4.11.5 REVERSE POWER
If enabled, once the magnitude of 3-phase total power exceeds the Pickup Level in the reverse direction (neg-
ative 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.
