A Lightning Arrester can be-

Lightning Rod:

  • This is the most common type. Imagine a metal rod (sometimes with a fancy tip) on your building’s peak. It attracts lightning and safely conducts it to the ground through copper strips.

Overhead Wires:

  • These are used for specific areas like rocket launch sites or power lines. Imagine taut wires stretched above the area, intercepting lightning before it hits anything below.

Faraday Cage:

  • This is for super important buildings with sensitive equipment (like computer rooms). Imagine a metal mesh cage surrounding the entire building, creating a protective shield that conducts lightning safely away.

How does Lightning Arrester for Buildings Work?

Here’s a breakdown of how it works:

  • Air Terminal: This is the part most people recognize as a lightning arrester. It’s a metal rod, typically made of copper or aluminum, mounted at the highest point of the building. Its purpose is to attract a lightning strike.
  • Conductor: A thick cable made of copper or another conductive material runs from the air terminal down the side of the building. This cable provides a low-resistance path for the lightning current to travel.
  • Earthing: The conductor is connected to a grounding electrode system buried in the earth. This system safely disperses the lightning current into the ground.

By providing a preferred path for the lightning strike, the lightning arrester system protects the building from the immense voltage and heat that can cause serious damage.

Lightning arresters are particularly important for tall buildings, but they can be beneficial for any structure in an area prone to lightning strikes.
