOOTHING REACTORS S.C.

MINUTES OF THE MEETING OF THE HVDC CONVERTER TRANSFORMERS & SMOOTHING REACTORS S.C. IN BOSTON, MASSACHUSETTS, OCT 31, 2011

On October 31, 2011, the HVDC Converter Trans formers and Smoothing Reactors S.C. met at 1:45 p.m., in the Pacific C M eeting Room of the Renaissance Waterfront Hotel, in Boston, Massachusetts. There were 9 members and 17 gues ts present. The total membership of the SC is 26, but currently includes 8 corresponding members. (Note that the chairman will review the current membership and especially the st atus of members who have not recently participated in the business of the SC; especia lly those who are corresponding members.) Therefore there was a quorum. The following are the highlights of the meeting: 1. Introductions were made and the attendance list circulated. 2. Although a quorum was not initially achieved a few late arrivals allowed a quorum to be

reached. As there were no dissensions t he minutes of the S an Diego, California meeting are considered to be approved.

Note: The minutes of the Boston MA m eeting will not be approved until the SC

meeting in Nashville. 3. IEEE patent policy was reviewed and no issues were raised. 4. The Chairman provided a synopsis of the Administrative SC meeting. 5. The chairman reviewed the status of his se arch for individuals who would be willing to

volunteer to take over management resp onsibility for the HVDC SC. After man y requests and discussions with members only one individual has agreed to as sume the position of chairman; Mike Shar p. Les Rec ksiedler has agreed to be vice-chairman. (Note that approval of these positions is made by the exec utive of the Administrativ e SC) (Also note that fo llowing the HVDC S C meeting two individuals volunteered to be secretary and a long time member and si gnificant contributor, Ulf Radbrandt, was accepted.) (Note that prior to the Thursday General Meeting all three individuals were approved by the AdCom executive.) (The outgoing chairman, Richar d Dudley, subsequently volunteered to provide all necessary ongoing support to the new team in order to provide a smooth transition.)

6. At the San Diego meeting it was agreed that since HVDC projects are now in service at

666kV and 800 kV the focus of revision work on IEEE C57.129 and IEEE 1277 should be to extend the applicability to 1100 kV. T o help answer the question as t o whether standard insulation levels should be introduced for the highest dc voltage levels or if insulation levels should be s pecified on a pr oject basis Ulf Radbrandt volunteered to make a presentation at the Boston SC meeting on systems aspects of insulation levels. The focus of the Boston meeting was t he presentation by Ulf Radbrandt. The

presentation will be posted on the Trx Com web site with these meeting minutes. Some of the highlights of discussions re the presentation are as follows.

(i) Protective margins are mainly required to compensate for the physical location of surge arresters, i.e. distance effects.

(ii) Insulation levels are very pr oject specific and are system design related.

(iii) Utilities may favor standard insulation levels as it may result in some equipment standardization. However it could res ult in higher insulation levels. There could be cost implications; specific equipment, such as converter transformers (internal insulation costs, including oil volume, and external insulation, including bushing cost and dielectric clearances), but al so overall system costs. Higher insulation levels may also genera lly impact exter nal dielectric clearances.

(iv) Higher insulation levels may have an impact on test lab capabilities. (v) HVDC converter stations are essentially “tailor made” and insulation

levels for components are part of the system design process. (vi) “IEC 60076-5 Insulation co-ordinati on – Part 5: Procedures for high

voltage direct current (HVDC) c onverter stations” is only spec ific re insulation levels for the ac side and the remainder of the converter station is less standardized.

(vii) The insulation levels for the ac side of the converter transformer can be lower than the insulation levels for the other equipment on the same ac s ystem. The reason is t hat surge arresters are normally located very close to the converte r transformer and the protection levels of those arres ters are very low (in order to not overstress other arresters in the ac network and to limit the stresses to the converter valves).

Based on the presentation and di scussions, consensus was reached that insulation levels should not be standardized and that an annex should be added to IEEE C57.129 and IEEE 1277 explaining the rationale. Ulf Radbrandt agreed to produce the first draft of an annex on insulation co-ordination and non-standard insulation levels.

7. Presentations on future work and revisi ons were disc ussed. It was agreed that the

focus should be on additions to existing document versus new documents. The Chairman requested that S C members prepare presentation ma terial on future work for the Nashville meeting as a basis for discussi on and to provide more direction for future revision work on IEEE C57.129 and IEEE 1277 and/or guides on design review and life assessment.
