GE PQMII-T20-C Power Quality Meter – Product Description

The GE Multilin PQMII-T20-C meter provides accurate and dependable monitoring for three-phase electrical systems in industrial and utility environments. It offers real-time analysis of voltage, current, and power quality metrics, helping operators understand system behavior and respond quickly to disturbances. Moreover, the device supports advanced protection features that reduce downtime and improve equipment reliability across demanding power networks.

This model balances measurement depth with practical control capabilities, enabling users to automate alarms, manage loads, or support capacitor bank switching. In addition, its combination of analog outputs, switch inputs, and programmable relays allows engineers to configure custom logic without external hardware. The large backlit LCD display improves day-to-day usability, while the communication ports integrate smoothly with SCADA platforms and modern automation systems.

Its rugged construction withstands industrial environments, and the optional conformal coating enhances durability in corrosive or dusty locations. For instance, the PQMII-T20-C maintains stable performance in pulp mills, chemical plants, and data centers where power quality directly affects operational safety.
