The conventional lightning arrester consists of Copper rods. Their effectiveness is decided based on their position, morphology, materials used, and physical reaction that is performed due to the electrostatic field during the lightning.
The lightning arrester is placed at a dominant height, making it a favourable point for the lightning bolt to strike. Through the grounding system, the positive charge rises to the tip of the lightning rod. And when the lightning strikes, the device allows the lightning leader from the cloud and grounds it safely through the installed grounding system. Hence the current discharge gets distributed evenly throughout the ground and thus protects the structure.
