Enhanced Monitoring with Extended Sensor Life

​

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).

​

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 upgradable 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

 

Applications

​

• Medium to large sized transformers

• Utility and industrial transformers

• Transmission transformers
