Abstract:
1. A circuit interrupter device comprising: a device current path comprising: a differential sensor, communicatively arranged and configured to read a current differential between the phase and neutral conductive paths and to output a differential sensor signal representative of a value of the current differential; a high frequency sensor communicatively arranged and configured to read a high frequency signal along one of the phase and neutral conductive paths and to output a high frequency sensor signal representative of a presence of the high frequency signal; a current sensor communicatively arranged and configured to read a current level along one of the phase and neutral conductive paths and to output a current level sensor signal representative of a value of the current level; and a processor configured to: (i) receive the differential sensor signal, the high frequency sensor signal, and the current level sensor signal, (ii) increment a count in a counter based on at least in part on the high frequency sensor signal, and (iii) detect a presence of an arc fault condition based on the count in the counter.
