The simplest way to think of a lightning strike would be as a short circuit between the cloud and the earth. The earth and an active thundercloud have either a positive or negative polarity with respect to each other, just like battery connections that can arc, if they are not separated by a long enough air gap.
LEC is a fully integrated lightning protection solution provider, offering a patented set of solutions to mitigate lightning strikes.
Our systems use multiple technologies to redirect and dissipate lightning strikes.
Some designs use streamer delaying air terminals to collect strikes only when charge transfer capacity is exceeded by dissipation requirements of the Dissipation Array System (DAS).
DAS uses the principle of point discharge to facilitate the dissipation. The purpose of charge dissipation products is to reduce the accumulation of electric charge and thereby prevent an electric arc that can cause damage. This is accomplished by ionizing surrounding air and neutralizing accumulated charges on the earth’s surface, including the grounding system.
We offer holistic services that include system design product specifications, product manufacturing, technical support, installation and site testing. LEC’s lightning protection design and engineering team can produce complete lightning protection and grounding layout for any type of structure using the latest CAD software. Our estimates are detailed to list out all inclusion and exclusions and each estimate adheres to all required specifications.
Even before the estimates are submitted we understand the electrical specification and relevant architectural drawings of your facility. Then with the backing of our experienced lightning protection design team, we send drawings, bill of materials required, installation, testing and commissioning estimates.
Lightning protection is necessary across the world and we are dedicated to providing lightning protection and prevention products, solutions and services as par with the international standards.
When lightning strikes an object, it is looking for the path of least resistance, or more specifically, the path of least impedance.
A grounding system, which is made up of a grounding rod and wires, provides a low-impedance path to the ground.
This low-impedance path is installed to encourage the lightning to travel through it instead of through your expensive electronic equipment.
Grounding rods and wires are also used to create what is referred to as a common ground.
One way of creating a common ground is to drive a copper rod into the ground and connect your electrical and electronic equipment to this rod by using wires or straps (grounding wires). The grounding rod should be at least 6 feet long and should be fully driven into the ground, leaving enough of the rod accessible to attach the ground wires to it. By creating a common ground, you have created a path of least impedance for all of your equipment should lightning cause an electrical surge.
How can we help?
Improper grounding accounts for a large percentage of damage of sensitive electronic equipment.
Multi-grounding renders equipment susceptible to lightning induced transient over-voltages as well as steady-state noise caused by ground loop currents.
These problems can be avoided by

Today’s digital economy relies on fast and reliable telecommunications networks. Such telecommunication towers are obvious and known targets for lightning strike damage, which has caused significant service downtime over the years. Therefore, protecting communications and meteorological towers should not be an option, but a necessity.
In this article we discuss the importance of grounding rod in the lightning protection system to protect communications and meteorological towers.
A good ground is very important, maybe the most important thing, in mitigating lightning damage; more energy diverted to ground means less can go through your electronics! But conventional grounding rod is typically insufficient for use where target resistance can be less than 1 ohm.
WHAT IS GROUNDING?
The NEC article 100 defines ground as:
“A conducting connection, whether intentional or unintentional, between electrical circuits or equipment and the earth, or some conducting body that serves in place of the earth".”
WHAT IS BONDING?
The NEC article 100 and 250-70 defines bonding as:
“The permanent joining of the metallic conducting parts of equipment and conductor enclosures to assure and electrically conductive path between them that will ensure electrical continuity and have sufficient capacity to safely conduct any foreign current likely to be imposed to ground.”
WHAT IS A GROUNDING ROD?
Ground rods in a well-conducting soil have a cylindrical region of influence around them with a diameter that extends roughly twice the length of the ground rod. This is the region in which the ground rod disperses lightning strike energy.
A ground rod is usually located very close to your main electrical service panel and is often made of copper or copper coated steel. They’re approximately ½” in diameter and eight to 10 feet in length. It must be electrically tied to your main service panel to provide an approved ground connection.
Proper Grounding and Bonding are Crucial
Efficient grounding systems reduce the risk of electrical arching and fires.
Our patented grounding rod improves reliability for many applications including:

When it comes to lightning protection, many people think of Benjamin Franklin’s experiment of flying a kite in a lightning storm. Franklin did usher in the thinking that buildings could be protected from lightning. While he used a simple metal rod to safely direct the electricity, today’s lightning protection design and systems are a little more complex.
Lightning protection is becoming more and more important because the climate has changed in recent years and lightning occurs more frequently. External Lightning Protection can be designed on a facility to protect it from direct lightning strikes. International standards and recommendations from IEC, NFC, UNE, UL, IEEE govern on how these systems are designed and installed. The external protection system comprises of an air terminal network, down conductors and earth termination system. Various types of air terminals and earth termination products are manufactured by LEC.
Below are some very important considerations for lightning protection design systems:
Accurate data plays a very important role in designing a lightning protection system and is the important deciding factor in the later stage of the design. So, the crucial data to be collected involves dimensions, location and environmental factors of the building/ structure.
We offer a complete risk analysis service that includes earth resistivity tests and structural external and internal risk assessment in terms of international standards. These risk analysis reports include all technical drawings and illustrations.
LEC designs internal and external lightning protection systems that range from simple office and administration buildings to large industrial plants for all types of industry sectors such as, photovoltaic plants, petrochemical industry, oil and gas industry, data centers, etc. LEC has patented quality products and over 40 years of experience.
Manufacturing and installation
Only once we have confidence that the lightning protection design parameters are met, we will start a full “for construction” design followed by manufacturing, installation and inspection.
Most older lightning protection systems are interception systems that don’t reduce the odds that lightning will strike a building. Instead, they mitigate the risks of a lightning strike by controlling and harmlessly dispersing the energy they create. These systems are intended to guide the lightning discharge safely to the ground, ideally without impacting anything inside. However, Our Dissipation Systems are designed to prevent lightning strikes to your facility. They use a charge dissipation terminal to release the static building up near the ground during thunderstorms. Without that charge, a streamer cannot form. Therefore, the whole area is an unappealing target for lightning, and it will instead strike somewhere outside of the range of the system, where it can meet a streamer.

The starting point in lightning protection system design is an assessment and calculation of the actual risk from a potential lightning-related damage. Lightning Eliminators provides comprehensive lightning risk assessments and lightning protection plans that will help to ensure that a lightning strike will not cause catastrophic failures, injuries or fatalities at equipment facilities. Our lightning risk assessment and proposed lightning protection plans illustrate the current risks and necessary steps that should be taken in order to meet international standards and guidelines.
Possible consequences of lightning striking on an unprotected building include:
We provide solutions that don’t collect a strike, because that is equally as dangerous as the consequences of not protecting your facilities or it could end up costing you more than you ever.
Our lightning protection design plan for you:
One important thing to remember is that lightning protection design solutions should be tailored to the needs of the individual facility. When analysing lightning risk, LEC engineers start by asking the client about their goal – particularly if the answer is to avoid any lightning-related problems at all, then the engineering group does an on-site design study to analyse vulnerabilities and formulate a tailored solution.
Risk analysis should include grounding as well. LEC’s Smart Ground test analyses the in-situ grounding environment and compares the actual measurements to an electro-geometric computer model of the system being tested.

History of lightning rod protection
Benjamin Franklin’s passion for researching electricity led him to pay attention to a phenomenon that had gone unnoticed by many others before him. One day, he was flying a kite when it was struck by lightning that burned it up, which led the ingenious researcher to wonder if it were possible to attract lightning bolts in some way.
He tied a metal key to his kites and continued flying them on stormy days until he was able to capture a bolt. Electricity went down the string of the kite until reaching the key. That is how he demonstrated that it was possible to divert lightning bolt to a metal, thus sparing other elements from being struck.
Evolution of Lightning rod protection
For over 50 years, LEC has been providing advanced lightning protection systems worldwide. The advanced systems LEC designs, manufactures and applies do not provide the traditional Franklin Rod protection schemes. Rather, we take the view we should avoid the strike, not collect it.
Our lightning rod uses a naturally occurring, scientific phenomenon called point discharge to retard the collection of lightning within a finite protection zone. Thus they should be inspected and maintained regularly.
Lightning rod protection and maintenance
Lightning rods must undergo periodic tests and maintenance. This allows the detection of deviations from the reference standards or anomalies in the installation caused by environmental conditions such as corrosion, incorrect handling such as sectioning or robberies, or other circumstances such as expansions of the building where the lightning rod is located.
We offer a comprehensive inspection, test and maintenance service for earthing and lightning rod protection systems. With our fully trained test engineers, you can rest assured that the earthing and lightning protection test and maintenance requirements are in safe hands, and that your system, if maintained correctly, will protect the building and the people and equipment within it, whenever it is called upon to do so.
During lightning rod protection and maintenance we check for:

Lightning usually hits the sharpest and tallest object in an area because ground charges emitted from objects with high elevations reach the opposite charged streamers of the cloud earlier than the charges from any shorter object. On the other hand, lightning current aims to reach ground by following the shortest and most conductive way. That’s the reason; a tall structure such as a wind turbine in a wind farm is vulnerable to the effects of a direct lightning strikes.
If reliable supply is to be maintained it is important that the design and installation of a lightning protection system (LPS) for the wind turbine be done correctly.
Wind Turbine and Lightning
With the growing awareness of the global warming and the limits to our fossil based fuels, the need to find better renewable source of energy is becoming apparent. The use of wind energy is a rapidly growing industry. Over the past few decades, the number of wind farms has grown dramatically, beginning with the first large (utility-scale) wind farm installed in California in 1980. By 2008, the U.S. installed capacity reached 25.4 GW and according to the U.S. Department of Energy, the installed capacity of wind power in the U.S. reached 74 GW.
Lightning is particularly likely to strike wind turbines due to their exposed location, height and complexity. As lightning strikes often cause considerable material and economic damage; thus understandably, most wind owners and operators breathe a sigh of relief when a major storm passes their wind farm without damage to a turbine.
Lightning protection system for Wind turbine
The chief objective of a lightning protection system is to prevent lightning from damaging the rotor blades, bearings and electrical systems.
When planning lightning protection measures, not only cloud-to-earth flashes, but also earth-to cloud flashes, so called upward leaders must be considered.
This is where LEC’s IPG (Ion Plasma Generator) comes into picture
During lightning conditions, the IPG acts as the most attractive object in the protected area by using the storm’s energy to develop dense corona plasma. As the electrical field grows, this highly charged corona becomes more attractive, drawing strikes safely to the IPG and preventing damage to valuable assets.
Unlike traditional collectors that often fail to exert enough attractive influence on approaching strikes, the IPG’s materials and construction are optimized for maximum risk reduction on a cost effective and durable design.
IPG is a crucial component in ensuring the best lightning protection to a wind turbine. For any further questions or queries, contact us!
All too often when lightning strikes an industrial plant, equipment is damaged and operations curtailed. There is an initial rush to get the plant operational again. This is a reasonable response. By taking a systematic approach, applying international standard, carrying out a risk assessment, then acting upon the results of that risk assessment both cost effective and successful solutions can be found.
