Electric Field Calculations by Numerical Techniques

Abstract

Objective of the study of electric field calculations by numerical techniques is to use different numerical techniques to find electric field distributions, which are inevitable tool in various electricity-concerned technologies, in particular, for analyzing discharge phenomenon and designing high voltage equipment. In this thesis, two numerical methods are discussed; e.g. finite difference method and finite element method. Both methods are used to find two dimensional electric field distributions with given boundary conditions using MATLAB. Electric field distributions in more practical three dimensional cases with non-uniformly distributed dielectric of a capacitor and in a DC busbar has found using C-programming. Also, electromagnetic field calculations of electric motor have been done in ANSYS.
