DIRECT STRIKE

摘要

WHEN LIGHTNING STRIKES A BUILDING, facility owners are either grateful for their lightning protection system, or wish they had one. That is more true today than ever-as weather gets more extreme, lightning strikes more common and buildings more sophisticated, so too must the lightning protection and grounding systems designed to protect them. The adage that lightning doesn't strike the same spot twice is proven wrong by Mother Nature, again and again. In fact, said Jennifer Morgan, director and secretary/treasurer of East Coast Lightning Equipment (ECLE), Winsted, Conn., some buildings sustain multiple strikes a year. For example, the Empire State Building is struck nearly two dozen times each year. At the heart of each lightning protection system (LPS) installation is the prevention of disasters-the kind that appear on the news.
