ABSTRACT OF THE DISCLOSURE A method for the protection against the overloads in the cathode-mercury electrolytic cells, comprising detecting, in an indirect way, the average currents of the two semicells forming the cell to be protected by measuring the average of the anode potentials of the two semicells with respect to the two average potentials of the two semibottoms of the next cell, bridge connecting said two average potentials of the semicells with said two average potentials of the semibottoms of the next cell, obtaining, with balanced cell, two signals of bridge unbalance, by connecting in said bridge two double potentiometers having a single control, such as to actuate alarm devices when, because of overloaded anodes or of current unblanaces, the value of one of said signals is zero. A device is provided, for carrying out this method, comprising bridge electric circuits, with double potentiometer for working out signals, as well as of contact connected alarm thresholds for setting in action alarm and/or anode lifting devices.
