GE-PQMII-T20
Functional Role & Application Analysis
The GE PQMII-T20 serves as a comprehensive power quality analyzer for continuous three-phase system monitoring. It is engineered to solve critical operational pain points: identifying the root cause of unexplained equipment failures, preventing capacitor bank resonance, and managing energy costs through precise demand tracking. The unit captures high-speed transient events and harmonic distortions that standard power meters simply miss.
Typical use cases for this module include:
- Industrial Manufacturing: Monitoring distribution feeders and motors to prevent harmonic-induced overheating and premature equipment failure.
- Utility & Substation Metering: Providing DNP 3.0 compliant data for SCADA integration, tracking power factor, and executing demand-side load shedding.
- Commercial Facilities: Logging voltage sags and swells to validate utility power quality claims and protect sensitive IT infrastructure.
Our Quality Standard & Testing Process
We understand that the cost of an unreliable part is far greater than its purchase price. A faulty power meter can lead to misallocated energy costs or missed fault diagnostics. We have established a rigorous, multi-stage testing process to ensure every PQMII-T20 we ship is 100% functional and accurately calibrated.
- Visual & Component Inspection: Every unit undergoes strict visual inspection to ensure no physical damage, LCD degradation, or compromised internal connections.
- Live System Test: The module is powered up in a live test environment and run continuously to verify stable operation, display functionality, and relay actuation.
- Full-Function Diagnostics: We simulate 3-phase voltage and current signals to verify metering accuracy, harmonic analysis, and communication port integrity.
- Warranty Backing: Only parts that pass all diagnostic tests are approved for shipment and backed by our full 12-month warranty, covering hardware and firmware failures.

Compatibility & Migration Paths
To ensure this PQMII-T20 is 100% compatible with your system, you must check these key compatibility points. Failure to verify this is a common project risk that leads to integration delays.
- Communication Protocol: Confirm your SCADA or EMS system supports DNP 3.0 or Modbus. The PQMII-T20 uses DNP 3.0 as its standard protocol.
- Power Supply Requirements: This unit requires a 18.5 to 36 VDC supply. Verify your control panel has an appropriate DC power source; it is not designed for direct AC mains power.
- Software Configuration: Ensure you have access to EnerVista setup software or equivalent configuration tools for relay setpoint programming and event log retrieval.
