The GE Hydran 201Ti is a continuous dissolved gas in oil analysis (DGA) monitor designed to provide early warning of transformer failure conditions, thereby minimising unplanned outages [0]. The Hydran 201Ti is permanently installed on the transformer and provides workers with a single reading (ppm) of various faulty gas complex values to alert them to potential problems [1]. The value can be downloaded and alerts can be set at a pre-determined level to alert people and be able to monitor developing failure conditions.
The Hydran 201Ti features local and remote alarms, set at predefined levels or rates of change, and remotely view gas readings and trends via serial port communication. The device has a composite gas sensor that is 100% responsive to hydrogen (a general fault gas) and sensitive to carbon dioxide (overheated paper)
The Hydran 201Ti includes a standard Hydran sensor, a thermal regulation system, and a microprocessor-based transmitter. Terminals are easy to connect to AC power, alarm points (high gas, high gas, and system failures), adjust connections, and simulate 0-1mA non-isolated outputs. 4-20mA isolated outputs can also be purchased. It also provides a computer interface
