Abstract

a. L'invention a pour objet un dispositif pour déceler des variations de courant dans l'un ou l'autre conducteur d'un ensemble de conducteurs électriques. b. Le dispositif comprend un réseau de circuits résonnants saturables, associés chacun à un des conducteurs susdits, ledit réseau étant couplé à un organe de mesure de variations de la fréquence de résonance d'au moins un des circuits résonants. c. L'invention s'applique notamment au réglage de la position des anodes d'une cellule d'électrolyse à cathode de mercure, par détection des variations de courant dans les conducteurs d'amenée de courant aux anodes.
