An air-termination system is installed at the top of the protected object and connected to a grounding grid buried underground with a wire that meets the specifications. The specifications of the lightning rod must comply with national standards, and the height specifications required for each lightning protection category are different. When a thundercloud discharges close to the ground, it distorts the ground electric field.
