The electrical power meter, Xpert is a micro-controller based unit which measures various electrical parameters, and sequentially displays on a 128X64 backlit LCD.
The unit measures the three phase voltages, currents, frequency, power factors, individual Harmonic data as Histogram including Total Harmonic Distortion as well as individual current and voltage waveforms for all three phases. Based on these inputs, the system KVA, KW and KWh can also be calculated.
