Totally wireless interiors, choice of screw less terminals, ±2% accuracy, test and auto/manual reset facility are the other features. These Voltage Relays have wide application in protection of generators and AMF switch boards, in protection of synchronous and induction motor, in transformer feeder panel, for protection of capacity control panel, in UPS protection under abnormal voltages.
