Hydran M2

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.
 
  • Transmission transformers.
  • Significant step up from manual oil sampling.
