In early wind turbine installations, lightning was not considered a threat, or the nature of the threat was not well understood; however over recent years there have been a large number of lightning strikes reported to wind turbines and in many of these there have been instances of severe damage.
In particular the blades are subject to catastrophic damage, and because of both material and installation costs, any damage to the blades is expensive. A significant other area of damage or disruptions is where lightning affects electrical systems and control circuitry. Statistics show that lightning damage is a major contributor to down-time in the operation of wind farms and the most common insurance claim filed by wind farm owners.
Lightning protection design system is the best solution
Purpose of applying this solution is to attract lightning on arresters and not to let lightning hit any other spot on wind turbine.
The function of an external lightning protection design system is to intercept direct lightning strikes to the tower of a wind turbine and to discharge the lightning current from the point of strike to the ground without causing thermal or mechanical damage or dangerous sparking which may lead to fire or explosion and endanger people.
Our offer to you
To minimise risk of downtime caused by lightning strike, LEC manufactures and certifies lightning protection design systems in accordance to relevant international standards.
Our protection measures for a custom lightning protection solution include:
With the growing use of wind turbines for power generation, the role of LPS to limit outages and system downtime will become increasingly critical. In addition to designing wind turbines that can handle minimal damage from lightning strikes, it is also important to consider lightning protection design that minimize the time, complexity, and cost of repairs. Reduced probability of damage, combined with cheaper and faster repair mechanisms, is likely to significantly reduce the economic impact of unavoidable lightning strikes.

Lightning protection system - A complete system of strike termination devices, main conductors (which could include conductive structural members), grounding electrodes, interconnecting conductors, surge protective devices and other connectors and fittings required to complete the system.
Terminals / Lightning arrestors - Also known as lightning rods, is installed on roof ridges, dormers, chimneys, ventilators, and or other tall structure to divert lightning harmlessly into the ground. It was invented by Benjamin Franklin in 1749, over 265 years ago.
Lightning protection design - The proprietary and comprehensive plan and/or drawing incorporating a lightning protection system, grounding engineering and surge protection solutions; completed by engineers specific to a facility’s needs. It’s created to protect the facility against lightning strikes and lightning’s secondary effects.
Main conductor - Cables, which interconnect the air terminals to ground
Bonding - An electrical connection between an electrically conductive object and a component of a lightning protection system that is intended to significantly reduce potential differences created by lightning currents.
Bonding connections - these are made to equalize the potential between grounded metal objects bodies or electrically conductive objects and a lightning protection system
Surge protection devices - A device intended for limiting surge voltages on equipment by diverting or limiting surge current that comprises at least one nonlinear component while remaining capable of repeating these functions.
Transient - A subcycle disturbance in the ac waveform that is evidenced by a sharp, brief discontinuity of the waveform.
Ground termination - These are typically copper or copper-clad rods driven into the earth a minimum of 10 feet in depth.
Grounding Electrode – A portion of a lightning protection system, such as a ground rod or ground conductor that is installed for the purpose of allowing lightning current flow into the earth.

Lightning is very damaging and so is the static build up from an electrical charge in the air during a lightning storm. While a direct lightning strike can cause fire or explosion, the static build up can cause a charge to run down the cables and damage connected equipment.
In other words, a lightning strike or static build up wants to get to ground and will follow the path(s) of least resistance to do so.
The grounding rod and the entire grounding system provide a direct least resistant path to ground, rather than into our equipment.
How does a grounding rod reduce resistance?
Chem-Rod – LECs manufactured grounding rod called Chem-Rod® which is an ultra-efficient grounding electrode designed to provide optimal low resistance, low impedance interface with earth. Chem-Rod® achieves its full potential with Grounding Augmentation Fill (GAF) & LECWELD.
GAF - 95% of the resistance of a grounding rod is established by the soil within an area whose radius is 1.1 times the electrodes length. Augmented soil with GAF (a special formulated mixture to help create low resistance earth interface) backfill facilitates a low resistance ground connection. GAF has a low freezing point and expanding factor, and retains moisture better than local soil
LECWELD – it’s engineered to be an easy and efficient field welding system. No outside power, bulky gas tanks or other equipments associated with welding are required. It creates a permanent, homogenous and molecular bond that cannot loosen or corrode. It can also withstand more current that the conductor itself.
Installing a proper grounding rod in accordance to the international grounding techniques not only protects your facility from damaging surges and spikes, but also keeps your facility safe from any ill effects of latent system failure.
We are a full service firm aligned to solve your most complex challenge in grounding. Let us discuss your requirements.
A lightning strike is basically a massive electric spark that’s either travelling between the clouds or from a cloud down to earth. This is an uncontrollable natural phenomenon with an estimated 30 to 50 million volts in each lightning.
Think your business doesn’t need lightning protection? Think again.
200 thunderstorms are happening on earth on any given moment with 100 lightning flashes occurring every second. Maybe you are thinking it doesn’t matter as your facility is not in a lightning prone area. The truth is that lightning doesn’t discriminate; it can strike anywhere on earth.
And when lightning directly strikes a building, it has the potential to damage the structure, critical equipment and also the occupants as it can induce fast transient over voltages into the power system.
Fortunately of all the violent and catastrophic natural calamities, lightning is one of the most simple and economical to be protected against and we are pioneers in innovative lightning protection technology with a ‘no strike’ warranty.
At Lightning Eliminators we offer superior lightning protection system to suit all types of commercial and industrial buildings. Our lightning protection and surge protection solutions are based purely on solid, well-grounded science. We endeavour to supply turnkey solutions, which are both technically and economically effective.
We can protect your facility from a lightning strike in just two steps:
Our lightning protection system does not attract a lightning strike. Rather, it prevents the occurrence of a lightning strike in a safe zone. And in case of a direct lightning strike, if any electrical discharge does get through, our system provides a specified pathway on which lightning can travel and ground itself to earth. This double lightning protection leaves the structure, its occupants, and materials unharmed.
Further, every installation is done with minimum disruptions to your services. All our manufactured and patented lightning protection and surge protection products comply with the appropriate national and international standards. We also extend a ‘no strike’ warranty with all our installation and services.
With the wealth of experience of over 4 decades, LEC is a well-known advisor for an appropriate and cost-effective lightning protection solution to meet your specific need.
The modern industrial business landscape is one that relies heavily on technologically advanced, mission-specific equipment in order to perform critical tasks. These components are crucial to the processes of any number of industries and are also alarmingly sensitive and easily damaged. Though physical barriers against damaging natural elements are nearly always designed in for the systems before they ever are switched on, they can provide nearly no protection against violent electrical storms and lightning strikes, nor the resulting power surges which account for a large percentage of damage to critical components in the field.
Though Lightning protection technologies for power systems have been in use for over 100 years, Lightning Eliminators has developed new ways to mitigate the effects of lightning.
When utilities or power generation facilities experience adverse operational events and are subsequently knocked offline the cost can be devastating, resulting in the ultimate consequence of death, and/or substantial losses and liabilities which can have an impact on customers ranging from thousands of dollars to millions, depending on location and the customers who are impacted.
In order to do this properly, electric power companies should install good quality, certified lightning protection products and implement a full and extensive lightning risk mitigation plan.
Some of our innovative, patented lightning protection products are:
Dissipation Array System (DAS) uses a different, innovative method of operation. DAS uses “charge transfer” technology, which prevents the termination of lightning within the area of desired protection. The technology is so effective, the DAS has over a 99% success rate and is the only lightning protection product to offer a full no-strike warranty.
The Spline Ball Ionizer (SBI) is UL listed and used to supplement DAS, and/or for structures that require lightweight protection with a low wind profile. When used as primary protection the SBI acts as a hybrid ionizer/air terminal, preventing most strikes and collecting any it cannot prevent.
The Spline Ball Terminal (SBT) replaces standard lightning rods in new or existing NFPA 780 or UL 96A installations. Like the SBI, the SBT reduces the risk of direct strikes in its primary mode and acts as a highly efficient air terminal in secondary mode.
For over 43 years, Lightning Eliminators (LEC) has successfully assisted companies across multiple industries and around the world in reducing risk, saving money and increasing reliability.

Lightning strikes are not an uncommon event today and any electronic device that stands in its path would be damaged beyond use. And unfortunately there is no exception for heavy duty IT infrastructure such as data centers.
Protecting your servers and staff from lightning strikes and electrical surges is crucial.
LEC has the experience and equipment to ensure that your data center is safe from the dangers of lightning.
What is a lightning protection design system?
Copper and aluminium conductors are used to outline the structure with lightning rods and are connected to grounding rods around the building. These grounding rods are driven into the ground and joined by a welded or mechanical connection. When lightning strikes, the lightning rod takes a hit first and carries the strike safely to the ground where it dissipates directly into the earth.
Lightning Eliminator’s method
The Dissipation Array lightning protection design system prevents the formation of streamers on ground based objects. LEC's Charge Transfer System (patented as the Dissipation Array System or DAS) uses a naturally occurring, scientific phenomenon called point discharge to retard the collection of lightning within a finite protection zone. LEC does not attract the lightning. LEC's system lowers the static field in the protected area long enough for the lightning strike to terminate outside the protected area. DAS is engineered to the specific application or site.
Of course, our lightning protection design system and proper facility grounding can take away the lightning impact from the spot thereby preventing big damages. But it’s not just the heavy lightning strikes that make your facility vulnerable; it’s the small power surges as well. Thus surge protection is equally important. It delivers the right level of electrical absorption to handle regular spikes and surges.
Keeping data available, safe and uncorrupted is the paramount mission statement of a data center. Lightning and surge events can easily disrupt this essential functionality and create liability issues, corrupt data, or even damage the servers themselves. Installing a lightning protection design system with surge protection device can help to ensure the consistent protection of the facility and its contents.
Lightning protection systems and surge protection minimises the risk of damage from lightning strikes, voltage and power surges by blocking or redirecting unwanted electrical current to earth. The importance of lightning protection systems should not be underestimated – they minimise the cost of replacing electronics and dealing with fire after a sudden severe lightning strike.

Best Warranty and recertification
Yearly recertification is needed to maintain the terms of the no-strike warranty issued with every Dissipation Array System (DAS). This warranty comes for a period of one year and can be extended for additional 12 month periods upon completion of an inspection and any required repairs.
A note on our patented system called DAS – It is the only lightning protection system that can prevent a lightning strike.
This technology retards the collection of lightning within a finite protected zone. In more simple words, the system reduces the potential voltage difference between the protected site and the storm clouds significantly, thus preventing a lightning strike

Do you know the electrical surges generated by lightning produce voltage spikes powerful enough to overload and damage any appliance plugged into an electrical outlet? Lightning-related damage costs billions of dollars.
Apart from lightning strikes, there are other ways electrical surges can occur, such as:
- When utility companies turn on the power supply
- Damaged or downed power lines
- When heavy electrical equipment such as motors, start up
Lightning Surge Protection Devices are devices that are used to protect a system from voltage spikes. It’s an umbrella term that is used to represent any protective device used for overvoltage protection. SPD is designed to limit transient overvoltage and divert current waves to earth, to limit the amplitude of this overvoltage to a value which is not dangerous for the electrical installations and switchgears.
According to the National Electrical Code (NEC), a surge arrester is defined as: "A protective device for limiting surge voltages by discharging or bypassing surge current, and it also prevents the flow of current while remaining capable of repeating these functions".

Lightning strikes are a primary cause of devastating and expensive fires in storage tanks in the petrochemicals sector and throughout the country’s utilities and power generation sectors as well as data centres, telecommunication centres and mass transit and logistics facilities.
To ensure your property is protected from a lightning strike it’s essential to put a Lightning Protection System (LPS) in place.
Lightning protection acts as a safeguard, it’s designed to protect a structure by intercepting extremely high currents of strikes and passing them safely from the structure to the ground. These systems also lessen the fire hazard which lightning strikes can pose to structures.
What are the main components of a lightning protection system?
- Air terminals (lightning rods or strike termination devices)
- Bonding conductors
- Ground terminals (ground or earthing rods, plates, or mesh)
There are four general types of commercially available lightning protection systems, as follows:
- Conventional air terminal systems – designed to collect strikes
- Early streamer emitting air terminal systems– designed to collect strikes
- Charge Transfer Systems – streamer delaying arrays that are designed to prevent all possible lightning strike collection
- Hybrid System - streamer delaying air terminals that collect strikes only when charge transfer capacity is exceeded by dissipation requirements.
There are two parts to a lightning protection plan
