| Abstract: | An overheat fault of 220 kV transformer is analyzed. Firstly,the type of the transformer fault is determined by oil chromatography analysis. Then,the internal components of the transformer tank are checked one by one. Finally,the fault cause is diagnosed as the circulation problem of the components,which causes the transformer with too high local temperature. |
