Testing functionality by secondary injection
1. Connect the test set for the appropriate three-phase current injection to the
IED phases L1, L2 and L3. The protection shall be fed with a symmetrical
three-phase current.
2. Set the injected current to 113% of IBase, switch on the current and check
operate time of the trip, 120 s.
3. Decrease the current slowly.
4. The output signal START will reset if the measured current falls below reset
level or if BLOCK signal is set to one.
5. Switch off the current.
6. Set the injected current to 125% of IBase, switch on the current and check
operate time of the trip, 60 s.
7. Switch off the current.
8. Set the injected current to 146% of IBase, switch on the current and check
operate time of the trip, 30 s.
9. Switch off the current.
10. Set the injected current to 209% of IBase, switch on the current and check
operate time of the trip, 10 s.
11. Switch off the current.
12. Set the injected current to 100% of IBase and switch on the current.
13. Decrease the current slowly under I<.
14. The signal TRIPUC will be activated when timer tTrip_I< expires.
15. Finally check that start and trip information is stored in the event menu.
Testing the protection

Completing the test

Continue to test another function 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.
