GE PQMII-T20-C-A Power Quality Meter

Technical Specifications 

The PQMII-T20-C-A is a GE Vernova Multilin power quality meter for continuous monitoring of single- and three-phase electrical systems. It measures current, voltage, real and reactive power, energy, power factor, frequency, and demand. This configuration includes the T20 transducer option with four isolated 4–20 mA outputs, one 4–20 mA input, and a second RS485 port. The C option adds three programmable output relays and four switch inputs. The A power analysis option adds harmonic analysis, waveform capture, event recording, data logging, and voltage disturbance recording. Current and voltage metering accuracy is 0.2%.

Key Features & Capabilities

This power quality meter integrates seamlessly with industrial monitoring systems, offering extensive measurement capabilities including voltage/current RMS values, active/reactive/apparent power, power factor, frequency, total harmonic distortion (THD), and individual harmonic analysis up to the 63rd order. The T20 transducer configuration enables monitoring of auxiliary parameters such as temperature, pressure, or flow when paired with appropriate sensors.Advanced waveform capture functionality records voltage sags, swells, and transients with precise time-stamping, enabling detailed post-event analysis. The meter's onboard memory stores up to 512 events with associated waveforms, providing comprehensive historical data for troubleshooting and compliance reporting.

Application Scenarios

Industrial Manufacturing: Monitor power quality at critical production lines to prevent equipment damage and production downtime. The PQMII-T20-C-A identifies voltage disturbances before they impact sensitive machinery, similar to protection offered by the GE SR469 Multilin Motor Protection Relay for motor-driven systems.
Data Centers: Ensure clean, stable power delivery to IT infrastructure. Pair with the GE EPM 9650Q Power Quality Meter for multi-point monitoring across facility distribution systems.
Renewable Energy: Track power quality at solar inverter and wind turbine outputs. Integrate with GE 489-P5-HI-A20-E-H Generator Management Relay for comprehensive generator protection and monitoring.
