GE H201TI 变压器基本DGA监测

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 firstline of defence for the transformers in your fleet to obtain advance warning of a failure condition andminimize the risk of unplanned outages.

The 201Ti’s composite-gas sensor provides the world renown “Hydran gas value” using fuel celltechnology (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) andEthylene (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 noneed for a pump or extra piping to connect to different valves.  Due to its uncomplicated features andthe easily understood information it provides, the 201Ti has been amongst the monitors of choice formany 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 newelectronic boards and power supply to make it RoHS compliant, address any obsolescence issue andfurther 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
