The GE Multilin PQM II monitors and controls electrical power systems. It is ideal for large-scale installations like substations and industrial facilities.

Key Features and Capabilities

• Comprehensive Power Quality Monitoring: Measures voltage, current, power (various types), energy consumption, power factor, and frequency.
• Control Functions: Allows customizable control actions based on measured values, such as load shedding, power factor correction, and alarms.
• Communication Flexibility: Offers multiple communication ports (RS-485, RS-232) to integrate with other systems.
• Harmonic Analysis: Identifies and analyzes harmonic distortions in the power system to prevent equipment damage.
• Data Logging and Analysis: Records data for later analysis to troubleshoot power quality issues.
