Abstract—Lightning is a natural phenomenon in which large amounts of electricity are discharged from one location to another through open air, resulting in a bright arc of light. During an electrical storm, clouds begin to build up powerful electric fields, eventually ionizing the air around them and developing a powerful current. These areas, called step leaders, form paths of ionized air (or plasma) that slowly make their way toward the Earth. If a step leader makes contact with another ionized path, called a positive streamer, it creates a completed path for the plasma to travel on, allowing the accumulated current in the cloud to travel between the two points. This results in a lightning bolt and an explosion of air, which we call thunder. This project discusses the steps to design earthing and lightning protection system on building. The building is made strong and resistive against lightning strikes by making the building as negatively charged structure with use of cathodic protection materials and coatings. In addition, treating the problems that affects the structure gets reduced by lightning protection method which are determined by experiments and case studies.
