This is designed to monitor 3-phase supplies and to protect motors
and other loads against the faults listed below.
Monitoring of rotational direction of phases Detection
of complete failure of one or more of the phases Undervoltage
detection (-10%) Overvoltage detection (+10%) Detection
of phase asymmetry (imbalance) (±10%) The relay operates if
any of the conditions occours. The relay releases if any of the
conditions fails. There is a Time Delay between the relay action
and the condition occours (except rotational direction of phases
error) to avoid very short interruptions or other momentary
failures. A selector switch allows selection of an adjustable time
delay from 0.1 s to 10 s. When the supply returns towards its rated
value, the relay is re-energised according to the hysteresis value
