Insulation monitoring of unearthed power supplies (IT systems) – VARIMETER IMD
Insulation monitors, also called IMD (Insulation Monitoring Device), monitor the insulation resistance in unearthed AC, AC/DC and DC power supplies (IT systems). This involves measuring the insulation resistance of the IT system to be monitored against earth. These systems are protected by insulation monitoring devices, the use of which is required by law in IT systems by the “Safety of Machinery” standard. Insulation monitoring devices are used to prevent accidents in the event of insulation faults, to prevent failures and generally to protect against fire and accidents.
