ISOMETER® isoHR685W

ISOMETER® isoHR685W

  • 10 GΩ measurement
  • Integrated web server and Modbus TCP communication
  • Early detection enhances operational safety and maintenance planning possibilities.
  • Synchronisation in systems coupled via capacitances
  • High adaptability to systems with different properties

The ISOMETER® is an insulation monitoring devices in accordance with IEC 61557-8 for IT systems. The devices are universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads (such as rectifiers, inverters, variablespeed drives).

A measuring range of up to 10 GΩ allows the trend of the insulation level to be recognised at an early stage. Therefore, the ISOMETER® is predestined for monitoring subsea cables in the oil and gas

industry.

  • ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems)
  • Automatic adaptation to the existing system leakage capacitance
  • Combination of AMPPlus and other profile-specific measurement methods
  • Two separately adjustable response value ranges of 1 kΩ…10 MΩ for alarm 1 and alarm 2
  • High-resolution graphic LC display for excellent readability and recording of the device status
  • Connection monitoring (monitoring of the measuring lines)
  • Automatic device self test
  • Graphical representation of the insulation resistance over time (isoGraph)
  • History memory with real-time clock (buffer for three days) for storing 1023 alarm messages with date and time
  • Current or voltage output 0(4)…20 mA, 0…400 μA, 0…10 V, 2…10 V (galvanically separated), which is analogous to the measured insulation value of the system
