1.4 Setup the Equipment The setup of this equipment has been minimized by careful

consideration of the operator during design. The DTS-60xx one-piece construction permits convenient portability. The DTS-60xx test set requires that the unit is operated with the control panel in the horizontal position, to keep oil level over high voltage transformer in the high voltage tank.

1. Select a location for the unit that will allow easy

viewing of the User Interface 2. Be sure that all the controls are off, in their de-

energized state. 3. Remove all components and oil vessels from the test

chamber 4. Install the input line cord into the Input Power

receptacle 5. Connect the line cord to a suitable (120V or 230V,

see Specifications Table) grounded power source. 6. Select the desired Test cell. Fill in with sufficient

insulating liquid for the testing to be performed.

7. Clean the Test Cell and Electrodes thoroughly and adjust the electrodes to conform with the proper ASTM Specification. Be sure the electrodes are securely tightened on the adjustment posts inside the oil vessel.

Use Isolation transformer (1/1) if the electrical installation has neutral earthing.

All the oil vessels designed and made by High Voltage Inc. have interchangeable posts and electrodes. These oil vessels were designed to conform to the ASTM test


15

specifications requiring simple disassembly for cleaning. This design greatly reduces the time and effort required keeping your oil vessels in top operating condition.

The operator of this equipment must use good judgement and follow all safety precautions noted in this guide to ensure the protection of himself and others in close proximity to the test area. Failure to follow the instruction could result in injury or death.


16

1.6 Startup the Equipment 1. Ensure that setup has been completed as noted in

paragraph Setup the equipment (1.4). 2. Turn on Main Power. 3. The equipment initiates a self-test, Figure 1.13. In case of

malfunction, an error message (see paragraph 1.3.4) is displayed and the system will be halted.

generates an (adjustable rate) high voltage ramp until a breakdown happens. The user may repeat the procedure for one insulator-oil filling and that will be considered as a single test. The possible settings are the rate of rise for the voltage and the stirrer control. At the end of the test the system will prompt the user for a printout and the test results will be stored in the History structure (see paragraph xxx).

5 User Defined Tests

This section describes the operations of the User Defined Tests procedure. All system's tests except the Simple Test (Standard and User Defined) are based on the same operational model, which will be analytically presented in the following paragraphs. 1. Test Description 5-2

5.1 Test Description The DTS60A dielectric oil tester supports the execution of user

programmable testing scenarios. The main objective of the programmable test is the control of the high voltage on a time basis. Moreover, the test includes options for controlling the Stirrer and the Breakdown measurements. In this paragraph, a detailed description of the test program structure, as well as the test operations are presented.

5.1.1 Test Structure The Test consists of an Information Session, a Startup Session,

and a Main Session. The Information Session contains general details for the test. These are the following:

a. Program Name (up to 12 characters) b. Electrodes Spacing (mm/in) c. Number of Stages (see Main Session) d. Creation Date/Time

The Startup Session refers to the start-up time. This is the period after the starting of the test (after pressing the ENTER key) until the system enables the output voltage to the oil-sample. The parameters included in the Starup Session define the Wait Time (SWT) after the start of the test and the part of this time (or all this time) the enable or disable of the stirrer. The Startup Session includes the following programmable parameters:

a. Startup Wait Timer (sec) - SWT b. Startup Stirrer Timer (sec) -SST

The Main Session consists of a series of a maximum of 30 Stages. Every stage includes a set of programmable parameters:

a. Voltage Type (kV or kV/sec) Two are the possible voltage types. If a rated increase/ decrease is desired, the type refers to kV/s. If a stable voltage is desired, the type refers to kV.

b. Voltage Value (kV) or Voltage Rate (kV/s) c. Stage Duration (sec) d. Stirrer Timer (sec) - ST

This timer starts counting from the beginning of the current stage and enables the stirrer for the programmed time.

e. After Breakdown Wait Timer (sec) -ABDWT


50

After a breakdown occurs, the system will idle for this programmable duration.

f. After Breakdown Stirrer Timer (sec) -ABDST After a breakdown occurs, the system will enable the stirrer for this programmable duration.

g. After Breakdown Stage (0…29, next, end) - ABDSTG After the above timers the test will proceed to another stage. This programmable parameter indicates the next stage. The value can be any following stage (eg. If current stage is 10 then the value could be 11 to 29), next if it is desired to continue to the next stage, or end if it is desired to stop the test.

h. Store Breakdown Voltage (yes/no) If the user selects the yes option, the detected breakdown voltage will be calculated to the statistics. Otherwise, the detected breakdown voltage will NOT be calculated into the statistics.

In the following paragraph there is a detailed description of the Test

Program Operation, thus the reader will understand the exact meaning of the above parameters.


51

5.1.2 Test Operations Every Test operates according to the programmable parameters of the

above sessions. This paragraph will describe the operations of the system in respect with the programmable parameters.

During Startup the system initializes the Startup Wait Timer - SWT

and the Startup Stirrer Timer - SST. The system introduces an idle operation time according the 1st timer, which is used as a ‘Wait time after filling period’. During this time the system could turn on the stirrer according the 2nd Timer. If the 2nd Timer is zero the stirrer is disabled.

The Test continues the operation according to the parameters described

in the 1st Stage. The Voltage Parameter and the Duration are inputs to the voltage controller, which will control the high voltage output. More specifically, if the voltage value indicates kV then the voltage controller will immediately adjust (according to the maximum system’s rate) the output voltage to the programmed value therefore keeping the voltage stable for the specified Duration Parameter. If the voltage value indicates kV/sec then the voltage controller will adjust the output voltage according to the desired rate for the specified duration. It is noted that the Duration Parameter could take the value “Breakdown” which means no specified duration.

During both situations, if a breakdown is detected the output voltage is

immediately disconnected (turned-off) and the Test Program proceeds with the After Breakdown Wait Timer - ABDWT and the After Breakdown Stirrer Timer - ABDST. During the 1st of these timers the system will be idle, concerning the output voltage. Moreover, the stirrer will be enabled for a duration according to the 2nd timer.

The Test Program will proceed to the stage indicated by the After Breakdown Stage – ABDSTG parameter (0-29). There are the following exceptions: i. Indication of a stage prior to the current stage leads to program

termination ii. Indication of a stage next (30) leads to next stage iii. Indication of a stage end (31) leads to program termination

It is noted that after every breakdown the output voltage will be

initialized, thus the next stage’s start voltage will be zero (0 kV). If a breakdown isn’t detected, the program proceeds to the next stage bypassing


52

the After Breakdown Wait Timer, the After Breakdown Stirrer Timer and the After Breakdown Stage.

The test termination will prompt the user to print a test results receipt

and finally displays a Results screen. The above operations are illustrated in Figure 5-1.

5.4 Script Files for Tests In order to achieve a faster method for updating the equipment’s Tests, an alternative method is supported. The method is based on Script Test Program Files, that the user could develop using an editor on a Personal Computer (PC). The following paragraphs explain the commands and arguments of the specific script files. Furthermore two examples are presented. The Script Test Files downloading to the equipment is described in chapter 8 (Remote Operation).

5.4.1 Script File Commands and Arguments The Script Test Program Files are based on the following command

End of the Test Script File

Two examples follow, in order to clarify the development of script files.


64

5.4.2 Script File Test Examples In order to make clear the above descriptions two examples will be

mentioned. The first one concerns the IEC 156/63 International Standard and the other a more complicated scenario.

a. IEC 156/63 International Standard

The IEC_156/63 Standard is a 6 Stages program. Every stage is independent, which means that it is desired that every stage will have a breakdown. After filling the oil sample it is required to wait for 10 minutes. Every stage voltage will start from zero until breakdown, with a voltage increase rate of 2kV/s. After every breakdown, the test will store the output voltage (breakdown voltage) and then it is desired to wait for 5 minutes with the stirrer enabled for 1 minute. After every breakdown the test will proceed to the next stage. Finally, it is required for the system to print a results report.

The IEC 156/63 Standard should be described in a Script Test File as follows:

Script File 1 – IEC_156/63 Standard prg 0 new IEC-156/95 2.5 0.05 mm type_I_II 00:05:00 00:05:00 06 prg 0 stage 00 002.0 kV/s breakdown 00:10:00 00:02:00 00:02:00 next store prg 0 stage 01 002.0 kV/s breakdown 00:10:00 00:02:00 00:02:00 next store prg 0 stage 02 002.0 kV/s breakdown 00:10:00 00:02:00 00:02:00 next store prg 0 stage 03 002.0 kV/s breakdown 00:10:00 00:02:00 00:02:00 next store prg 0 stage 04 002.0 kV/s breakdown 00:10:00 00:02:00 00:02:00 next store prg 0 stage 05 002.0 kV/s breakdown 00:10:00 00:02:00 00:02:00 end store prg 0 end


65

b. Complicated Example Consider a more complicated example, depicted in Figure 22. The 1st

10min 0 kV duration is the Startup Wait time. After this the program consists of 7 stages:

b. 1st stage : 1kV/s for 10 sec c. 2nd stage : 10kV for 10min d. 3rd stage : 2kV/s for 10 sec e. 4th stage : 30kV for 10 min f. 5th stage : 3kV/s for 10 sec g. 6th stage : 60kV/s for 10 min h. 7th stage : 4kV/s until breakdown In case of breakdown (in anyone stage) the program is desired to

terminate and no after breakdown wait and stirrer timer are needed. The script file for such a program is given in the next page.

It is possible to replicate the whole test, in order to make a more

complex scenario. For example, a 4 replicated test scenario could be a Test with 28 stages. In such a test the user should edit the After Breakdown Stage parameter, in order for the operation to proceed with the first stage of the next replica. It is noted that after a breakdown 10 min idle time will be programmed and all this time the stirrer will be enabled.

92

8.7.4 test download The test download command is used for downloading a user- defined

test. By entering the command the system is ready to receive a Script Test File (see paragraph 4.4.2), which describes a specific test scenario.

In order to simplify the program downloading the user can send a text file through the Terminal Software directly to the system. It is noted that the terminal software should be settled to transmit with a delay of 50 ms in every character, Figure 8-11 (e.g. for TeraTerm).

Figure 8-13 – Set-up the Terminal Software (TeraTerm)

After making the terminal set-up the user must start a transmission of a

script file in Text Mode, Figure 8-12. When the file is transmitted to the equipment it enables echo back, in order to display the received characters.
