Lightning Protection for Homes

Facts of Lightning
Lightning is a natural phenomenon caused by separation of electrical positive and negative charges by atmospheric processes. When the voltage difference between separated charges gets very large, the air between the positive and negative regions breaks down in a giant
spark. The resulting current flow ionizes and heats the air along the path to 54,000° F. The ionized air glows brightly (the LIGHTNING), and the sudden increase in temperature expands the channel and nearby air, creating a pressure wave that makes the THUNDER.

  • The cloud-to-ground voltages leading to the discharge are tens of millions volts or more.
  • The peak discharge currents in each stroke vary from several thousand amperes to 200,000 A or more.
  • The current rises to these values in only a few millionths of a second.
  • Major part of each stroke usually lasts much less than a thousandth of a second.
  • Each visible event, referred to as a flash, typically consists of 1–6 (or more) individual strokes.
  • Cloud-ground strokes have been recorded reaching as far as 18.6 miles horizontally from the base of the cloud.
  • Cloud-ground flash density in the Gulf Region can reach ~37 flash/mi2 per year.


People generally think of lightning damage as what happens at the point where a cloud-ground stroke terminates on a tree, structure, or elevated wiring. the lightning current pulse continues into conductive parts of the structure, cables, and even underground wiring and pipes. Lightning impulse is so strong, equipment connected to cables a mile (1.6 km) or more from the site of the strike can be damaged. How does lightning create damages? Read more


Damage from Lightning
There are primarily FOUR WAYS a lightning can damage property and equipment:

  1. Lightning strike to the network of power, phone and cable television (CATV) wiring. Lightning can also travel through the ground (soil), reaching underground cables or pipes.
  2. Lightning strikes to, or near, the external wiring network common to most suburban and rural houses. Air conditioners, satellite dishes, exterior lights, gate control systems, pool support equipment, patios and cabanas, phone extensions, electronic dog fences, and security systems can all be struck by lightning, and the lightning surges will then be carried inside the house by the wiring.
  3. Lightning may strike nearby objects (trees, flagpoles, signs) that are close to, but not directly connected to the house. In this situation, the lightning strike radiates a strong electromagnetic field, which can be picked up by wiring in the house, producing large voltages that can damage equipment.
  4. A direct lightning strike to the structure. It can severely damage a structure without a lightning protection system (LPS), and will generally damage most electronic equipment in the house.

 




Lightning Protection System

LES designs and installs a 4 POINT Enhanced Lightning Protection System:

1. Structural Lightning Protection System: The lightning strike attaches to the tip of the air terminal, and the lightning current flows via the down conductors into the lightning ground system, which is bonded to the building ground.

2. Lightning Protection on Power Line point-of-entry: They collect the major part of the lightning currents coming in on external wiring, and direct them harmlessly into the building ground. They also limit the lightning voltages that get inside the building, and greatly reduce the burden on the point-of-use protectors, at the equipment.

3. Lightning Protection on Communication & Signal Line point-of-entry: They collect the major part of the lightning currents coming in on external wiring, and direct them harmlessly into the building ground. They also limit the lightning voltages that get inside the building, and greatly reduce the burden on the point-of-use protectors, at the equipment.

4. Lightning Protection at the point-of-use of critical electronic equipment: These act as the final line of protection for critical electronics such as Air conditioners, satellite dishes, exterior lights, gate control systems, pool support equipment, phone extensions, electronic dog fences, and security systems.

 

Lightning Protection Services

Lightning Elimination Systems, based in the gulf coast region since 1996 is a speciality lightning protection contractor that designs, installs and maintains customized lightning protection, surge suppression, grounding and bonding systems. We are the only independent lightning protection  company in the region with extensive experience in all three lightning protection technologies available today - conventional, early streamer and static dissipation.

1. Site Visit: LES performs an on-site visit. During the visit we inquire about your most critical lightning damage concerns and collect measurements on the facility.

2. Report: We compile a report detailing our findings, including photo documentation. It also included details for bringing a system into compliance and estimated budget to provide an installed solution.

3. System Design: Using the information collected, LES engineers design a system to protect life, property and sensitive electronic equipment.

4. Product Selection: After a system is engineered, we select components for enhanced lightning protection.

5. System Installation: Our group of in-house installers, assure the system installation is as engineered.

6. Maintenance: LES confirms that your system remains in compliance by performing annual inspections and maintenance.
