6.15 FREQUENCY ELEMENTS (81O/81U)
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.
Set the relay as follows:
Apply voltage as indicated on the table, modifying frequency from the maximum threshold (48 Hz) to the minimum (46 Hz)
for 81U, and from the minimum (52 Hz) to the maximum (54 Hz) for 81O, in steps of 10 mHz.
Verify that the relay trips at the set frequency in the corresponding element with an error of 3% ó ±50 mHz.
Apply a voltage that is lower than the “Minimum Voltage” setting, with a frequency under (81U) or over (81O) the setting,
and verify that the relay does not trip.
