Lightning protection system (LPS) is installed to provide a safe path for lightning energy from a lightning strike to reach earth and protect the structure or building from high voltage currents from the lighting strike. Today, lightning protection systems are in use on towers, space shuttle launch pad, factories and buildings. Lightning Protection System or LPS mainly consists of four parts, which are surge suppressors, copper air terminals, copper clad ground rods and copper cable. The cable and air terminals used are commonly made of copper, but aluminium can also be used for its manufacture. The cable and the ground rod are the most important parts of the lighting protection system as they allow the current to pass to the ground. Without a designated path, lightning may conduct through conductors installed in the building, which include cables, phone lines, gas pipes, phone, electric lines or water pipes to reach the ground. This is hazardous to the building as well as living beings.
