ZV FREQUENCYOnce the frequency of the phase AN or AB voltage (depending on wye or deltaconnection) is out of range of the overfrequency and underfrequency setpoints, atrip or alarm will occur.This feature may be useful for load shedding applications on large motors. It couldalso be used to load shed an entire feeder if the trip was assigned to an upstreambreaker.
