ISKRA‘s iMC750 NETWORK RECORDER is an essential device for permanent monitoring measuring and analyzing single-phase or three-phase electrical power networks.

The meter measures the 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 performs measurements in compliance with regulatory requested standard EN 61557-12.

All required measurements and Alarms can also be stored locally in 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 to monitor, measure and record electrical quantities of a three-phase electric-energy distribution system.

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

Features

-Measurements of instantaneous values of more than 140 quantities including harmonics, power line signaling voltage, unbalance, etc..
