| Abstract: | Base on the fatigue mechanism of transformer, the essay introduces Condition Based Risk Management (CBRM) methodology and puts an emphasis on the discussion of how to assess the condition of transformer using the analysis data of oil and the mixture gas of oil, and the caculation of indexs, including health index, probability of failure and end of life, which could directly reflect the overall condition of power transformer. Conduct a assessment of power transformer using the way in the essay for GuangZhou Power Supply Bureau, the output proves that the methodology in this essay could assess the condition of power transformer precisely. |
