METHOD FOR DETECTING AN ELECTRIC ARC IN PHOTOVOLTAIC EQUIPMENT

摘要

The invention relates to a method for the ultrasound detection of an electric arc in a photovoltaic device, characterised in that the method includes the following steps: measuring (E1) at least one parameter of a signal received by an ultrasound sensor (6) from among the amplitude of the signal, the duration of the signal, and the central frequency of the signal; comparing (E2) the measurement of said at least one signal parameter with predefined values to determine whether or not the measurement corresponds to that of an electric arc.
