AUTO RECLOSE RELAY WITH FAST RESET JRV 142

Principle of Operation:

The relay receives the fault initiation from the protection relay and that triggers the auto reclose function. After tripping the circuit breaker (CB), the Auto reclose function can reclose the CB. Normally , the first reclose (or shot) is so short in time that consumer cannot notice anything . However the fault is cleared and the feeder will continue in normal service. Even though the basic principle of Auto reclose is simple, there are a lot of different timers and parameters that have to be set.
