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.

Caratteristiche
- 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…3 GΩ 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
- Freely programmable digital inputs and outputs
- Remote setting via the Internet or Intranet (Webserver/Option: COMTRAXX® Gateway).
