The research about lightning system with emphasis on lightning rods with blunt pointed in various size under the conditions specified. By using finite element method to analyze the electric field caused lightning rods, which showed that lightning rods were more effective than lightning rods, blunt tip. Since the electric field caused the blunt end than the tip. There is likely to be built as soon as possible the streamer In order to understand the working principle of the lightning protection system. This research is to explain the working principle, lightning, lightning protection system.
