Insulation fault location during operation in unearthed power supplies (IT systems) – VARIMETER EDS
A device for insulation fault location, also called IFLS (Insulation Fault Location System), enables insulation faults to be located within a very short time and is used in addition to an insulation monitor. In the event of a fault, it impresses a test current between the live conductors and earth. Components that are pre-damaged with regard to insulation can be located as quickly as possible and replaced before a failure occurs, i.e. there is no need to shut down the system.
