GE Digital Energy Hydran 201Ti Transformer DGA Monitor
The HydranTM 201Ti is a small and easy to setup continuous Dissolved Gas-in-oil Analysis (DGA) monitor.
It provides the basic information used by IEEE® Standard C57.104 and can be used as an essential first line of defence for the transformers in your fleet to obtain advance warning of a failure condition and minimize the risk of unplanned outages.
The 201Ti’s composite-gas sensor provides the world renown “Hydran gas value” using fuel cell technology (described as fixed instruments - method 3 in the standard). It responds 100% to Hydrogen(general fault gas) and is also sensitive to Carbon Monoxide (overheated paper), Acetylene (arcing) and Ethylene (overheated oil), thus covering all the main transformer failure root causes.
Because the monitoring unit mounts on a single valve and uses Dynamic Oil Sampling, there is no need for a pump or extra piping to connect to different valves. Due to its uncomplicated features and the easily understood information it provides, the 201Ti has been amongst the monitors of choice for many years, with one of the largest installed base of any monitor.
With the latest Mark IV version, the Hydran 201Ti monitor has been completely overhauled with new electronic boards and power supply to make it RoHS compliant, address any obsolescence issue and further improve this time proven product


It now offers additional features like:

• Improved sensor
• Modbus® protocol communication over isolated RS-485
• Local USB port to replace the RS-232 port no longer found on most field laptops
• Compatibility with GE’s acclaimed PerceptionTM Fleet software to download,trend and analyse data,like with any other GE DGA monitoring equipment
Key Benefits
• Continually measures main H₂ fault gas
• Local LCD display
• Communicates gas ppm value remotely
• Proven and continuously improved design (over 30,000 units sold)

• Easy to install, single valve mount

Applications

Power Utilities
• Simple and effective solution for less-critical transformers
• Focuses and prioritizes asset replacement strategy
Industrial Plants
• Reduces the risk of process interruption due to power failure
• Minimizes costly production downtime


Easy Asset Supervision

• Permanently mounts on a single transformer oil valve. No extra piping or pump required
• Gas sensor responds 100% to Hydrogen(general fault gas) and is also sensitive to Carbon Monoxide (overheated paper)
• Optional 5 year sensor guarantee
Configurable Alarms
• An alarm is raised when an abnormal level of fault gas is detected
• Two alarm levels (one for Alert and one for Alarm) can be set to show increasing severity
• Alarms can be set on gas ppm levels or on gas rate of change (ROC) over an hour or a day
• Automatic self-test every 15 days will trigger service alarm if it detects a fault, including power failure, oil valve closed, sensor or battery needing replacement


Communication

• Local LCD display of the real-time dissolved gas ppm value
• Analogue output (4-20mA) of the dissolved gas ppm value
• Digital output of registers using Modbus or Hydran protocols over isolated RS-485
• 3 dry contact relays also available 2 for the fault gas alarms and one for the service alarm



Controllers

The 201Ti can be connected to optional controllers to facilitate communication with multiple units and create a local network.
• The Ci-1 controller is a one channel controller that replicates some of the human interface functions (gas value display, alarm buttons). This is ideal when the is mounted out of reach on an upper valve of the transformer. It also brings down the alarm relay contacts and the analogue output for easier wiring.
• The Ci-C controller receives the gas ppm data from up to four H201Ti, providing a single communication point for all four monitors. It has no alarm relay or analogue output. This is ideal when protecting 3 single phase transformers + 1 spare.It is possible to “daisy-chain” up to 32 controllers or 201Ti through their RS-485 port. The maximum chain distance (all cables added up) is 1200m (4000ft). All the 201Ti connected to any of the daisy-chained controllers can be accessed through any controller in the local network, thus facilitating communication by only having to fit one RS-232 modem for example.
