The Hydran M2-X is the next generation of the field-proven family of Hydran DGA monitoring solutions,

providing continuous monitoring of gas and moisture levels to alert users of developing faults and minimize the

risk of unplanned outages. The M2-X builds on GE’s strong domain expertise to deliver an optimized, low maintenance monitoring device with extended sensor life.

The Hydran M2-X is also available in a UL certified, HazLoc version (part number: M2-X-HZ) for installation

on transformers located in hazardous locations designated as Class I, Division 2

The Hydran sensors are available as a traditional Hydran composite gas (H₂, CO, C₂H₂, C₂H₄) sensor or a

discrete Hydrogen only (H₂) sensor. In addition, it tracks moisture in oil (reading in %RH and ppm) and is

compatible with various transformer oil types (standard mineral insulating oils and newer natural and synthetic ester based fluids).

HYDRAN M2-X

Key Benefits

• Small form factor, no moving parts, and low maintenance
• Support for Asset Performance Management (APM) software analytics, enabling fleet level deployments
• Condition monitoring for transformers with mineral insulating oils or ester based fluids (natural and synthetic)
• Extending beyond DGA monitoring, through the connection of sensors, the Hydran M2-X can
• monitor other parameters such as top oil temperature, load current and through the use of IEEE based
• mathematical models, can provide further insight on changing transformer conditions
• Provides critical data for APM strategies, facilitating planning of site intervention and maintenance activities
• The M2-X-HZ version is certified for hazardous locations where ignitable concentrations of flammable
• gases, vapors or liquids are not likely to exist under normal operating conditions but where the risk still exists.

Features

• Easily upgradeable in the field to accept analog signals and monitor other key transformer parameters
• Computation of winding hot spot and other IEEE transformer models for enhanced diagnostics
• of the transformer’s condition (depending on sensors installed)
• Easy to install on a single existing transformer valve, often without an outage required
• Integrated display and keypad for simplified local user interaction and data visualization
• Built-in moisture sensor provides water in oil measurement, critical to identify paper degradation and leaking gaskets
• Compatible with GE’s acclaimed Perception™ software to download, trend and analyse transformer health data
