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 trended 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.

Distribution and Transmission transformers.
First step up from manual oil sampling.


Real-time single composite fault-gas and moisture in-oil measurement system. Local and remote alarms set at pre defined levels. Option to add a seperate controller to allow remote visibility of the gas reading and transmit the value via a serial port.		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. RS232/258 connection as standard. Local logging of data and significant events for up to a year.		Vacuum-resistant gas extraction membrane. Built in temperature condition system. Full system self test and self-diagnostics. User-friendly client/server graphical user interface software (GUI).
