Abstract
Method for detecting an electric arc in a photovoltaic installation, which includes measurement (E) of voltage values at at least one site of the electrical circuit of the photovoltaic installation; digitization (E) of the measured voltage values so as to form voltage data; formation (E) of a window of n recent digitized voltage data; computation (E) of a test value associated with the said window of the n voltage data; analysis (E) of a test vector comprising m test values associated with m recent windows generating a quantity arising from this analysis representative of a risk of electric arc; comparison (E) of this quantity arising with at least one threshold so as to deduce therefrom the presence or otherwise of an electric arc within the photovoltaic installation.
