Comprehensive Power Quality Analysis:
Measures over 50 parameters, including real/reactive/apparent power, energy consumption, and THD (Total Harmonic Distortion). Its FFT-based harmonic analysis identifies waveform distortions caused by nonlinear loads (e.g., variable frequency drives) . -
Waveform Capture and Event Logging:
Records voltage/current waveforms during transients (e.g., voltage sags/swells) and stores up to 150 events with timestamps. This capability is critical for troubleshooting equipment failures in manufacturing lines or data centers . -
Programmable Control and Alarms:
Four assignable output relays enable automated actions like load shedding or capacitor bank switching to correct power factor issues. Users can configure thresholds for parameters like overvoltage or harmonic levels . -
Industrial-Grade Reliability:
Withstand extreme temperatures, humidity, and EMI/RFI interference. Its IP20-rated design ensures durability in harsh environments such as outdoor substations or mining facilities . -
Seamless Integration:
Supports Modbus RTU and optional Ethernet connectivity, allowing integration with SCADA systems, IoT platforms, and GE’s Enervista software for remote monitoring and analytics .
Application Scenarios
- Industrial Automation: Monitors power quality in automotive assembly plants to prevent downtime caused by voltage instability in robotic systems .
- Renewable Energy: Optimizes solar/wind farm performance by analyzing grid synchronization issues and harmonic distortions from inverters .
- Utility Substations: Ensures compliance with IEEE 1159 standards by continuously monitoring voltage flicker and transient events in medium-voltage networks .
- Critical Infrastructure: Protects data centers and hospitals from power disruptions by triggering alarms during voltage sags that could affect UPS systems .
Related Models and Alternatives
- GE PQMII-T20-C-A: Enhanced variant with 4–20 mA analog outputs and extended communication protocols (e.g., DNP3) for utility applications .
- GE PQMII-T20-CA: High-precision model with advanced FFT analysis for research laboratories or semiconductor manufacturing .
- GE Multilin MMX2: A successor model offering higher sampling rates (up to 8,192 samples/cycle) and expanded harmonic analysis (up to 255th order) .
