“…[12]The FEA procedure is done in a highly sequential manner which stands to be successful. It consists of formulation of the problem in variation form, discretization [10] of the formulation using [mite element thereby obtaining solution in the form of equation. These are the fundamental steps for any problem, which also includes use of digital equipments for further analysis of engineering problem.…”

Transformer bushings are one of the important components in the construction of high voltage power transmission. The structure and materials used in electrical bushings play a vital role in the durability and lifespan of the bushing. Although the cost of transformer bushing is very minimal in the transmission system extensive damages are caused in case of failure. The main reason of failure in the insulation materials are caused due to moisture ingress and formation of voids, cavities. When the appropriate material is used along with an optimized structure, the electric field is distributed evenly which reduces the stress and increases the longevity of the bushing. In this paper, Finite Element Analysis(FEA) is used to calculate The ELECTRIC FIELD DISTRIBUTION and THERMAL(Temperature) Analysis is done for 765kV transformer bushing by using different insulating materials such as Epoxy Resin, Porcelain, Oil Impregnated Paper, Resin Impregnated Paper and Polymer.Henceforth, by using the above insulating materials the total stress level of the bushings corresponding to the net electric field distribution is in turn calculated using ANSYS 13.0Software. The results are compared and analysis is done for the different insulating materials. Based on the electric field distribution over bushing material, it is used to identify optimization of bushing design.

“…Converter transformer bushing is the key equipment to connect the converter transformer and the converter valve. It carries full voltage, current, and strong mechanical load during long‐term operation, thus its safe operation is critical to the stability and reliability of the power system [1]. Before putting bushing into operation, the routine test should be conducted to ensure its electrical, thermal and mechanical properties stipulated in IEC 62199 [2] and IEC 60137 [3] to meet the operational requirements.…”
