The Hydran M2 is a compact permanently mounted on-line transformer monitoring device that will alert personnel to developing fault conditions. It continuously monitors a composite value of various fault gases (in ppm) or a Hydrogen gas only value (depending on sensor purchased). In addition it tracks moisture in oil (reading in %RH and ppm).

With additional sensors added, the Hydran M2 can also compute transformer mathematical models based on IEEE® and IEC® standards to provide further information on the performance of the transformer.

Benefits
• Real-time Hydrogen or composite fault gas monitoring system
• Moisture in oil measurement
• Ability to integrate additional sensors (load, oil temperature, …)
• Option to process transformer mathematical models based on IEC/IEEE standards
• Easy to install on a single valve.
• No moving parts, no pumps and no extra piping required.
• No field calibration required.
• Local and remote alarms set at pre defined levels.

Features
• Hydrogen sensor responds 100% to Hydrogen (general fault gas)
• Composite gas sensor responds 100% to Hydrogen and is also sensitive to Carbon Dioxide (overheated paper insulation).
• Choice of up to 4x input or output cards
• Wide range of communication methods and protocols.
• RS485 output is standard. TCP/IP copper or fibre is optional
• Vacuum-resistant gas extraction membrane.
• Built in temperature condition system.
• Full system self test and self-diagnostics.
• Logging of data and significant events up to a year.
• User-friendly client/server graphical user interface software.

Applications
• Medium to large sized transformers.
• Lower risk and/or consequence of failure.
