Method for testing deformation of transformer winding

The invention discloses a transformer winding deformation test method, which comprises the following steps: S1, applying a signal to each winding of a transformer, measuring response signals at two ends of each winding, and extracting reflected waves of the response signals; and S2, comparing the waveforms of the reflected waves of the three-phase windings, and if the reflected waves of one winding are different from the reflected waves of the other two windings, determining that the winding is deformed. According to the invention, the deformation of the winding of the transformer can be accurately judged through less sampling data, the tester emits high-frequency sinusoidal signals, the influence of interference signals can be conveniently eliminated, the anti-interference capability is strong, the repeatability of a measurement result can be easily ensured, and the method has the advantages of high detection sensitivity, convenience in field use and the like. 本发明公开了一种变压器绕组变形的测试方法，该方法包括：S1、对所述变压器的每一绕组施加信号，测量
