摘要： A compensation apparatus compensates for leakage currents on conductors that include active conductors. The apparats (20) has a differential current measuring apparatus (22), a power supply unit (60), a first signal generator (33), an output stage (28) and a supply apparatus (39). The differential current measuring apparatus (22) captures a first signal at a first location of the active conductors and supplies it to the first signal generator (33). The first signal characterizes differential current on the active conductors. The first signal generator (33) generates a second signal to compensate for the differential current from the first signal and supplies this second signal to the output stage (28). The output stage (28) injects a compensation current into at least one of the active conductors via the supply apparatus (39) on the basis of the second signal.

摘要： A device for filtering at least one signal has a first magnet core and at least one first coil. The first coil has a first coil connection, a second coil connection, a first coil element, a second coil element and a connecting section. The first coil connection is electrically connected to the second coil connection via the first coil element, the connecting section and the second coil element. The first coil element has a first coil axis and the second coil element has a second coil axis. The first coil axis and second coil axis are arranged parallel to and at a distance from one another. The first magnet core extends both through the first coil element and also through the second coil element.

摘要： 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.

摘要： A rectifier arrangement for rectifying an AC voltage into a DC voltage has connections, circuit arrangements, an interconnection apparatus and an intermediate circuit. Each circuit arrangement has first and second circuit arrangement connections, between which a changeover arrangement and a coil are connected in series with the changeover arrangement. The changeover arrangements are interconnected to the intermediate circuit. The interconnection apparatus is designed to enable at least a first configuration and a second configuration. In the first configuration, the circuit arrangements form a first group and a second group, with two connections connected to the circuit arrangements in the first group, but not to the circuit arrangements in the second group, and two connections are connected to the circuit arrangements in the second group, but not to the circuit arrangements in the first group. In the second configuration, at least one of the connections is connected to all circuit arrangements.

摘要： A monitoring device for monitoring leakage currents at active conductors has a differential current measurement device, a signal generation device and a control device, which differential current measurement device is designed to record a first signal (I_DIFF) characterizing the differential current of the active conductors and to feed the first signal to the control device. The signal generation device is designed to generate at least one second signal (V_GRID) and to feed the second signal to the control device, which at least one second signal (V_GRID) includes information about the phase angle of a signal occurring at one of the active conductors. The control device is designed to generate a third signal (I_LC_RES) on the basis of the first signal (I_DIFF) and of the at least one second signal (V_GRID), which third signal characterizes the resistive leakage current.
