본 발명은, 차동 전류 측정 장치(22), 공급 네트워크 검출 장치(42; 45), 제어 장치(26), 증폭기(28), 보상 전류 선택 장치(36), 및 급전 장치(39, 41)를 구비한, 누설 전류를 보상하기 위한 보상 장치(20)에 관한 것이다. 공급 네트워크 검출 장치(42; 45)는, 활성 도체들(51, 52, 53, 54)과 연결된 공급 네트워크(L1, L2, L3, N)를 특성화하는 제2 신호(V_GRID; V_ES)를 발생시켜 제어 장치(26)에 공급하도록 구성된다. 보상 전류 선택 장치(36)는, 상기 공급을 위해 연결된 공급 네트워크에 적합한 하나 이상의 활성 도체(51, 54)를 선택하기 위해, 제3 신호(V_SEL)에 기반하여 적어도 2개의 상이한 활성 도체(51, 54) 중 적어도 하나에 보상 전류(I_COMP)를 공급하도록 구성되고, 상기 제3 신호(V_SEL)는 제2 신호(V_GRID; V_ES)에 좌우된다.

    A compensation device (20) for compensating for leakage currents has a differential current measuring device (22), a supply network detection device (42; 45), a control device (26), an amplifier (27), a compensation current selection device (36) and a feed-in device (39, 41). The supply network detection device (42; 45) generates a second signal (V_GRID; V_ES) characterizing the supply network (L1, L2, L3, N) connected to the active conductors (51, 52, 53, 54) and to supply it to the control device (26). The compensation current selection device (36) 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 (51, 54), and the third signal (V_SEL) is dependent on the second signal (V_GRID; V_ES) to select at least one active conductor (51, 54) suitable for the connected supply network for the feed-in operation.
