Breaker Failure definition

Breaker Failure. Two independent primary and secondary breaker failure relaying systems provide redundant breaker failure protection. After a circuit breaker trip is initiated, the breaker failure relay will begin a countdown timer. If the circuit breaker fails to open within a specified period, then the breaker failure relay and its associated lockout relay will trip and block closure of an adjacent circuit breaker(s) and send direct transfer trip to the remote terminal station to isolate the stuck breaker. The relay shall be of utility grade and meet Transmission Owner’s standards. Transfer Trip: The breaker failure conditions at Transmission Owner terminals will be remotely tripped at the Xxxx Substation upon receiving direct transfer trip (DTT) signals from Xxxxxx and/or Plattsburgh substations. The breaker failure conditions at the Xxxx Substation will be remotely tripped at the Transmission Owner’s Terminal upon receiving DTT signals from the Xxxx Substation. The Phase II protection will be coordinated with the Xxxxxx Substation and the Plattsburgh Substation remote line relays.
