Abstract

a. Branchement de protection contre les courants de fuite pour courant continu et/ou alternatif. b. Branchement caractérisé en ce que l'enroulement auxiliaire du transformateur de courant total revêt la forme d'une bobine de mesure, cette bobine de mesure ainsi que la source de courant se situent à l'entrée d'un organe de filtration, un organe redresseur est branché en aval de l'organe de filtration, l'organe redresseur est relié par l'intermédiaire d'un amplificateur différentiel avec un organe semi-conducteur susceptible d'être commandé, l'organe semi-conducteur susceptible d'être commandé est branché en parallèle sur le palpeur du circuit de contrôle. c. L'invention s'applique notamment à la protection des appareils électriques domestiques.
