Abstract
The world’s hunger for energy is a growing matter of concern. The people need to find a sustainable amount of energy to meet the world’s future needs and demands. The amount of energy generated from renewable energy sources need to be increased. Many types of renewable energy sources have been used in many countries today. However, there are still no country using lightning as an alternative energy source. Lightning is a very impressive phenomenon that occurs naturally and contained enormous amount of energy in a single stroke. This paper demonstrates the simulation of lightning impulse system using PSPICE software. The main objective is to determine the ability of lightning as energy source generated from renewable sources. The overall lightning impulse system consists of arrestor, transformer and a battery. Since lightning is not applicable in PSPICE, it is designed using equivalent circuit referring to IEC Standard 60060-1. The high voltage from lightning is then stepped down using transformer with a set of impedance to suppress high magnitude of current flow to the system. The ability of lightning as power source is determined through the study of the magnitude of changes variant appears on the battery.
