An exemplary method is disclosed for disturbance current compensation for an electrical system by a disturbance current compensation device, which electrical system has a voltage source and a series circuit which is connected via a conductor in parallel with the voltage source. The series circuit has an inductance and a capacitance, with the inductance being connected in series with the capacitance via a conductor. To compensate for disturbance currents, the conductor for the connection of the voltage source to the series circuit of the inductance with the capacitance, and/or the conductor of the series circuit between the inductance and the capacitance, can be surrounded by a ring (e.g., a portion of the conductor can be substantially surrounded by the ring) which can be magnetized. The ring includes an air gap of the disturbance current compensation device. A compensation voltage can be applied by magnetization of the ring. The ring can be magnetized by a magnetization coil of the disturbance current compensation device.
