Device overview

The device is a digital insulation monitoring device (IMD) for low-voltage ungrounded power systems. The device monitors the insulation of a power system and notifies any insulation faults as soon as they occur.

IMD applies low-frequency AC voltage between the power system and the ground to provide accurate insulation monitoring in complex applications. The insulation is then assessed on the basis of the current value returned. This method is used for all power system types - AC, DC, combined, rectified, with a variable speed drive, etc.

IM10 and IM20 offers the following features:

  • Insulation resistance display (R)

  • Detection of insulation faults in accordance with a configurable threshold

IM20 offers these additional features:

  • Leakage capacitance display (C) with associated impedance (Zc)

  • Communication via the Modbus RS-485 protocol

  • Injection inhibition via logic input

  • Insulation fault log
