Abstract

L'invention est relative à un déclencheur différentieL L'énergie prélevée sur le courant de défaut est accumulée dans un condensateur qui se décharge dans une bobine du déclencheur lorsque la tension aux bornes du condensateur dépasse le seuil d'une diode Zener en'l'occurrence environ 6,6 volts. Le déclencheur peut être utilisé pour la protection contre les défauts à la terre.
