If enabled, once the magnitude of 3-phase total power exceeds the Pickup Level in the
reverse direction (negative kW) for a period of time specified by the Delay, a trip or alarm
will occur.
The minimum magnitude of power measurement is determined by the phase CT minimum
of 5% rated CT primary. If the level for reverse power is set below that level, a trip or alarm
will only occur once the phase current exceeds the 5% cutoff.
