ABSTRACT:
A circuit protection system is provided that provides a dynamic delay time to an upstream circuit breaker if a fault is detected in a circuit where the dynamic delay time can be based upon the location of the fault, such as the nearest downstream circuit breaker. A control processing unit can determine a dynamic delay time for opening a first circuit breaker if a fault is detected in the circuit. The control processing unit delays opening the first circuit breaker until after the dynamic delay time has elapsed to provide an opportunity for the nearest circuit breaker to clear the fault.
