This article describes arc faults detection methods based on the temporal analysis of electric lines current signatures. We first give the, specifications of the domestical loads under test. Then, we describe the methods under test: crest factor, average value, variance, adaptive filter and mathematics moments. In the second part, these methods are implemented on MATLAB-Simulink. The analysis is done on the current for each period half cycle. The ability of arc faults detection is then presented for each algorithm.
