This paper demonstrates the importance of a surge arrester in the power system. It includes design of a surge arrester, calculation of lightning current and the simulation results. The intension of designing a surge arrester is to protect the substation equipment’s and to provide stability to the power system. Over voltages in the transmission line are reduced using Metal Oxide surge arresters. This paper also demonstrates the significance of having an appropriate location of surge arresters. This is done by measuring the voltage at the equipment for different locations of surge arresters. The 1.065kA, 2.662kA and 5.325kA of surge with impulse of 8/20μs is generated and passed through the three phase 132kv transmission system. Arrester is placed at different locations (10m, 30m and 75m from transformer) and the simulation results are noted. The Simulation model is simulated using PSCAD software.
