The HYDROCAL 1010-3 is designed formulti-gas-in-oil analysis
on a bank of three single phase transformers located next to each
other. This new wall mounted system allows for the individual
measurement of Moisture in Oil (H2O) and the key gases Hydrogen
(H2), Carbon Monoxide (CO), Carbon Dioxide (CO2), Methane
(CH4), Acetylene (C2H2), Ethylene (C2H4), Ethane (C2H6), Oxygen (O2) and Nitrogen (N2)d i s solved in transformer oil utilizing a sampling system that samples oil from each tank via three separate oil channels expertly engineered to provide negligible mixing of oil.
As Hydrogen (H2) is involved in nearly every fault of the insulation
system of power transformers and Carbon Monoxide (CO) is a signof an involvement of the cellulosic / paper insulation the presenceand increase of Acetylene (C2H2) and Ethylene (C2H4) further clas-sifies the nature of a fault as overheating, partial discharge or highenergy arcing. Oxygen (O2) can be a sign of excessive ageing or leakages
within the sealing of hermetic transformers.
