摘要: The invention relates to a differential current monitoring device for monitoring differential currents in power supply systems, having a first measuring current transformer and having a measuring circuit for determining the differential current and having a computing unit for evaluating the differential current and for generating a switch-off signal. The differential current monitoring device has a device for detecting arcs, the integration of which according to the invention can considerably reduce the technical effort needed to monitor the differential current in connection with the arc detection in comparison to a functionally and spatially separate arrangement of both protective measures.
