Description
Genuine GE Hydran M2 | Professional Online Dissolved Gas & Moisture Monitoring for Oil-Immersed Transformers | Reliable Fault Early Warning | Easy Installation & Integration
Transformers are critical and high-value components of electrical grids and industrial power systems, and real-time grasp of their health status is the key to ensuring a stable and reliable power supply. The General Electric (GE) HYDRAN M2 is a compact, permanently installed online monitoring device specifically designed for oil-immersed transformers, integrating advanced sensing technology and intelligent analysis capabilities to provide a full-cycle “real-time monitoring – fault early warning – health diagnosis” solution for your power assets.
With continuous monitoring of dissolved fault gases and moisture in transformer oil, it alerts maintenance personnel to incipient fault conditions in a timely manner, helping you shift from reactive maintenance to predictive maintenance, minimize the risk of unplanned outages, and extend the service life of transformers significantly. As the third generation of GE’s proven Hydran series, it has a large global installed base, delivering trusted performance for power utilities and industrial plants worldwide.

✨ Key Features & Highlights
- Dual Sensor Options: Flexible selection between composite gas sensor and hydrogen-only sensor. The composite gas sensor responds 100% to hydrogen (a general fault gas) and is sensitive to carbon monoxide (indicating overheated paper insulation), acetylene (arcing), and ethylene (oil overheating); the hydrogen-only sensor provides focused and efficient fault monitoring for specific needs[6].
- Multi-Parameter Real-Time Monitoring: Continuously tracks dissolved fault gases (H₂, CO, C₂H₂, C₂H₄, CH₄) and moisture in oil (displayed in %RH and ppm), capturing subtle changes in transformer insulation status to identify potential issues before they develop into critical failures. It also supports additional sensors (e.g., top/bottom tank oil temperature, transformer load) for more in-depth condition analysis[6].
- Intelligent Data Analysis: Built-in mathematical models based on IEEE and IEC standards (for mineral oil) convert raw monitoring data into actionable health insights, enabling in-depth analysis of transformer conditions without complex manual calculation. It also supports lower flammability ester-based oils, adapting to diverse insulation oil types[6].
- Flexible Communication & Integration: Equipped with standard RS485 output and optional TCP/IP (copper or fibre) connectivity, supporting protocols such as IEC 60870-5-104, Modbus TCP, and DNP3 for seamless integration with SCADA or DCS systems. A PC-based configuration utility (Hydran M2 Host) is available for device commissioning and alarm management[7].
- Easy & Convenient Installation: Mounts directly on transformer valves with 1.5 inch (38mm) NPT male threads, requiring no moving parts, pumps, or extra piping. Installation is straightforward—simply wrap PTFE tape on the threads and secure with an adjustable wrench, with clear guidelines provided in the installation manual[6][9].
- Robust & Low-Maintenance Design: Features a vacuum-resistant gas extraction membrane and built-in temperature conditioning system, with full self-test and self-diagnostic functions to ensure continuous operation. No on-site calibration is required, and it stores up to 12 months of data and significant events for historical trend analysis.
- Configurable Alarm System: Two levels of alarms (alert and critical) can be set to notify personnel of abnormal fault gas or moisture levels, with both local and remote alarm capabilities to ensure timely response to potential issues[6].
