We can’t do anything about the lightning strikes, except installing better earthing protection systems in lightning prone areas. For decades, Franklin lightning arresters, also known as the Franklin rods, have been widely preferred for earthing systems.
But, what exactly are the Franklin lightning arresters? How do they protect buildings? And where are these traditional arresters used? This blog will give you the right answer in brief.
What is a Franklin Lightning Arrester?
Franklin lightning arresters were invented by Benjamin Franklin around 1749 or 1752. Although these arresters are old fashioned, they still are highly effective when used to protect building structures from natural lightning jolts. The arresters are mounted on top of the building or particular structures that directs the surge energy to the ground safely.
How Franklin Lightning Arrester Works
The rod of the arrester mounted at the top of the structure catches the potential lightning strikes. It prevents the striking of other vulnerable parts of the structures.
When the strike is captured it needs to be dissipated into the ground. Here, a conductive path of down conductor comes into the picture. It is connected to the arrested and extends all the way to the earthing system.
The surge energy is dissipated into the earthing system through an earthing pit or grid means the risks of fire hazard or equipment damage are minimized.
The Franklin arresters create a protection zone around the building, ensuring that the structure, electrical systems, and people are shielded from the lightning strikes.
Why Choose Franklin Lightning Arresters
When you are looking to safeguard small, simple structures from lightning strikes, you wouldn’t want to invest in expensive ESE arresters. Here, Franklin lightning arresters are highly preferable. They offer long-term stability in power supply and safety without much repair expense. You can think of it as a small investment with a big payoff in protection.
