The transformer winding deformation tester is used to test the transformer winding deformation of 6kV and above power transformers and other special-purpose transformers. Power transformers are inevitably subjected to various fault short-circuit currents or physical shocks during operation or transportation. Under the strong electromotive force generated by the short-circuit currents, the transformer windings may lose stability, causing local distortion, bulging or displacement. Such deformation phenomenon will seriously affect the safe operation of the transformer. According to the national power industry standard DL/T911-2016, the frequency response analysis method is used to measure the winding deformation of the transformer. It is by detecting the amplitude-frequency response characteristics of each winding of the transformer, and comparing the test results longitudinally or laterally, according to the change of the amplitude-frequency response characteristics To determine the possible deformation of the transformer winding.

* The frequency sweep method is used to measure the winding characteristics of the transformer. Without hanging the cover and disassembling the transformer, by detecting the amplitude-frequency response characteristics of each winding, for transformers of 6kV and above, accurately measure the winding twist, bulge or displacement, etc. Deformation.
