Abstract
A compensation device () for compensating for leakage currents has a differential current measuring device (), a supply network detection device (), a control device (), an amplifier (), a compensation current selection device () and a feed-in device (). The supply network detection device () generates a second signal (V_GRID; V_ES) characterizing the supply network (L, L, L, N) connected to the active conductors () and to supply it to the control device (). The compensation current selection device () feeds in the compensation current (I_COMP) on the basis of a third signal (V_SEL) on at least one of the at least two different active conductors (), and the third signal (V_SEL) is dependent on the second signal (V_GRID; V_ES) to select at least one active conductor () suitable for the connected supply network for the feed-in operation.
