Section 10
Testing functionality by secondary injection
4. If the test has been performed by injection of current in phase A, repeat the test, injecting current
into phases B and C with polarizing voltage connected to phases B, respectively C (1 out of 3
currents for operation).
5. If the test has been performed by injection of current in phases AB, repeat the test, injecting current
into phases BC and CA with the appropriate phase angle of injected currents.
6. Connect a trip output contact to a timer.
7. Set the injected current to 200% of the trip level of the tested stage, switch on the current and
check the time delay.
For inverse time curves, check the trip time at a current equal to 110% of the trip current for txMin.
8. Check that all trip and pickup contacts trip according to the configuration (signal matrixes).
9. Reverse the direction of the injected current and check that the protection does not trip.
10. If 2 out of 3 or 3 out of 3 currents are chosen for operation: Check that the function will not trip with
current in one phase only.
11. Repeat the above described tests for the higher set stages.
12. Check that pickup and trip information is stored in the event menu .

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.
