Westek Electronics Pty Ltd -
The Voltech PM3000A three- and single-phase Power Analyser is suitable for the measurement of all phase and line current and voltage parameters, total and displacement power factor, power and energy, comprehensive harmonics for voltage and current as well as short- and long-term flicker in compliance with IEC requirements.
The Voltech PM3000A Power Analyser locks on to the motor drive frequency of variable speed drives, making measurements over the full 1 MHz bandwidth and can compute drive efficiency through the input of torque/speed parameters and the instrument's ability to apply scaling factors.
The scaling factors of the Voltech PM3000A Power Analyser also make it suitable for power transformer testing and the determination of K factors in transformers used to supply high harmonic content loads.
The Voltech PM3000A Power Analyser through its software displays waveform, data logs, harmonic bar charts, cycle-by-cycle rms data, etc. The Voltech PM3000A Power Analyser utilises six monotonic A/Ds, three for voltage and three for current, the latter being equipped with high accuracy single shunts thus providing highly accurate frequency and phase performance. Digital signal isolation prevents errors typical of many analogue designs.
