Abstract
L'invention concerne un détecteur de défaut de masse. Selon l'invention, il comprend un capteur d'un défaut de masse se produisant dans une ligne en courant alternatif pour produire un courant détecté, un amplificateur connecté au capteur, un circuit retardateur 18 connecté à l'amplificateur, un circuit formeur d'onde 40, 42, 52 connecté au circuit retardateur 18 et un élément de commutation sensible à la sortie du circuit formeur d'onde pour être conducteur, le circuit formeur d'onde ayant un circuit à courant constant pour diminuer les courants de fonctionnement s'écoulant à travers l'amplificateur et le circuit retardateur à l'état passant du circuit formeur d'onde et appliquer au moins une partie du courant diminué sous forme un courant constant à l'élément de commutation. L'invention s'applique notamment à une utilisation avec un interrupteur de courant de fuite.
