Abstract

a. Installation de détection de surintensités de courant dans les phases d'un réseau. b. Installation caractérisée par un redresseur 13, 14 créant des tensions redressées proportionnelles aux extrémités de chaque phase, un émetteur pour des signaux correspondant à ces tensions pour un redresseur alimentant des moyens de détection, un ensemble de moyens de limitation de tension 23, 33, 43 en parallèle sur les moyens de détection et recevant une tension continue pour effectuer des comparaisons de seuil sur les moyens de détection et créer le cas échéant un signal de protection. c. L'invention s'applique à la protection des réseaux de distribution de courant.
