6.11 TIME OVERCURRENT (51PH, 51PL, 51N, 51G)
Set the relay to trip for the protection element being tested. Configure any of the outputs to be activated only by the
protection element being tested.
Apply 0.9 times the Pickup current and check that the relay does not trip.
Apply 1.5 times the Pickup current. The relay should trip according to the time corresponding to its set curve.
Apply 5 times the Pickup current. The relay should trip according to the time corresponding to its set curve.
