“…Four classical methods for solving the partial differential equations (PDE) are the charge simulation method (CSM), the finite difference method (FDM), the boundary element method (BEM) [9] and the finite element method (FEM) [10][11][12]. Out of these four, FEM has a dominant position because of its strong interchangeability [13][14][15].…”

High voltage insulators are mainly used to support transmission lines. This paper focuses on simulating the electric field along the surface of contaminated Silicone Rubber (SIR) insulators. The electric field (EF) distribution is important to determine the EF stress occurring on the insulator surface. So, the EF distribution is analyzed using a FEM tool in MATLAB under various conditions. Two types of insulators, straight and alternate sheds, were considered. Results showed that higher EF stresses occurs on the trunk portions of both straight shed and alternate shed types. Also, the results showed higher EF magnitude on the straight shed compared to the alternate shed, under both clean and contamination conditions.

In this paper support vector machine (SVM) has been used for optimization of electric field along the support insulators used in high voltage (HV) systems. To illustrate the effectiveness of SVM in optimizing electric field problems, two axi-symmetric cases have been considered one having an insulator with a contour that is quarter ellipse and the second one having a porcelain core solid insulator. The training and the test data for the SVM have been prepared by electrostatic field computation using indirect boundary element method (BEM). It is observed that once the SVM is trained it is able to give results with mean absolute error of less than 1.5 % when compared with the analytically obtained results. The SVM designed for insulator contour optimization is first trained with the results obtained from electric field computation for some predetermined contours of the arrangements under consideration. Then the trained SVM is used to produce an optimized insulator contour in such a way that the desired stress distribution can be obtained on the insulator surface. The results obtained from the present study show that the trained SVM is adequately efficient to optimize insulator contours in order to have the desired stress distribution along the insulator surface. He has published several research papers both at international and national levels. His current areas of research are numerical computation of electrostatic field, computer-aided design and optimization of high voltage systems by using soft-computing techniques.

Capacitive-resistive field distributions including surface and volume resistivities have been computed in and around HV porcelain and capacitor bushings. The boundary element method has been applied for field computation in two axi-symmetric bushing configurations including four dielectrics. Effects of uniform and non-uniform distributions of surface resistivity and volume resistivities of different dielectric media are studied in detail. Special emphasis has been given to the stress distributions along the various dielectric-dielectric boundaries. Further, the values and locations of maximum stresses in different dielectrics are determined and reported in this paper. The plots of equipotential lines for a few typical cases of field distributions are also presented here for both bushings.
