If you operate in a region where seasonal lightning strikes are common you’ll know how critical it is that your sensitive electrical equipment features lightning protection!
Lightning is produced in thunderstorms when liquid and ice particles above the freezing level collide, and build up large electrical fields in the clouds. Once these electric fields become large enough, a giant “spark” occurs between them (or between them and the ground) like static electricity, reducing the charge separation.
Lightning bolts have tremendous forces of energy. A single lightning strike can have anything between 100 million to 1 billion volts. If your property or building is hit by a lightning strike, it’s easy to see how such a force of energy could cause serious damage.
Since, we cannot prevent the occurrence of lightning strikes or where they occur, the next best thing is to put protections in place to prevent personal and property damage. The purpose of a lightning protection system is to control the passage of the electrical current in a safe manner.
A lightning protection system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground for potential strikes.
- A basic lightning protection system would provide a conductive path between an air terminal and earth, so that most of the lightning’s current will follow the path of the lightning protection system.
- Lightning rods or air terminals capture the strike at a preferred point and then conduct the energy to the ground and away from the building, minimising the risk of damage.
- Down conductors connect the lightning rod system to the earth termination system. Down conductors create a path for the lightning's energy to travel along.
- The successful performance of the entire lightning protection system depends on an effective earth termination system. The earthling or grounding system is responsible for the dissipating the lightning’s energy into the ground, and ultimately away from your property and people
Our ‘No-strike warranty’ backed lightning protection system
Dissipation Array System (DAS) prevents direct lightning strikes within a designated area of protection and LEC’s “No-Strike” warranty ensures complete protection on all LEC supervised installations.
It prevents direct lightning strikes by reducing the electric field to below lightning-collection levels, within the protected area. As a result, DAS helps to prevent downtime and loss of assets, while increasing personnel safety.
As your facility grows and expands, we work with you to evaluate how your system is affected, recommends necessary changes and works with you to ensure uninterrupted state-of-the-art lightning protection. Contact our elimination expert today.
