What is the function of an Auto reclosure relay. How does it
work??
Answer Posted / satyendra8714
If single phase fault (any one particular phase to ground fault) exist in the transmission line AR will operate. But single phase fault should be in zone-1 of the protected line. Then only AR will perform. If fault is in transient in nature then particular line breaker will open and wait for dead time after that breaker will reclaim if fault is cleared then no problem other wise differential relay will initiate three pole trip. This AR is mainly to minimize the outages.
