The PQM II is an ultra-versatile power quality meter designed for the comprehensive monitoring and analysis of three-phase power systems. It excels at providing real-time metering, power quality analysis (including THD and individual harmonics), and data logging for industrial feeders and motor control centers. With its high-speed sampling and programmable setpoints, the PQM II serves as both a high-accuracy revenue meter and a predictive maintenance tool, alerting operators to power disturbances before they result in equipment damage or costly downtime.
Product Comparison: PQM II vs. EPM Series
The PQM II is a specialized tool within the GE Multilin portfolio, offering distinct advantages over basic electronic power meters like the EPM 2200 or EPM 6000:
- Waveform Capture: While EPM series meters typically provide basic RMS values, the PQM II can capture high-resolution waveforms of disturbances, allowing for deep-dive post-fault analysis.
- Analog Integration: The PQM II features significantly more robust analog I/O options (up to 4 inputs/outputs), making it a superior choice for integrating non-electrical signals like temperature or pressure into the power management system.
- Harmonic Detail: Compared to entry-level meters, the PQM II offers advanced harmonic distortion calculations up to the 32nd order, which is essential for troubleshooting issues in facilities with high non-linear loads like VFDs.
