11.11.7.9
Three phase overcurrent LCP3PTOC (51)
Prepare the IED for verification of settings as outlined in section
for test"
in this chapter.
1.
Connect the test set for three-phase current injection to the appropriate IED terminals.
2.
Increase the injected current in phase A and note the operated value (pickup value) of the studied
step of the function.
3.
Decrease the current slowly and note the reset value.
4.
Connect a trip output contact to a timer.
5.
Set the injected current to 200% of the operate level of the tested stage. Switch on the current and
check the time delay.
6.
Check that all trip and pickup contacts operate according to the configuration (signal matrices).
7.
Finally check that pickup and trip information is stored in the event memory.
8.
Repeat steps 2 – 7 for phases B and C.
Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
11.11.7.10
Three phase undercurrent LCP3PTUC (37)
Prepare the IED for verification of settings as outlined in section
for test"
in this chapter.
1.
Connect the test set for three-phase current injection to the appropriate IED terminals.
2.
Inject a symmetrical three-phase current larger than the set value I<.
3.
Decrease the injected current in phase A and note the operated value (pickup value) of the studied
step of the function.
4.
Increase the current slowly and note the reset value.
5.
Connect a trip output contact to a timer.
6.
Decrease the injected current step-wise to 50% of the operate level and check the time delay.
7.
Check that all trip and pickup contacts operate according to the configuration (signal matrices).
8.
Finally check that pickup and trip information is stored in the event memory.
9.
Repeat steps 2 – 7 for phases B and C.
Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
