Product Overview
Transformers are key and expensive components of the electrical grid and 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.
The Hydran 201Ti is a small and easy to setup continuous 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.
