1. A series arc detection system configured to detect series arcs in an input current waveform comprising:
a metering circuit configured to receive an input current waveform; and,
a controller including a power monitoring module configured detect series arc currents input current waveform by:
filtering the input current waveform to produce a filtered waveform;
performing feature recognition on the filtered waveform;
classifying one or more features of the filtered waveform identified during feature recognition;
performing temporal processing on the filtered waveform;
producing a score for the input current waveform based on the temporal processing of the filtered waveform; and,
reporting the score to a user based on a comparison of the score to a programmable threshold.
