摘要
In an electrical distribution system an arc management system has a transducer 27 mounted in proximity to the circuit breaker 26 for detecting and signaling a secondary effect of an overcurrent event within the case 25 of the circuit breaker. The transducer provides an additional input to an arc fault detection system using other detectors and thus helps to control nuisance activations of the arc extinguishing mechanism. The system is particularly suited for circuit breakers without electronics, or the like, allowing for retrofit of existing systems. The system may monitor and act upon the excessive duration of the secondary effects.
