Abstract:
An arc flash system for a circuit breaker and a method of operation is provided. The arc flash system includes a first sensor such as a photo-detector and a second sensor that detects a circuit breaker parameter. The arc flash system is responsive to signals from the first sensor and second sensor to determine if an arc flash event is occurring to avoid nuisance tripping of the circuit breaker.
