Abstract

Procédé de détection de courant de défaut différentiel pour la protection contre les courants de défaut à la terre dans les circuits d'alimentation électrique continus ou alternatifs. Il consiste à mesurer en permanence les variations de la valeur de l'inductance d'un enroulement secondaire d'un trans formateur différentiel dont les enroulements primaires sont parcourus par les courants des conducteurs du circuit à proté ger. Application notamment à la protection contre les courants électriques de défaut à la terre.
