Hydrogen gas transmitter Hydran 201Ti

Real Time Radiographyin-lineModbus

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. Applications •Small and medium sized transformers. •Lower risk and/or consequence of failure. •Ideal for Transmission transformers. •Much better than relying on manual oil sampling. Benefits •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. Features •Composite gas sensor which responds 100% to Hydrogen (general fault gas) and is sensitive to Carbon Dioxide (overheated paper). •LCD display. •RS-485 connection as standard. •Modbus or Hydran protocols available. •Vacuum-resistant gas extraction membrane. •Full system self test and self-diagnostics. •Local logging of data and significant events for up to a year.
