solutions for over 40 years
• Over 50,000 Hydran units sold worldwide
• Estimated sensor life in excess of 10 years*
Expandable
• Compatible with various transformer oil types
(standard mineral insulating oils and newer
natural and synthetic ester based fluids)
• Available with the traditional Hydran
composite gas (H2, CO, C₂H₂, C₂H₄) sensor or
with a discrete Hydrogen only (H2) sensor

IEEE transformer models for enhanced
diagnostics of the transformer’s condition
(depending on sensors installed)
• Integrates with Kelman multi-gas DGA devices
Intuitive
• 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 identifying paper
degradation and leaking gaskets
• Compatible with GE’s acclaimed Perception™
software to download, trend and analyze
transformer health data
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
