Abstract

Détection de courants forts. Un circuit magnétique 3-4 traversé par une barre conductrice 1 qui l'excite est protégé contre les champs magnétiques parasites par deux écrans plats 11, 12 en matière ferromagnétique perméable mais non saturés disposés de part et d'autre du circuit Protection et sécurité contre les courts-circuits et les déséquilibres des courants forts spécialement en traction électrique.
