Hydran 201Ti
The Hydran 201Ti is a small on-line early warning transmitter. It is permanently mounted on the transformer and will provide personnel with a single reading in ppm of a composite value of various fault gases to alert them to a potential issue.

This value can be downloaded and alarms can be set at pre-determined levels to alert personnel and enable monitoring of the developing fault condition.
  • Small and medium sized transformers.
  • Lower risk and/or consequence of failure.
  • Ideal for Transmission transformers.
  • Much better than relying on manual oil sampling.

  • Real-time single composite fault-gas measurement system.
  • Local and remote alarms set at pre defined levels or on rate of change.
  • Remote visibility of the gas reading and trend via serial port communication.
  • Easy to install on a single valve.
  • No moving parts, no pumps and no extra piping required.
  • No field calibration required.
  • Composite gas sensor which responds 100%
    to Hydrogen(general fault gas) and is sensitive
    to Carbon Dioxide (overheated paper insulation).
  • LCD display.
  • RS-485 connection as standard.
  • Modbus or Hydran protocols available.
  • Vacuum-resistant gas extraction membrane.
  • Full system self test and self-diagnostics.
  • User-friendly client/server graphical user interface software (GUI).
  • Local logging of data and significant events for up to a year.
