- Low burden
APPLICATION
The relay provides under voltage protection of Motors, Generators, Capacitor Banks etc.
PRINCIPLE OF OPERATION
The Relay, JRV 022, provides under voltage protection for power systems. The Relay operating
time is determined by set definite time. The relay measures the voltage from input PT and if it falls below the set threshold, the relay extends a trip signal after the operating 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.
