What is the primary function of a lightning protection system?

The primary function of a lightning protection system is to conduct the electrical charge from a lightning strike safely into the ground, directing it away from trees and other structures. This is crucial because when a tree is hit by lightning, the intense electrical energy can cause severe damage through the vaporization of moisture, leading to explosive bark shattering and internal tissue destruction. By safely channeling this charge into the soil, the risk of damage to both the tree and nearby objects is significantly reduced.

This function is why properly installed grounding systems are vital. They ensure that the electrical energy does not travel through the tree, which could lead to extensive damage or even the death of the tree. The effectiveness of a lightning protection system lies in its design, which typically includes conductors, grounding electrodes, and bonding of metallic components, all intended to safely dissipate the energy away from the structure or living organism.

While attracting lightning might seem beneficial as a preventive measure against damage, it could actually increase the risk if not managed correctly. Likewise, providing shelter during storms does not address the specific risks lightning poses. Likewise, controlling tree decay is outside the purview of lightning protection systems, as they do not deal with biological issues but focus on managing electrical safety.
