GE Grid Solutions Hydran M2-X

Enhanced Monitoring with Extended Sensor Life

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

Advanced, flexible and expandable DGA monitoring solution tailored for utility and industrial

transformers.

Easily integrates with Kelman multi-gas DGA devices and the Multilin 845 protection & control

relay to provide continuous synchronization of chemical and electrical measurements for enhanced

transformer monitoring
