In unearthed power supplies (IT systems), none of the active conductors is directly connected to earth. Therefore, on the occurrence of an insulation fault, only a small leakage current, essentially caused by system leakage capacitances, can flow. The upstream fuse does not trip, hence continuous power supply and operation is ensured. Prompt information about possible hazards is given by the ISOMETER® which continuously monitors the insulation resistance between the system and earth. We have the right solution for each application.
