Abstract
A monitoring device for monitoring leakage currents at active conductors has a differential current measurement device, a signal generation device and a control device, which differential current measurement device is designed to record a first signal (I_DIFF) characterizing the differential current of the active conductors and to feed the first signal to the control device. The signal generation device is designed to generate at least one second signal (V_GRID) and to feed the second signal to the control device, which at least one second signal (V_GRID) includes information about the phase angle of a signal occurring at one of the active conductors. The control device is designed to generate a third signal (I_LC_RES) on the basis of the first signal (I_DIFF) and of the at least one second signal (V_GRID), which third signal characterizes the resistive leakage current.
