A compensation device for compensating leakage currents has a differential current measurement device, a first signal generation device, an amplifier and a feeder device. The first signal generation device is designed to generate a first compensation current specification signal (I_COMP_S1) suitable for the compensation from the first signal (I_DIFF) from the differential current measurement device by way of analog signal processing and to feed this first compensation current specification signal (I_COMP_S1) to the amplifier in analog or digitized form. The amplifier is designed to generate a compensation current (I_COMP) on the basis of the first compensation current specification signal (I_COMP_S1), and the feeder device is designed to allow the compensation current to be fed in at at least one of the active conductors.
