The main purpose of this article is to study the optimum design of grounding system of high voltage substations by using artificial neural network. The proposed study will implement the following important contributions: 1Performance of grounding system under uniform and nonuniform soil resistivity. 2Grounding by using equal and nonequal spacing grids studying the performance of non equal spacing grid incase of uniform and nonuniform soil. 3Grounding by grids and rods in non uniform soil and unequally spaced grids. 4Safety analysis of grounding grid with different structures. 5Designing of ANN as a tool to select the optimum grounding system. 6Performance of grounding system under transient conditions.
