NETWORK RECORDER iMC750

iMC750 Network Recorder is an important device for permanent monitoring measuring and analysing single-phase or three-phase electrical power network.

The meter measures TRMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from the measured signals.

  • iMC750 perform measurements in compliance with regulatory requested standard EN 61557-12.
  • All required measurements and Alarms can also be stored locally in an internal memory. With the RS232/RS485 or Ethernet/USB communication the meter can be set, measurements checked, and stored data downloaded.
  • iMC750 Network recorder is intended for monitoring, measuring and recording of electrical quantities of a three-phase electric-energy distribution system.

Identifying relevant fixed measuring points is the most important task prior to complete system installation. This system itself will not prevent disturbances in network but it will help diagnose their origin and effects. This is possible only with system approach by using time-synchronized meters with a wide range of measuring parameters.
