Lightning - History and Discovery

Every year millions of dollars are spent by various companies to get suitable protection against surges that resulted from faulty earthing conditions and lightning.
Lightning is a phenomenon that has no prevention methods invented so far. However protection and damage reduction methods have existed with in the last two centuries.

Lightning existed as an unknown mysterious” fireballs “falling from the sky high, until the mid 18th century, when a scientist Benjamin Franklin solved the mystery by proving to the world with his world famous Kite experiment that lightning is produced simply by an interaction of two unlike charges. Hence it is simply a discharge of a fully charged electric cloud to the ground earth mass.

Inventors have invented several methods of protections and accessories, that are utilized to shield the gigantic electric current that flows in a lightning or fault earth, are readily available in the existing market.

In a world of increasingly sophisticated buildings and equipment, lightning is a constant risk. Telecommunication sites and buildings are considered as high-risk area for lightning and faulty earth due to sophisticated equipments that are used in the industry. There for in general all telecommunication stations should be provided with an appropriate Earthing and lightning protection system designed to safeguard against, or reduce the risk of a lightning strike, or an electrical fault becoming a hazard to personnel, equipment, or structures.
