Lightning conductor conduct a lightning strike from a concrete or tile roof of a structure (house or building), by way of heavy copper or aluminum wires, to rods driven into the grounds, thereby protecting the structure that they are applied to from the lightning itself safely to the ground. It is not true that a lightning conductor attracts lightning. They also do not prevent lightning from striking a house or other structure to which they are attached to, but guides the damaging energy from such a strike safely to the ground and avoid the danger and damage as far as possible.
Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance. Picture 1 A lightning conductor carries the charge safely to ground. Copper wires allow electric current to flow without much loss of energy.
The lightning-rod system is an excellent lightning conductor and thus allows the current to flow to ground without causing any heat damage. Lightning can “jump around” when it strikes. This “jumping” is associated with the electrical potential of the strike target with respect to the earth’s potential.
Lightning rod types, Vertical rods or masts for example: from 2m to 30m in height create lightning protection zones that extend in a 45° cone from the rod’s tip.
Lightning conductors typically have an upward pointing spike. The other end is attached to Ground through a low resistance band of copper conductor. The aim is to short circuit the electrical charge that builds up in the atmosphere, bypassing the fabric of the building.
