Lightning protection systems - What they do and don't do. A lightning protection system's only purpose is to ensure safety to a building and its occupants if lightning happens to hit it directly, a task accomplished by providing a good, safe path to ground for the lightning to follow.
How surge protector works. Surge protector diverts the excess voltage and current from transient or surge into grounding wire and prevents it from flowing through the electrical and electronic equipments while at the same time allowing the normal voltage to continue along its path.
