Title (EN) METHOD AND DEVICE FOR DETECTING AN ELECTRIC ARC IN A PHOTOVOLTAIC INSTALLATION
(FR) PROCEDE ET DISPOSITIF DE DETECTION D'UN ARC ELECTRIQUE DANS UNE INSTALLATION PHOTOVOLTAÏQUE
Abstract:
(EN) The photovoltaic installation being intended to supply an electric current (I), the method comprises the steps of measuring (E0) values representative of the electric current (I) supplied by the photovoltaic installation; adjusting (E2) a variable current jump threshold (S(ti)) according to measured values; detecting (E3) a current jump with an amplitude greater than a current jump threshold adjusted according to values measured before the jump; and detecting (E5) an electric arc based on the detection of a current jump.
(FR) L'installation photovoltaïque étant destinée à délivrer un courant électrique (I), le procédé comprend les étapes de mesure (E0) de valeurs représentatives du courant électrique (I) délivré par l'installation photovoltaïque, d'ajustement (E2) d'un seuil de saut de courant variable (S(ti)), en fonction de valeurs mesurées, de détection (E3) d'un saut de courant ayant une amplitude supérieure à un seuil de saut de courant ajusté en fonction de valeurs mesurées avant le saut et de détection (E5) d'un arc électrique sur détection d'un saut de courant.
