Electric Field and Voltage Distribution (EFVD) Analysis for 132kV Bushing Transformer Using Finite Element Analysis

Abstract

The electric field and voltage distribution (EFVD) are an important parameter for assessing high voltage bushing transformer performance. In order to understand how EFVD being distributed along the bushing transformer, Finite Element Method (FEM) has been employed for simulation purposed. 2 dimensional (2D) object designed using Computer Aided Design (CAD) using actual dimension of 145kV bushing transformer from manufacturer data sheet. The model is then exported to Finite Element Method (FEM) software for further analysis. Using FEM, the EFVD can be obtained. From this study, an understanding of electric field and voltage distribution along bushing transformer and between aluminium foils are attained.
