In general, a breaker failure scheme determines that a breaker signaled to trip has not cleared a fault within a definite time,
so further tripping action must be performed. Tripping from the breaker failure scheme should trip all breakers, both local
and remote, that can supply current to the faulted zone. Usually operation of a breaker failure element will cause clearing of
a larger section of the power system than the initial trip. Because breaker failure can result in tripping a large number of
breakers and this affects system safety and stability, a very high level of security is required.
