A Conventional Lightning Arrester is a conductor mounted on top of a building and connected to the ground through a wire or earthing strips, to protect the building at theconventional time of a lightning
If lightning strikes the building, it will strike the lightening protection rod, and be conducted harmlessly to ground through the wire, instead of passing through the building, A conventional spike lightning protection rod is a single component in a lightning protection system. In such a system, lightening protection rods are placed at regular intervals on the highest portions of a structure, a lightning protection system typically includes a rooftop network of electrical conductors, multiple conductive paths from the roof to the ground earthing, bonding connections to metallic objects within the structure and a grounding network. The rooftop lightning rod is a metal strip or rod, usually made of copper or aluminum and down path is made by Copper/Aluminium/GI strips or Wires. Lightning protection systems are installed on structures, monuments, bridges or water vessels to protect from lightning damage. Individual lightning rods are sometimes called finials, air terminals or strike termination devices.
