Overview
The transformer winding deformation tester quantifies the response changes of the internal winding parameters of the transformer in different frequency domains, and determines the degree of change in the internal winding of the transformer based on the magnitude of the change, the amplitude and region of the frequency response change, and the trend of the frequency response change. Therefore, the measurement results can be used to determine whether the transformer has been severely damaged and whether major repairs are needed.
