What are strike termination devices more commonly known as?

Strike termination devices are commonly referred to as air terminals. These devices are specifically designed to intercept lightning strikes and provide a safe path for the electrical energy to be directed down into the ground. Air terminals, often seen atop buildings and structures, play a crucial role in lightning protection systems by acting as the first point of contact for the lightning arc.

The effectiveness of air terminals lies in their ability to minimize the risk of damage to the structures they protect by allowing the lightning discharge to follow a controlled path, thus preventing direct strikes to vulnerable elements. They are strategically placed to maximize coverage and serve as part of a comprehensive lightning protection system that includes down conductors and ground connections for the safe dissipation of electrical energy. This designation emphasizes their primary function in the overall safety system against lightning hazards.
