GE Grid Solutions Hydran M2-X Brief Product Description

GE 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 Vernova’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 Vernova’s digital platforms including Perception™
transformer fleet management software, 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.
