Protection of equipment insulation against lightning over voltages and selection of lightning arrester for 220 kV substations that will discharge at lower voltage level than the voltage required to breakdown the electrical equipment insulation is examined. The objectives of this paper is to select appropriate lightning arrester with the lowest rated surge arrester that will provide adequate protection of equipment insulation and equally have a satisfactory service life when connected to a specified line voltage in power system network. The effectiveness and non-effectiveness of earthing system of substation determines arrester properties. Also Standards recognize that particular attention is required for the earthing of surge arresters. A MATLAB program is used in the development of model for the determination of Surge arrester grounding grid parameters like calculation of tolerable limits of current to the body, typical shock situations, tolerable touch and step voltages, maximum fault current, grid resistance, grid current, ground potential rise.
