Transformer wingding can be equal to a mechanical structure

if the structure is changed

its modal will be changed. Vibration signal frequency response analysis is carried out. So it can detect the winding deformation So it is significant to analyze the winding modal. In order to make the modal analysis for the winding

the winding picture change model is established with ANSYS

and the result shows the trend of vibration frequency curve with the comparing the normal winding and deformation winding. Experiment of real transformer is carried out

the simulation result is verified correct by comparing with experimental result

and it lay a foundation for research and fabrication of vibration detecting system.
