Application
The auto reclose function is normally used in feeder protection relays that are protecting an overhead line. Most of the
overhead line faults are temporary in nature. Upto 85% can
be cleared by using the auto reclose function.
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 the consumer cannot notice anything.
However, the fault will 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.
