Set the relay to trip for the protection element being tested. Configure any of the outputs to be enabled only by the
protection element being tested.
Apply 0.9 times the Pickup current and check that the relay does not trip.
Gradually increase the current value and verify that the relay operates between 1 and 1.1 times the set pickup current. The
relay must trip by instantaneous in a time frame of 10 to 55 ms. All the relay trip contacts must operate, as well as the
contact set as 50.
Remove current and apply it again suddenly to a value of 4 times the pickup current. The relay should trip instantaneously
in a time frame of 10 to 45 ms.
Test one point for each phase and group of the protection element.
