  • Degradation of power transformer insulation materials

    Jun 15, 2020 · Internal faults in the transformer usually develop by decomposition of the insulating oils which in turn produces gases such as hydrogen, methane acetylene, ethane, ethylene. The degradation of cellulose paper produces methane, hydrogen, carbon monoxide and carbon dioxide. Carbon monoxide and carbon dioxide reveal paper degradation related faults.

  • Significance of CO2/CO ratio in - Transformers Magazine

    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
