GE HYDRAN M2 Transformer monitoring equipment

When a transformer’s insulation system is overstressed, the oil and paper undergo chemical
degradation producing both hydro-carbon gases and moisture that dissolve into the insulating oil. This
increased ageing will shorten the transformer’s life, impact its reliability and in some cases can even
lead to catastrophic failures.
The Hydran M2-X is the next generation of the field-proven family of Hydran DGA monitoring solutions.
It provides 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 an extended sensor life.
Key Benefits
• Small form factor, no moving parts, low maintenance, and support for APM software analytics,
enabling fleet level deployments
• Condition monitoring for a wide range of 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
• Providing critical transformer gas behavior data for Asset Performance Management (APM)
strategies, facilitating planning of site intervention and maintenance activities
• Supports a wide range of communication methods and protocols to enable easy and secure
integration with GE’s digital platforms including Perception™ transformer fleet management
software, DS Agile substation HMI, PREDIX™, and other APM software tools, historians and SCADA
systems
Applications
