Lightning Protection Systems for Businesses
Today’s lightning protection systems are a modern interpretation of the lightning rod. Also known as lightning control systems, they’re designed to channel electrical charges away from electrical systems and reduce the risk of structural damage. While commonly implemented in many parts of the US, lightning systems have built considerable mythologies around attracting lighting and other purposes that just aren’t true.
How Does a Lightning Protection System Work?
Lightning systems establish a more direct route to the ground for the lighting’s electrical charge to follow. Systems vary by building or structure, but they all share common components, including:
Rods – Also known as air terminals, rods are vertical posts installed on or near the highest point of a building. There are various shapes of rods, though there’s little evidence rods of a certain shape or material are more conductive than others.
Conductor cables – These are thick metallic cables that connect the rod to the ground. In most cases, conductor cables are run along the roof and down the nearest corner of the building.
Ground rods – The subterranean counterpart of roof rods, ground rounds link to cables and direct the electric current far underground.
What Lightning Systems Actually Do
There is considerable misunderstanding around the purpose of lightning strike protection equipment. A well-designed and maintained system will reduce the risk of fire damage or structural damage.
It’s important to understand what these systems will not do.
They do not attract lightning. In fact, there’s considerable debate on whether air terminals have any real impact on attracting or focusing lighting. The conductor cables and ground rods are much more important to the system.
They do not “absorb” lightning. These systems create a safe, direct path to the ground. They do not dissipate lighting charge in any way.
They do not provide surge protection. Lightning protection systems do not shield valuable electronics directly, although they do play an important role in mitigating the risk of lighting forcing a surge by directing it away from electrical circuits.
Combining Lightning Protection Solutions
Just as lightning systems do not provide surge protection, even industrial surge protection systems are no match for a direct strike. Industrial and commercial buildings rely on both systems to reduce the risk of electrical damage. As more businesses rely on intricate electrical equipment, computers, and data, the lighting protection industry has grown quickly. Valued at $891 million in 2022 in the US, industry experts forecast a steady 5.5% CAGR through 2030.
Lightning strike damage is covered by most business insurance policies but be sure to talk with your agent about your policy. While coverage may replace damaged machines or cover facility repairs, businesses still face revenue losses as assets are repaired or replaced.
