What is the primary purpose of lightning protection?

The primary purpose of lightning protection is to safeguard both the structural integrity of buildings and their electrical systems. Lightning can strike a structure, leading to significant damage through high-voltage surges, which can cause electrical fires, destroy sensitive equipment, or even compromise the overall safety of the premises. A properly designed lightning protection system directs the electrical energy from a lightning strike safely into the ground, minimizing risks to the building itself and its inhabitants as well as protecting electrical installations from surge damage.

While preventing fire caused by lightning and ensuring the safety of electrical equipment are indeed outcomes of an effective lightning protection system, the overarching goal is to provide comprehensive protection for the structure and all its integrated systems. Other options regarding aesthetics or efficiency do not align directly with the functional purpose of lightning protection, thus highlighting that the core focus remains on structural and electrical safety.
