GE Grid Solutions Hydran M2-X

Proven Technology

• Field proven solution, delivering online DGA

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

• Easily upgradable in the field to accept

analogue signals to 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)

• 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
