Abstract
A method for detecting arcs in a DC circuit, having a detection conductor, which is routed at least along a conductor of the DC circuit, which carries an electric voltage and is to be monitored. In this connection, a voltage signal that refers to a potential of the DC circuit is coupled into the detection conductor at an incoupling point via a series resistor, the voltage signal is coupled out again at an outcoupling point of the detection conductor, the voltage signal before the series resistor is compared to the voltage signal at the outcoupling point, and a conclusion is drawn that an arc has occurred when the voltage signal at the outcoupling point deviates from the voltage signal before the series resistor by more than a predetermined amount. This invention also relates to a device for carrying out the method. The method and the device permit a quick, reliable detection of an arc in a DC circuit.
