Abstract
A method and device for insulation fault monitoring in ungrounded electrical networks. The method includes the following steps: measuring an insulation resistance, determining a responding value for the insulation resistance, and triggering a warning signal if the measured insulation resistance falls below the responding value, wherein the responding value is determined dynamically as a momentary responding value in a warning value establishment process downstream of the insulation resistance measurement.
