Abstract
A method of detecting an electric arc in an electrical system from a signal originating from at least one sensor detecting acoustic waves in the system, including: a) calculating by means of a processing device, over a sliding window of signal samples, at least one statistical parameter selected from the skewness and the kurtosis of the signal; b) detecting a possible occurrence of an event by taking into account said at least one statistical parameter; and c) performing a frequency analysis of the signal enabling to identify an electric arc when an event is detected at step b).
