"Power monitoring devices are intended for measuring, analysing and monitoring of single-phase or three-phase electrical power network of electricity distribution and energy production companies, utilities, dwellings, industry, business buildings, designers of small power stations, etc.
The meter records 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, phase angles, etc.) from the measured signals.
Free software tool Miqen included. Miqen is a user –friendly toll for complete monitoring of the measuring instruments."
