The insulation monitor AN 5873 of the series VARIMETER IMD monitors the ground resistance of ungrounded DC and 3-phase AC voltage systems (IT-systems) with nominal voltage up to DC 0 ... 1000 V and 3 AC 24 ... 690 V. The unit detects symmetrical as well as unsymmetrical faults. The separate auxiliary supply allows also monitoring when the system is without voltage. To indicate the actual ground resistance value the unit has an LED chain and an analogue output. When a fault is detected the relay switches and the red LED lights up.
