GE HYDRAN 201Ti | Mark IV | ONE Channel Controller Gas analyzer.It is Essential DGA monitoring for transformers，knowledge of their health condition is essential to having a reliable network. When a transformer’s insulation system is overstressed, gases are produced that dissolve in the oil. Dissolved Gas-in-oil Analysis (DGA) is recognized as the best indicator of developing faults.（Click for related products:HYDRANM2-X Hydran M2-X、Hydran M2 Mark III 、HYDRAN H201Ci-1）
The Hydran™ 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 an unplanned outage.
The 201Ti uses fuel cell technology (described as fixed instruments - method 3 in the standard) and is
now available with a choice of either the world renown “Hydran Composite Gas” sensor which responds
100% to Hydrogen and is also sensitive to Carbon Monoxide, Acetylene and Ethylene or the more basic
“Hydrogen Only” sensor which focuses purely on Hydrogen gas generation.
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 DGA monitor.
Key Benefits
• Continually measures key fault gas to give you an insight into the transformer’s condition
• Choice of gas sensor: traditional “Composite gas” or more basic “Hydrogen only”
• Communicates gas ppm and gas rate of change values remotely to avoid site visits and enable
remote supervision
• Fourth generation of this continuously improved design, with over 25,000 units sold worldwide.
