11.
Connect the trip output to a timer.
12.
Have inputs CR! and CR2 activated. Start the timer from activation from activation of input LOCTR
and stop the timer from TRIP output.
13.
Check the trip time.
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.

Negative sequence overvoltage protection LCNSPTOV (47)
Prepare the IED for verification of settings as outlined in section
for test"
in this chapter.
11.11.7.6
Zero sequence overvoltage protection LCZSPTOV (59N)
Prepare the IED for verification of settings as outlined in section
for test"
in this chapter.
1.
Connect the test set for three-phase voltage injection (A, B, C) or residual voltage injection (N) to
the appropriate IED terminals. This depends on how the IED is fed from the VT.
2.
Increase the injected zero sequence voltage and note the operated value (pickup value) of the
studied step of the function.
3.
Decrease the voltage slowly and note the reset value.
4.
Connect a trip output contact to a timer.
5.
Set the injected voltage to 110% of the operate level in 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.
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.
