The invention relates to an insulation monitoring device that forms a measuring circuit with an unearthed IT power supply system for monitoring an insulation resistance, wherein the measuring circuit can be interrupted by a breaker device arranged in the insulation monitoring device. Furthermore, the invention relates to a method for performing an initial and/or repeated test of an insulation resistance in an unearthed IT power supply system and for monitoring the insulation resistance by means of an insulation monitoring device. For performing the initial and/or repeated test, the measuring circuit is interrupted by way of a manual switching act that activates a breaker device arranged in the insulation monitoring device.
An insulation monitoring device (IMD) that is installed between active conductors (L1, L2) of an IT power supply system (2) and a protective earth (PE) and forms a measuring circuit (8) with the unearthed IT power supply system (2) for monitoring an insulation resistance (RF),
A method for carrying out an initial and repeated test of an insulation resistance (RF) in an unearthed IT power supply system (2) and for monitoring the insulation resistance (RF) with an insulation monitoring device (IMD) that is installed between active conductors (L1, L2) of the IT power supply system (2) and a protective earth (PE), comprising the method steps of:
