Winding deformation detection plays an important role in the prevention of short circuit damage of transformer. Based on the detailed analysis of test principle, test method, and judging criterion of the frequency response method, impedance method, and capacitance method, and combined with theoretical analysis and field measurement, the balance winding, connection mode, test process, environmental interference, and other infulencing factors were analyzed deeply. Then the auxiliary function of conventional test methods such as oil chromatogram, PD, DC resistance in the analysis of transformer winding deformation was studied, and the relationship among the transformer winding deformation, the ability of anti short circuit and short circuit impact was analyzed. Finally, according the relativity and complementarity of various kinds of winding deformation test methods, the test and diagnosis method of winding deformation based on multiple methods was proposed.
