  • Detection of electrical arcs in photovoltaic equipment
    Patent number: 9746528
    Abstract: A method for detecting a series arc in a photovoltaic device, operating in direct current mode, including N (N=1 or N>1) photovoltaic modules, connected to a charging device having a capacitive behavior for the modules, the method including: a) detecting, across n of the N modules (1?n?N), time evolution of voltage; b) identifying a voltage variation between a first zone of stable voltage and a second zone of stable voltage for a duration of at least 5 ?s, which immediately follows the voltage variation; and c) determining whether the voltage variation is between a value Vmin higher than or equal to 0.2 V and a value Vmax lower than or equal to 20 V, with rise time of the variation between a duration Tmin higher than or equal to 0.5 ?s and a duration Tmax lower than or equal to 5 ?s.
