Abstract
The invention relates to a circuit assembly for the state monitoring and logging of overvoltage protection devices or overvoltage protection systems by means of pulse current monitoring, comprising at least one passive RFID transponder having an inductively coupled voltage supply, wherein in the case of an event of the overvoltage protection device or the overvoltage protection system, the RFID transponder antenna circuit is influenced, in particular interrupted, short circuited, or detuned, so that disturbance processes can be identified. According to the invention, a coil Lis provided on a discharge line of the overvoltage protection device or the overvoltage protection system that carries pulse currents that occur, which coil Lis oriented in such a way that the field caused by pulse current passes through the coil winding surface, wherein the coil Lis connected to at least one switching device, which is connected on the antenna circuit of the RFID transponder to the inductor Lthere in order to influence the antenna circuit at least at times.
