Lightning is a random and unpredictable event. Globally, some 2000 on-going thunderstorms cause about 100 lightning strikes to earth each second. Information shows one homeowner's damage claim for every 57 lightning strikes. Annually in the USA lightning causes more than 26,000 fires with damage to property in excess of $5-6 billion.

Lightning strikes to earth, as presently understood, follow 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, people, 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.

3. Some Leader(s) likely will connect with some Streamer(s). Then, the "switch" is closed and the current flows. We see lightning.

What can United Electric do for you to help protect your investment from lightning damage? In Franklin's day, lightning rods conducted current away from buildings to earth. Lightning rods, now known as air terminals, are believed to send Streamers upward at varying distances and times according to shape, height and other factors. Different designs of air terminals may be employed according to different protection requirements.

You can't stop lightning, but you can prevent its destructive effects. For years, Lightning Preventor of America has designed and manufactured world-leading technologies that divert lightning ground strikes and prevent damage to buildings, property and people.

FARADAY CAGE
CONVENTIONAL SYSTEM
  • Requires a myriad of cable networks on roof
  • Protects only the structure to which it is affixed
  • More costly
  • Requires numerous downleads to ground
  • Requires a multitude of penetrations thru-roof
  • A static device, reportedly will not aid as anti-interference device
  • Tendency toward disturbing aesthetic qualities of architectural design
  • Multitude of sharp pointed air terminals on roof can prove to be dangerous to maintenance personnel or others with roof access.
