Abstract

L'invention concerne la protection des installations électriques. Dispositif de protection différentielle d'une installation électrique contre les courants de défaut à la terre, comportant un transformateur d'intensité muni d'un enroulement secondaire sur lequel est recueilli un signal de défaut destiné à commander le déclenchement d'un relais de coupure par l'intermédiaire d'un circuit d'amplification, caractérisé en ce que le circuit d'amplification comporte un circuit de mise en forme du signal recueilli, constitué par un filtre actif accordé sur une fréquence passante et fournissant un signal de forme sensiblement sinusoïdale malgré l'altération des signaux obtenus au secondaire, provoquée par la superposition de composantes continues aux courants de défaut primaires. Application aux installations électriques alimentées par un réseau alternatif.
