  • Dissolved gas analysis - Wikipedia

    Dissolved gas analysis is an examination of electrical transformer oil contaminants. Insulating materials within electrical equipment liberate gases as they slowly break down over time. The composition and distribution of these dissolved gases are indicators of the effects of deterioration, such as pyrolysis or partial discharge, and the rate of gas generation indicates the severity. DGA is beneficial to a preventive maintenance program. The collection and analysis of gases in an oil-insulated t

  • Dissolved Gas Analysis in Transformer Oil

    Dissolved Gas Analysis in Transformer Oil. 1. In substation, Transformer is the most efficient and costly equipment. So in order to protect from faults, Transformer oil testing is required. The transformer’s fluid not only serves as a heat transfer medium, it also a part of transformer’s insulation system. It is therefore prudent to periodically perform tests on the oil to determine whether it is capable of fulfilling its role as an insulant.

  • Significance of CO2/CO ratio in dissolved gas analysis

    AbstractIntroductionCarbon Monoxide and Carbon Dioxide in Transformer OilCase 1According to the literature, the ratio of carbon dioxide and carbon monoxide (CO2/CO) for a transformer with a healthy cellulose insulation system should be between 3 and 11. If results of the dissolved gas analysis (DGA) of oil from transformers in service give the ratio value of CO2/CO less than 3, it means that the cellulose insulation is degrading rapidly. What is the meaning of this ratio if it is high; say greater than 15 or 20? Keywords:carbon monoxide, carbon dioxide, ratio, dissolved gas analysis
