ISOMETER® iso1685P

ISOMETER® iso1685P

  • Insulation monitoring device for AC 1000 V and DC 1500 V IT systems
  • Application main circuits with connected frequency converters
  • Separately adjustable response values 200 Ω…1 MΩ
  • Display and control function for EDS insulation fault location systems
  • Can be extended to operate as an insulation fault location system

The iso1685P is used for insulation monitoring of extensive systems

up to AC 1000 V/DC 1500 V which are designed as IT systems. The device

uses a specially developed measurement method for monitoring the

insulation resistance also in extensive installations where extremely

high leakage capacitances against earth exist due to interference

suppression methods. Adaptation to systems containing high leakage

capacitances occurs automatically.

The device generates locating current pulses required for insulation

fault location. That allows the localisation of the insulation fault

using permanently installed or mobile insulation fault locators.
