A component is any individual discrete piece of equipment included in a Protection System, including but not limited to a protective relay or current sensing device. The designation of what constitutes a control circuit component is very dependent upon how an entity performs and tracks the testing of the control circuitry. Some entities test their control circuits on a breaker basis whereas others test their circuitry on a local zone of protection basis.
Definitions: Component
![Page 15: PRC-005-2 Workshop July 29-30 2014 Salt Lake City Utah · 7/29/2014 · PRC-005-2 Workshop July 29-30 2014 Salt Lake City Utah Updated for final posting August 12, 2014 Phil O’Donnell,](https://reader035.vdocuments.net/reader035/viewer/2022063007/5fb9d113bd1d5757651fd6f4/html5/thumbnails/15.jpg)

Thus, entities are allowed the latitude to designate their own definitions of control circuit components. Another example of where the entity has some discretion on determining what constitutes a single component is the voltage and current sensing devices, where the entity may choose either to designate a full three-phase set of such devices or a single device as a single component.

• An ongoing program by which Protection System components are kept in working order and proper operation of malfunctioning components is restored. A maintenance program for a specific component includes one or more of the following activities:
• Verify — Determine that the component is functioning correctly. • Monitor — Observe the routine in-service operation of the component. • Test — Apply signals to a component to observe functional performance or
output behavior, or to diagnose problems. • Inspect — Examine for signs of component failure, reduced performance or
degradation. • Calibrate — Adjust the operating threshold or measurement accuracy of a
measuring element to meet the intended performance requirement.

Overview of PRC-005-X(X) DGR SDT Recommended Changes • DGR SDT scope limited to recommendations on
Standards applicability to DGRs • Changes made in tandem with Project 2007-17.3
(Sudden Pressure Relays) • Changes clarify the applicability of PRC-005-X to DGRs
• The DGR SDT made no substantive changes to the Standard • Section 4.2.5 separated into two sections (4.2.5 and
4.2.6) • Differentiates between typical Bulk Electric System generator
Facilities and BES generators • The applicability to DGR Facilities has been modified and
relocated from 4.2.5 to 4.2.6.

Applicability PRC-005-2/3/X
• 4.2.6 Protection Systems for the following BES generator Facilities for dispersed power producing resources identified through Inclusion I4 of the BES definition:
• 4.2.6.1 Protection Systems for Facilities used in aggregating dispersed BES generation from the point where those resources aggregate to greater than 75 MVA to a common point of connection at 100 kV or above.
• Rationale for 4.2.6: The Facilities listed that are applicable to dispersed power
producing facilities are covered within 4.2.6. The intent is to NOT include the individual generating resources in the Protection System Maintenance Program, and as such the Protection Systems within the individual generating resources would not be within the scope of PRC-005. Only Protection Systems on equipment used in aggregating the dispersed BES generation from the point where those resources aggregate to greater than 75MVA to a common point of connection at 100kV would be included in the Protection System Maintenance Program, including the Protection Systems for those transformers used in aggregating generation.

Applicable Relays The NERC Glossary definition of a Protection System includes relays, dc supply, current and voltage sensing devices, dc control circuitry and associated communications circuits. The relays to which this standard applies are those protective relays that respond to electrical quantities and provide a trip output to trip coils, dc control circuitry or associated communications equipment. This definition extends to IEEE Device No. 86 (lockout relay) and IEEE Device No. 94 (tripping or trip‐free relay), as these devices are tripping relays that respond to the trip signal of the protective relay that processed the signals from the current and voltage‐sensing devices. Relays that respond to non‐electrical inputs or impulses (such as, but not limited to, vibration, pressure, seismic, thermal or gas accumulation) are not included.

• An auxiliary relay, IEEE Device No.# 94, is described in IEEE Standard C37.2‐2008 as: “A device that functions to trip a circuit breaker, contactor, or equipment; to permit immediate tripping by other devices; or to prevent immediate reclosing of a circuit interrupter if it should open automatically, even though its closing circuit is maintained closed.”

• A lock‐out relay, IEEE Device No.# 86, is described in IEEE Standard C37.2 as: “A device that trips and maintains the associated equipment or devices inoperative until it is reset by an operator, either locally or remotely.”
• Software‐latch 86 that replaces an electromechanical 86 does not require routine trip testing
• Any trip circuitry associated with the “soft 86” would still need applicable verification activities performed, but the actual “86” does not have to be “electrically operated” or even toggled

Reactive Resource “3” is connected through a dedicated transformer with a high-side voltage of ≥ 100 kV and is therefore considered to be a BES Element. The dedicated transformer does not meet the inclusion criteria established by Inclusion I1 and is therefore not considered to be a BES Element

“Single Point of Connection of 100 kV or higher” is where the radial system will begin if it meets the criteria of Exclusion E1, including parts a, b, or c. For example, the start of the radial system may be a hard tap of the Transmission line, or could be the tap point within a ring or breaker and a half bus configuration. The connection to the radial system must be from only one point at 100 kV or higher. Any group of contiguous transmission elements that have multiple connections at 100 kV or higher do not qualify for Exclusion E1. Normally open switching devices between radial systems, will not disqualify a radial system from this exclusion.
