Abstract

L'invention concerne une interface permettant de couper l'alimentation électrique pour tout courant de défaut id = 300 milliampères tel que : id= ipe + k.Ih où ipe représente le courant revenant ô la source d'alimentation par le conducteur de protection reliant les masses ô la terre et ih ( = 10 ou 30 milliampères) représente le courant revenant ô la source d'alimentation autrement que par le conducteur de protection ou par un conducteur actif. Le courant ih est donc susceptible de traverser une personne. Ainsi, elle assure la protection des personnes et des biens contre les défauts d'isolement ô la masse et contre certains contacts directs indépendamment de la terre des masses et des conditions d'influences externes. Elle assure aussi la protection des personnes en cas de dysfonctionnement de la protection d'un voisinage utilisant la même terre en cas de défaut.
