摘要：
The invention relates to a method and an apparatus for determining an actual insulation resistance RISO in IT systems grounded with a functional grounding resistance RHRG, comprising constant insulation monitoring. In one embodiment of the invention, the functional grounding resistance RHRG is determined during the initial inspection of the IT system, determining a total insulation resistance Rges is carried out during the constant insulation monitoring, and the actual insulation resistance RISO is determined during the operation of the IT system from the functional grounding resistance RHRG and the total insulation resistance Rges.
