APPLICATION
The relay provides Under and Over voltage protection of
Motors, Generators, Capacitor Banks etc.
PRINCIPLE OF OPERATION
The Relay, JRV 014, provides under & over voltage protection for power systems. The Relay operating time is determined by the set definite time. The relay measures the voltage from input PT and if the voltage is below the set threshold, under voltage stage operates and if the voltage is above the set threshold, over volt age stage operates and it extends a trip signal after the operat- ing time, which is determined by set definite time. The relay output contacts are self reset type. The TEST button facilitates testing of relay contacts for the trip and alarm circuits
