Zusammenfassung:A circuit and process for disconnecting the current from the operating gap of an electrolytic processing device in the event of a short circuit in which a signal is produced from the AC current in the transformer supplying power to the gap, such signal indicating the gap current, the maximum value of that signal is stored for successive time periods and the stored value for a preceding period compared with the present signal to operate a switch in the current supply to the gap when a short circuit condition is detected.
