12. Reverse the direction of the injected current and check that the protection does not operate.
13. Repeat the above-described tests for the higher set stages.
14. Finally check that pickup 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
Disabled under Main menu/Tests/IED test mode/1:TESTMODE. If another function is tested, then
set the parameter
OC4SPTOC(51_67,4I>)/1:OC4SPTOC for the function, or for each individual function in a chain, to
be tested next. Remember to set the parameter
has been tested.

Instantaneous residual overcurrent protection EFPIOC (50N)

Prepare the IED for verification of settings as outlined in section
settings".
Values of the logical signals for EFPIOC (50N) are available on the local HMI under Main menu/
Tests/Function status/Current/EFPIOC(50N,IN>>)/1:EFPIOC. The Signal Monitoring in PCM600
shows the same signals that are available on the local HMI.
To verify the settings the following fault type should be tested:
Phase-to-ground fault
Ensure that the maximum continuous current, supplied from the current source used for the test
of the IED, does not exceed four times the rated current value of the IED.
7.3.5.1

Measuring the operate limit of set values

1.
Inject a phase current into the IED with an initial value below that of the setting.
2.
Increase the injected current in the Ln or in the neutral (summated current input) phase until
the TRIP signal appears.
3.
Disable the fault current
Observe to not exceed the maximum permitted overloading of the current circuits in the IED
4.
Compare the measured operating current with the set value.
