Earthing Design Using Finite Element Method

in this project presented new method to design an earthing systems using Finite Element Method (FEM)Earthing is the art of making a connection to earth in order to protect the power system’s equipments and the personnel who work in it from the danger of electrical shocks A new method to design an earthing systems using Finite Element Method (FEM) is presented in this project. The earthing system is considered to be a rod electrode buried vertically in the ground. The resistance of the system which is a very important factor in the design process is calculated using Finite Element Method. Finite Element Method is used to estimate the solution of the partial differential equation that governs the system behavior. COMSOL Multiphysics which is one of the packages that work with the FEM is used as a tool in this design. Finally the values of the resistance obtained by COMSOL Multiphysics are compared with the proven analytical formula values for the ground resistance, in order to prove the work done with COMSOL Multiphysics
