| Abstract: | Employing frequency-response analysis method to test transformer winding's distortion will meet some influence from many factors,which will make the test result distort and will bring difficulties to analyze the result.All influence factors and infecting degree are analyzed here with the typical spot test example,and it indicates the frequency-response's validity in the transformer winding's distortion after eliminating the infecting factors. |
