Abstract
A method and an insulation monitoring device for insulation monitoring with network balancing in an ungrounded direct voltage system involves a measurement of conductor-to-ground voltages by means of voltage measuring devices; a computation of insulation resistances specifically for a conductor; and a compensation of an asymmetrical voltage between the conductor-to-ground voltages by means of a control circuit. A combination of an insulation monitoring function and network balancing based on a digital control circuit with the degree of asymmetry (asymmetrical factor) as control variable is provided. The asymmetrical voltage is compensated permanently via a suitable assessment of a (voltage) control error by means of a controller, and the resistance setting value required therefor is detected as a manipulated variable for one of the variable resistances.
