Abstract
Winding vibration is one of the most important noise sources in loaded power transformers. However, accurate and effective modelling of the winding vibration response is often hindered by the complicated conductor and insulation material distributions in the winding structure. In this paper, the winding is described by a coupled-ring model, which are applied on three experimental winding structures. The vibration response of the winding to a point force excitation is then analysed using the finite element method. This simplified model allows efficient prediction and understanding of the vibration characteristics of complex winding structures.
