Abstract The diagnosis of transformer winding deformation using frequency response analysis is based on the comparison of curves. The variation of frequency response curves corresponds to the types of winding deformation needs to refine and sum up, combed with the concrete case. In this paper, the winding deformation frequency-response curve of an 110kV power transformer is analyzed based on frequency response analysis. Combined with the correlation coefficient, the situation of main transformer winding deformation is analyzed and judged. With disassembling inspection, the frequency division of the frequency response curve are comprehensive analyzed and summarized.
