Product Introduction
The PQMII GE is a versatile 3-phase power meter designed to provide more than just basic energy readings; it acts as a diagnostic tool for the entire electrical distribution network. By providing detailed data on total harmonic distortion (THD) and waveform disturbances, it allows maintenance engineers to identify the root causes of equipment overheating or nuisance tripping before they lead to catastrophic failure.
In many utility-scale deployments, the PQMII GE is prized for its “set it and forget it” reliability. It integrates easily into SCADA systems via Modbus, providing real-time visibility into power factor, demand, and load profiles. When sourcing this unit, verify if your application requires the “T” (Transducer), “C” (Control), or “A” (Advanced) options, as these drastically change the available analog outputs and alarm relay configurations.
Key Selling Points & Differentiators
- Revenue-Grade Accuracy: Features 0.2% accuracy for voltage and current, making it suitable for internal sub-billing and precise load studies.
- Transient Disturbance Recording: Captures voltage sags and swells with a resolution of 64 samples per cycle, providing forensic data for power quality events.
- Modular Option Boards: The PQMII GE can be outfitted with various I/O cards to provide up to four 4–20 mA analog outputs for PLC integration.
- Not Recommended For: Direct high-voltage connection without proper Potential Transformers (PTs); always use the correct ratio scaling in the settings.
- Standard Compliance: Meets IEEE 519 standards for harmonic monitoring and control in industrial power systems.
