Abstract
A photovoltaic installation comprising at least one photovoltaic module () and an electromechanical unit capable of producing a non-stray electric arc of a duration less than or equal to a given arc-quenching duration (x) when contacts of the electromechanical unit are opened. The photovoltaic installation comprising a method comprising the steps of: detecting (E) the appearance of an electric arc in a photovoltaic installation; triggering (E) a timer to start timing from the moment (T) of appearance of an electric arc; measuring (E) at least one of electric quantities of a group including a voltage (V) of the at least one photovoltaic module and a current (I) produced by the photovoltaic installation at the end of the arc-quenching duration starting from the moment (T) of appearance of the electric arc; comparative testing (E; E) in order to determine whether the measured electric quantity is equal to an open-circuit voltage (V) of the photovoltaic module or to a zero current; and, if the test is negative, identifying a stray electric arc.
