ISOMETER® isoHV425 mit AGH422

  • Continuous insulation monitoring at a nominal system voltage of AC/DC 0 V … 1000 V
  • Galvanically separated interface allows predictive maintenance of the system being monitored
  • Measurement of nominal system voltages and partial voltages to earth
  • Automatic adjustment to the system leakage capacitance up to 150 µF
  • Indication of the insulation value distribution (conductors L1/+ and L2/-) in DC systems

The ISOMETER® monitors the insulation resistance of unearthed AC, AC/DC and DC systems (IT systems) with nominal system voltages of 3(N)AC, AC/DC 0 … 1000 V or DC 0 …1000 V. The maximum permissible system leakage capacitance Ce is 150 μF. DC components existing in AC systems do not influence the operating characteristics, when a minimum load current of DC 100 mA flows. A separate supply voltage allows de-energised systems to be monitored too.

In order to meet the requirements of applicable standards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions. Please heed the limits of the area of application indicated in the technical specifications. Any use other than that described in this manual is regarded as improper.
