Abstract

Ce dispositif concerne l'alimentation de filtres de courant dans des relais électriques, tels que relais de lignes, relais de génératrices, relais de moteurs ou similaires. Il est raccordé à un circuit redresseur alimenté par un transformateur d'intensité; les entrées 13, 14 d'un amplificateur opérationnel 12 sont raccordées à l'une des extremités de resistance respectives 9, 10 du circuit redresseur, l'autre extrémité de chaque résistance étant raccordée au conducteur neutre 16, et le filtre 18 est alimenté par la sortie de l'amplificateur opérationnel.
