Lightning Energy
Lightning is a capricious, random and unpredictable event. Its' physical characteristics include current levels sometimes in excess of 200 kA and speeds approaching one third the speed of light. Globally, some 2000 on-going thunderstorms cause about 100 lightning strikes to earth each second.
Because of its heavy investment in equipment (towers, electronic equipment, and satellite dishes), lightning is a major concern for the industry. A broadcast tower, typically the tallest structure in its area, is a prime target of lightning. If your tower or other facilities are a target of lightning strikes, the lightning will destroy your tower as well as the electronic system inside the tower. To avoid these unwanted effects, you should evaluate your lightning protection system.
Lightning is a product of electrically charged storm clouds. The charged clouds induce an opposite charge (ground charge) on the surface of the earth beneath it as they travel through the atmosphere. When the ground charge reaches a structure, the cloud charge pulls it up onto the structure, concentrating the ground charge on and around it. If the ground charge builds to a level exceeding the dielectric (insulation resistance) of the intervening air, an arc or lightning strike will occur. The process begins with stepped leaders branching down from the clouds. When they come within close proximity to the ground, approximately 500 feet, the electric field intensity at ground level becomes so strong that objects and structures begin to break down electronically, shooting streamers up toward the stepped leaders. When a streamer and a stepped leader connect, a path is created for a lightning strike.
The phenomenology of lightning strikes to earth, as presently understood, follows an approximate behavior:
1.The downward Leaders from a thundercloud pulse towards earth seeking out active electrical ground targets.
2. Ground-based objects (fences, trees, blades of grass, corners of buildings, Towers, lightning rods, etc., etc.) emit varying degrees of electric activity during this event. Upward Streamers are launched from some of these objects. A few tens of meters off the ground, a "collection zone" is established according to the intensified local electrical field.
