Abstract
The purpose of this study is to clarify the characteristic of vibration of the transformer coil, and to predict electromagnetism vibration of the transformer coil. Therefore, the exact Finite Element Method (FEM) model of transformer coil is required. In this research, the modeling of the transformer coil vibration of the axis direction and the diameter direction was carried out. The modeling of the transformer coil was performed with the equivalent parameter. The equivalent parameter calculated based on the Experimental Modal Analysis (EMA) result. The characteristic value analysis error is 10% or less. The result of the frequency response analysis of the FEM model was good agreement with the experimental result.
