A secondary circuit device including a secondary coil for transmitting and/or receiving magnetic energy of a magnetic field and converting the magnetic energy into electrical energy, a transmission unit for transmitting the electrical energy, a detection unit, and a damper circuit, wherein the magnetic field is generated by a primary coil of a primary circuit device; the transmission unit has an inlet for connecting the secondary coil; the transmission unit has an outlet for providing the electrical energy as voltage and/or current; the detection unit is connected to the inlet and/or the outlet of the energy transmission unit, in order to detect an overvoltage at the inlet and/or the outlet; and, when the overvoltage is detected, the detection unit is configured to influence the magnetic field in the secondary coil via the damper circuit such that a current jump and/or a voltage jump is brought about in the primary coil.
