Description
Product Overview
The GE HYDRAN M2 is a compact, permanently installed online dissolved gas-in-oil (DGA) monitoring system designed for real-time analysis of transformer health. As part of GE’s globally recognized HYDRAN series, this advanced device continuously monitors dissolved hydrogen (H₂), carbon monoxide (CO), acetylene (C₂H₂), ethylene (C₂H₄), and moisture in transformer oil, providing early warnings of insulation degradation, arcing, or overheating 612. Engineered with a NEMA 4X-rated enclosure and a vacuum-resistant gas extraction membrane, the GE HYDRAN M2 withstands extreme temperatures (-40°C to +85°C) and harsh environments, ensuring reliable performance in utility-scale power plants, offshore platforms, and industrial facilities 1012.

Featuring a composite gas sensor (100% response to hydrogen) or optional discrete hydrogen-only sensor, the GE HYDRAN M2 delivers ppm-level accuracy for fault gas detection, aligning with IEEE C57.104 and IEC 60599 standards 1112. Its built-in moisture sensor tracks water-in-oil content (0–100% RH/ppm), critical for identifying paper degradation and gasket leaks 612. With support for Modbus RTU, DNP3, and Ethernet communication, the system integrates seamlessly with SCADA systems, GE’s Perception™ software, and cloud platforms for centralized data analysis and predictive maintenance 17.
The GE HYDRAN M2 also supports IEEE-based mathematical models to compute winding hot-spot temperature, insulation aging, and apparent power, enhancing diagnostic capabilities. Its no-moving-parts design and self-diagnostics reduce maintenance needs, while local alarms and a backlit LCD display enable real-time status monitoring 617.

Main Features and Advantages
Comprehensive Fault Detection: The GE HYDRAN M2 combines DGA with moisture monitoring to detect multiple failure modes, including overheated insulation, partial discharges, and gasket leaks. Its composite gas sensor covers all major fault gases, while the hydrogen-only sensor provides targeted early warning of general faults 1217.
Advanced Analytics: Built-in IEEE-based mathematical models compute critical parameters like winding hot-spot temperature and insulation aging, converting raw sensor data into actionable insights. This enables predictive maintenance and extends transformer lifespan 617.
Rugged Design: With a NEMA 4X enclosure and conformal-coated circuitry, the GE HYDRAN M2 operates reliably in extreme temperatures, humidity, and corrosive environments. Its no-moving-parts design eliminates pumps or filters, reducing maintenance costs by up to 50% compared to traditional systems 612.
Flexible Integration: The system supports Modbus, DNP3, and Ethernet, enabling seamless integration with SCADA, DCS, and cloud platforms. It also connects to GE’s Perception™ software for trend analysis and remote diagnostics 17.
User-Friendly Interface: A backlit LCD display and front-panel keypad allow local configuration of alarm thresholds (high/high-high) and real-time data visualization. Remote access via RS-485 or Ethernet simplifies fleet management 617.
