7.6.7.4 A18 IMD – Insulation Monitoring Device
The IMD supplements is an insulation monitoring for mobile generators. It monitors the
insulation resistance RF of an unearthed AC system of 0V up to 300 V to earth that is
supplied by a mobile generator. The currently measured insulation resistance is
indicated on the LC display. In this way, any changes, for example, when circuits of
loads are connected to the system, can be recognized easily. The maximum permissible
system leakage capacitance Cemax is 5 μF.
The IMD is useful to comply with the German legislation. It is use in many kind of
applications:
- IEC 60364-7-717, DIN VDE 0100-717 (2005) Electrical installations in mobile or
transportable units
- DIN VDE 0100-551 (VDE 0100-551), IEC 60364-5-551 Low-voltage generating sets
(mobile generators)
- GW 308 “Mobile Stromerzeuger für Rohrleitungsbaustellen 8/00” (Mobile auxiliary
power generators on pipeline site”) (DVGW)
- BGI 867 (German Berufsgenossenschaft Information) Auswahl und Betrieb von Ersatzstromerzeugern auf
Bau- und Montagestellen (Selecting and operating standby generators on construction and installation sites).
Operating elements:
