Abstract
Exemplary embodiments are directed to a device with overvoltage protection that includes a varistor which can be connected by a first connection via a first line to high-voltage potential in a circuit arrangement, while a second connection is connected to ground via a second line. Furthermore, an additional impedance is provided, which can be connected between the second connection and ground or the first connection and the high voltage, or is mounted fixed in this position. The corresponding line can be interrupted by a switching arrangement. In order to test the withstand voltage of the circuit arrangement, at least one of the first and second line is interrupted and an additional impedance is inserted. A test voltage is applied to the circuit arrangement. After the overvoltage test, the interruption in at least one of the first and second lines is removed again.
