The Analysis and Treatment of an Abnormal Test Result of 220 kV Transformer

The abnormal chromatogram and DC resistance of 220 kV transformer is analyzed. The result shows that the abnormal DC resistance is caused by unequal internal connection lines and the abnormal chromatogram is due to fault of oil pump. It is determined that there is no any fault in the transformer itself.
