Lightning Protection System – Protect your Assets from Lightning Damage

-

Lightning is a final result of the natural creation of an electrical charge imbalance in the Earth’s atmosphere.


Lightning occurs both within the atmosphere, cloud-to-cloud lightning, and from the atmosphere to the earth, sky to ground lightning or the reverse, ground to sky discharge. Regardless of the direction of the lightning stroke, a great deal of energy is released as the electrical charge balance of the atmosphere-earth is restored. An average lightning strike consists of three strokes, with a peak current flow of 18,000 amperes for the first impulse and about half that amount of current flowing in the second and third strokes.


A lightning protection system is designed to protect a structure from damage due to lightning strikes.


Lightning protection components at a glance:

  • An air terminal, down conductor, and at least one ground plate or rod for each beacon tower, should be installed.
  • The air terminal should be installed at the top of the tower with the tip of the rod extending not less than 150 mm (6 in) above the top of the beacon.
  • Down-conductor cables should be securely fastened to the surface of the tower leg with suitable bronze fasteners having bronze or noncorrosive metal bolts. Sharp turns or bends in the down conductor are not permitted.
  • All connections of cable-to-cable, cable-to-air terminals, and cable-to-ground plates or rods must be made with solderless connectors or noncorrosive metal.
  • The down-conductor cable shall be securely attached to ground rods or plates. The ground rod shall be driven into the ground so that the top is at least 150 mm (6 in) below grade. The down-conductor shall be firmly attached to the ground plate or rod by means of a ground connector or clamp.


How to reduce lightning damage by lowering the incidence of a direct lightning strike to buildings, communication towers, electric utility substations, industrial facilities, etc?

By using a powerful tool like

Charge Dissipation - This is a scientific process first touched on by Benjamin Franklin more than two centuries ago. However, since then, and most notably over the last twenty years, the technology of static charge dissipation has developed to the point where damage to electronic equipment can be reduced or eliminated, depending on the site protection systems selected. Many sites have never had a recurrence of a direct lightning after installing a properly engineered lightning production system.



Today, there are several types of code-compliant lightning protection systems in use, and they should always be installed by trusted and certified lightning protection companies like Lightning Eliminators.

The Importance Of Maintaining A Lightning Rod Protection System

-
Lightning rods must undergo periodic inspections and maintenance, as indicated by national and international regulations. These periodic inspections allow the detection of deviation from reference standards or anomalies in the installations caused by environmental conditions such as corrosion, incorrect handling or expansion of the building where the lighting rod protection is installed.  Maintenance of an effective lightning rod protection system is essential due to the following: -    Efficiently dissipate heavy fault currents and electrical surges, both in magnitude and duration, to protect equipment being damaged so as to minimize downtime, service interruptions and replacement costs -    Provide a stable reference for electrical and RF circuits at the installation to minimize noise during normal operations -    Protection of personnel who work within the area from dangerous electrical shocks For a lightning rod protection system to work optimally, each and every part needs to be i

Lightning Protection Products You Never Knew You Needed

Dissipation Systems are designed to prevent lightning strikes. These refer to devices using point discharge phenomena to retard and reduce the potential of lightning strikes on their protected devices. Choosing the appropriate lightning protection products for a specific application requires several performance issues to be considered, such as the radius of the dissipater electrode cross-section, the construction material of the dissipater, the number and density of electrodes, and the configuration of the dissipater on the structure it is designed to protect.  The Dissipation Array System (or DAS) is a lightning prevention system. Well, it doesn’t prevent lightning from happening altogether, but it does prevent lightning from striking the protected structure. There is a lot of detail on how it does this, but the simple version is that it lowers the electrostatic field in the protected zone. This prevents upward-rising lightning leaders (or streamers) from being created on the pro

  We are Pioneers in: ·          Lightning Protection System ·          Chemical Earthing Installations ·          Lightning Surge Protection Devices Let’s talk about our patented lightning surge protection devices . The term surge protection device (SPD) describes electrical devices typically installed in power distribution panels, process control systems, communications systems, and other heavy-duty industrial systems, for protection against electrical surges and spikes, including those caused by lightning.  When clean, uninterrupted power is crucial, LEC’s next-generation surge protection devices are ready to provide the highest level of performance for the safety and reliability of your electrical systems. These devices are able to accomplish two tasks for protection, i.e., surge voltage in terms of amplitude needs to be limited and discharge of the surge voltage to the ground, which is done without causing any damage to the devices.  Lightning Surge Protection Devic
