  • What Is Electrical Grounding Or Earthing

    Jan 20, 2021 The earthing device is in the form of lightning arrestors, which are placed at the highest point of the building and connected to the ground via a conducting wire or plate. In the scenario when lightning strikes a building, the copper lightning arrestor draws in the jolts of lightning and transfers that massive amount of energy to the ground, thus preventing any damage to the structure or harm to its
