The electric field distribution in medium voltage roof top bushing is principally dependent on the geometry dimension and types of the materials used. The main target is to achieve a bushing design which has a good field stress control. Various combinations of conductive, insulated and earthed parts, connected with the bushing have been treated in the development phase. In this paper, two-dimensional (2D) axial-symmetrical model geometries of roof top bushing have been developed using finite element analysis (FEA) method, which is ANSYS MAXWELL software. These models have been used to obtain the electric filed distribution in roof top bushing model. The effect of the bushing permittivity, electrical conductivity, the width, length and the metallic interface on the electric field distribution in roof bushing structure were analysed. From this study, an understanding of electric field distribution in roof top bushing geometry may be attained, which may help in designing of medium voltage roof top bushing stress control. With the help of simulation result proposed the new design of roof top bushing and it is verified by different test.
