Abstract

Dispositif de protection comportant un premier et un second transformateurs différentiels ayant chacun un noyau magnétique torique à travers lequel passent les conducteurs neutre et de phase d'un réseau de distribution de courant alternatif et un enroulement secondaire, l'enroulement secondaire du premier transformateur étant relié à l'entrée d'un amplificateur suivi d'un redresseur, d'un comparateur à seuil et d'un organe de commande apte à déclencher un coupe-circuit, tandis que l'enroulement secondaire du second transformateur est relié à la sortie dudit amplificateur, caractérisé par un amplificateur auxiliaire, inséré entre la sortie du premier amplificateur et les bornes de l'enroulement secondaire du deuxième transformateur différentiel. Application à la protection d'une prise de courant.
