The service value output NSCURR indicating amplitude of negative sequence
current in primary amperes should be 962A approximative.

Completing the test

Continue to test another functions or end the test by changing the Test mode setting
to Off. Restore connections and settings to their original values, if they were
changed for testing purposes. Make sure that all built-in features for this function,
which shall be in operation, are enabled and with correct settings.
Accidental energizing protection for synchronous generator

Prepare the IED for verification of settings outlined in Section
to verify settings".

Verifying the settings

1. Connect the test set for three-phase current injection and for three phase
voltage injection to the appropriate IED terminals.
2. Inject zero voltage to the IED.
3. Increase the injected symmetric three phase current slowly and note the
operated value (start value) of the studied step of the function.
4. Decrease the current slowly and note the reset value.
5. Connect a trip output contact to a timer.
6. Set the injected current to 200% of the operate level of the tested stage,
switch on the current and check the time delay.
7. Check that all trip and start contacts operate according to the configuration
(signal matrises).
8. Finally check that start and trip information is stored in the event menu.
9. Inject rated symmetric three phase voltage to the IED.
10. Set the injected current to 200% of the operate level of the tested stage,
switch on the current. The function does not start and trip.
11. Inject 95% of the set ArmU< value symmetric three-phase voltage to the IED.
12. Set the injected current to 200% of the operate level of the tested stage,
switch on the current. The function does start and trip.
