Abstract
A combined monitoring device for insulation-resistance monitoring and protective-conductor-resistance monitoring in a power supply system includes a grounded power supply system and an ungrounded power supply system, the combined monitoring device having a coupling circuit for being coupled to one or several active conductors of the grounded power supply system via coupling points, the combined monitoring device including an active monitoring device with a first operating mode for monitoring an insulation resistance in an ungrounded network state of the power supply system and a second operating mode for monitoring a protective-conductor resistance in a grounded network state of the power supply system, the combined monitoring device having an evaluation unit switchable between the first and second operating modes as a function of the ungrounded or grounded network state and configured for testing the insulation resistance in the first operating mode and the protective-conductor resistance in the second operating mode.
