What does a lightning protection system do?

Lightning protection systems and strike termination devices (rods) simply intercept a lightning strike and provide a safe and effective path that takes lightning’s harmful electricity to ground.

What is the purpose of a lightning protection system?

The function of an external lightning protection system is to intercept, conduct and disperse a lightning strike safely to earth. Without such a system a building’s structure, electronic systems and the people working around or within it are all at risk.

Do I need a lightning protection system?

Do all buildings need lightning protection? Few structures are required to have lightning protection, but any type of home or building can have it installed. Many well-known attractions are fitted with lightning protection, such as The White House, the Statue of Liberty, NASA, the Department of Energy, and many more.

How effective is lightning protection?

However, fast-forward 250 years to see that the advanced lightning protection systems of today claim 84% to 99% effectiveness, based on the desired level of protection. Below, we outline the basic steps and the corresponding components required to successfully prevent damage caused by lightning strikes.

What is the average cost to have a lightning rod installed?

Home Lightning Protection System Costs

Installing lightning protection systems in the home costs between $434 and $2,533, averaging most homeowners $1,482. The cost ranges from $100 for just a surge protector to over $3,000 for rods and grounding system.

Do lightning conductors work?

The lightning-rod system is an excellent conductor and thus allows the current to flow to ground without causing any heat damage. Lightning can “jump around” when it strikes. … The lightning can strike and then “seek” a path of least resistance by jumping around to nearby objects that provide a better path to ground.

Are lightning rods used today?

There is no good reason why lightning rods (and the associated assembly consisting of a connection to earth and a ground rod) are not routinely added to houses. … However, most high buildings and other structures do have some kind of lightning protection system incorporated into them.

How do you calculate lightning protection?

Length of Building (L) = 60 Meter. Width of Building ( W ) = 28 Meter. Height of Building (H) = 23 Meter.
