The highly charged clouds, charged with high density of electrons on the outer layers of the clouds in ionised state , induce opposite charge around the lightning conductor almost equally opposite to the potential of charge in the cloud. This makes the lightning to get attracted towards the accumulated opposite charges around the lightning conductor, which, in a way, creates a virtual path for the lightning to drain out the high potential electric charge along the conductor.

The highly charged clouds are charged with high-density ionized electrons on the outer layer, which induce opposite charge around the lightning conductor and is nearly equal to the potential present in the cloud. This phenomenon attracts the lightning towards accumulated opposite charges around the conductor, creates a virtual path for the lightning to drain out the high potential electric charge along the conductor.
The lightning rod is placed on the top-most corner, where the lightning rod is mounted on a mounting base and connected to an earthing rod or a ground rod through a copper cable.
The lightning absorbed by the lightning rod is diverted through this path by avoiding any damage to the structure. The sole purpose of a lightning conductor is to offer a low resistance path to the lightning and allows it to pass through the ground without impacting the physical structure. Protection from lightning is essential to safeguard human, structures, transmission lines, electrical equipment by controlling different types of risks from thermal, mechanical and electrical hazards of the lightning flash current.
The risks include risks to a person as well as to structures and internal equipment. Lightning always finds a way to flow through the best conductor and flow through it where the medium might be a tree or a building. When the fully charged cloud passes over the lightning conductor, the electric charge will flow down until the cloud is fully discharged. Therefore, there will not be any flash or sound of thunder during this process. To get a quote or to talk to our industry expert visit our contact us section.
