Abstract

Arcing faults are detected by a multi-channel arc fault detector in which each channel includes a bandpass filter having an assigned discrete passband which is non-overlapping with the passband of any of the other bandpass filters. Thus, the detector can discriminate an arcing fault which produces white noise and therefore generates an output from all of the bandpass filters simultaneously from a carrier signal which will only produce an output from one bandpass filter. The output of the individual bandpass filters can be ANDed, for example, by comparators with a common pull up resistor, or by analog multipliers. The output of the arcing fault detector can be used to trip a circuit breaker.
