Checking Operate And Reset Values; Completing The Test - ABB Relion 650 Series Commissioning Manual

1MRK 505 264-UEN A
Values of the logical signals for TRPTTR are available on the local HMI under Main menu/Tests/
Function status/Current/TRPTTR(49,T>)/X:TRPTTR. The Signal Monitoring in PCM600 shows
the same signals that are available on the local HMI.

Checking operate and reset values

1. Connect symmetrical three-phase currents to the appropriate current terminals of the
IED.
2. Set the Time constant 1 (
3. Set the three-phase injection currents slightly lower than the set operate value of stage
IBase1 , increase the current in phase L1 until stage IBase1 operates and note the operate
value.
4. Decrease the current slowly and note the reset value.
Check in the same way as the operate and reset values of
5. Activate the digital input for cooling input signal to switch over to base current
6. Check for all three phases the operate and reset values for
described above for stage
7. Deactivate the digital input signal for stage
8. Set the time constant for
9. Set the injection current for phase L1 to 1.50 ·
10. Connect a trip output contact to the timer and monitor the output of contacts ALARM1
and ALARM2 to digital inputs in test equipment.
Read the heat content in the thermal protection from the local HMI and wait until the
content is zero.
11. Switch on the injection current and check that ALARM1 and ALARM2 contacts operate at
the set percentage level and that the operate time for tripping is in accordance with the
set Time Constant 1 (
With setting Itr = 101%
content in the memory shall be 0.60 · Time Constant 1 (
12. Check that all trip and alarm contacts operate according to the configuration logic.
13. Switch off the injection current and check from the service menu readings of thermal
status and LOCKOUT that the lockout resets at the set percentage of heat content.
14. Activate the digital input for cooling input signal to switch over to base current
Wait 5 minutes to empty the thermal memory and set Time Constant 2 (
accordance with the setting plan.
15. Test with injection current 1.50 ·
tripping and the lockout reset in the same way as described for stage
16. Finally check that start and trip information is stored in the event menu.

Completing the test

Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/1:TESTMODE. If another function is tested, then set
the parameter
TRPTTR(49,T>)/X:TRPTTR for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter
has been tested.
