Three-phase power meter
N10 series LUMEL

These meters ensure measurement and monitoring of 46 electrical quantities like: rms a.c. voltage and a.c. current, active, reactive and apparent power, active, reactive and apparent energy, different power factors, frequency, average active power ( e.g. 15 min). They also enable the control and optimization of power engineering electronic devices. Voltages and currents are multiplied by given ratios of voltage and current measuring transformers. Power and energy indications take into consideration the values of programmed ratios. These meters also indicate the real time.
Meters are used in computer systems e.g. LUMEL-ENERGY program for monitoring of power network parameters.
