ARC DETECTION WITH AVOIDANCE OF NUISANCE ACTIVATION THROUGH LIGHT SUBTRACTION

In an electrical distribution system having an arc management system for removal of arcing voltage from feeder circuits triggered at least in part by light signals, a secondary optical detector monitors a downstream branch circuit breaker in the feeder circuit compartment to produce an optical signa...

Summary:In an electrical distribution system having an arc management system for removal of arcing voltage from feeder circuits triggered at least in part by light signals, a secondary optical detector monitors a downstream branch circuit breaker in the feeder circuit compartment to produce an optical signal for arc detection more accurately reflecting the possibility of an arcing fault.
