The relay provides time graded phase and earth fault protection of Generators, Transformers, Feeder, capacitors etc.,
INVERSE TIME CURRENT RELAY JRC 068
Principle of Operation:
The relay measures the line current from each of the phases and if it exceeds the set threshold, then the relay extends a trip signal after an operating time. The relay's operating time is determined by selecting one of the four inverse time characteristics. The relay has facility to active / inhibit the high set protection feature. The relay output contacts are self reset / Hand reset type. Relay operation without any fault current can be test facility.
