In recent years, since 25-30 years operating oil immersed transformers have been increasing in number, development of life diagnosis method in the transformer is carried out actively.
We find that the insulating paper has property which absorbs CO2 and CO in oil.
In this study, absorption phenomena of CO2 and CO in the insulating paper are investigated to get good accuracy life diagnosis. Results are as follows.
(1) These phenomena are also confirmed in the actual transformers.
(2) Content of CO2 and CO in oil decreases with decreasing temperature.
(3) Property of absorption in the insulating paper disappears above 80°C.
