Abstract

A method for reducing leakage currents in a protective conductor of an electricity network including a neutral conductor and a phase conductor in addition to the protective conductor. A differential current is determined depending on a phase conductor current in the phase conductor and a neutral conductor current in the neutral conductor. A compensation current is fed into the phase conductor and/or into the neutral conductor. The compensation current compensates for a leakage current caused by the differential current. Also described is a device for carrying out such a method.
