Lightning protection should be provided in the following areas:
- In areas where lightning can occur often.
- Buildings located in exposed areas.
- Height of building is more compared to the surrounding buildings and places.
The lightning-protection system consists of an unbroken chain of conductors from the roof of a building to the ground. This provides an easy path for the heavy electrical power released by the lightning to discharge to the earth in the shortest time possible.
The conductor should be pure copper. The conductors should be of shortest length without sharp bends, kinks, etc. The area of influence of a lightning conductor is assumed to be a cone with the top most point of the conductor as the apex and a radius related to the height of the apex. This radius may be taken as equal to the height of the conductor on a safe side.
