Abstract
A method and a monitoring device for selectively determining a partial system leakage capacitance in an ungrounded power supply system having a main system and at least one partial system. An extended insulation monitoring system is configured for determining an overall system leakage capacitance of the power supply system; an extended insulation fault location system for determining an ohmic and a capacitive partial test-current portion of a partial test current captured in the respective partial system; and an impedance evaluation system for determining a partial insulation resistance and a partial system leakage capacitance for each partial system to be monitored are provided. For preventing the entire ungrounded power supply system from being switched off, the fundamental idea of the present invention is advantageously based on identifying in which partial system a critical increase of a partial system leakage capacitance has taken place.
