Abstract
An arcing detection system that detects an output of noise superimposed on a voltage or a current of an electric circuit to which a load is connected, including a filter unit that extracts an output waveform in a high frequency band, and a phase division unit that determines a peak time domain including domains before and after a peak at a commercial frequency related to the output waveform extracted by the filter unit and a 0 value time domain before and after an output at the commercial frequency becomes a 0 value to distinguish between the peak time domain and the 0 value time domain. A determination unit determines an arcing event when an output in the peak time domain or a calculation value of the output in the peak time domain and an output in a 0 value time domain exceeds a threshold.
