The iso1685… 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.
