10.1.14 FREQUENCY
The pickup and delay settings are dependent on operating practices and system characteristics. In this example, two over-
frequency and two underfrequency elements will be used. The elements will be blocked when offline. Underfrequency will
initiate a trip. Overfrequency will alarm only. Either source may be assigned.

10.1.15 ACCIDENTAL ENERGIZATION
In this example, the
ACCDNT ENRG ARMING MODE
is selected as “UV and Offline”. The
ACCDNT ENRG OC PICKUP
setting
should be set at ½ the minimum expected fault current. In this case, 1.0 pu (8000 A primary) is selected. In cases where it
is possible to re-energize the machine through its auxiliary transformer, a lower setting may be required. The undervoltage
pickup setting must be set above the maximum expected fault voltage.
