A Proactive 4 Point lightning Protection Design Plan for Telecommunication Industry

Lightning happens! While it can be a spectacular phenomenon to witness, it can also cause damage to property, structures, and even be fatal to human life. Without a doubt, expenses from lightning damage can be substantial—especially for companies whose equipment is installed on tall structures.

LEC engineers can help protect telecom facilities from the dangers associated with lightning strikes using a four point lightning protection design plan.

Step 1

Dissipate the Lightning Strike 

The Dissipation Array System (DAS), generically known as a charge transfer system (CTS), is the only lightning strike prevention system. That is, the system prevents the termination of lightning strikes within any area defined as “protected”. Since the objective of DAS is to prevent lightning strikes to a protected area, the system design accomplishes three sub-objectives. These are (1) preventing any protected site or structure from generating an upward moving leader, (2) delay progress of the descending lightning leaders into the protected area, and (3) suppressing any upward rising streamers from the protected site or structure.

Step 2

Down Conductors 

The function of the down conductor is to collect the charge induced on the area or facility to be protected, conduct the collected charge to the ionizer, providing a low surge impedance path in the process. Finally to transfer the collected charge to the adjacent air molecules via a principle known as “point discharge.” The resulting ions make up what is known as “space charge”, a mixture of charged and uncharged particles. This space charge forms a buffer between the protected site and the storm cell. The result of this buffering effect is a reduction of the electrostatic field at and below the DAS.

Step 3

Grounding system

For telecommunication sites our patented Chem-Rod grounding rod has been proven to be the best grounding (earthing) solution of all the electrodes available. The Chem-rod is so efficient that even one such rod can replace up to ten standard ground rods.
Also available is LECWELD – it’s an easy and efficient field welding system, requiring no outside power source or equipment for lightning safety installations.
Additionally, our Ground Augmentation Fill (GAF) is a specially formulated to help create low resistance earth interface, making lightning protection design plan easier and less expensive.

Step 4

Protect incoming AC and DC power feeders from surges and transients

Grounding controls many safety and noise considerations at a telecommunications facility. However, grounding alone does not fully prevent a transient or surge to the facility from outside. Surge protection devices are needed to mostly alleviate this concern. LEC has UL listed products like Facility Guard, Transient Limiters, DC surge protectors, etc. ​There are also low voltage data lines and telecommunication protection products like TE500, DLP, and CLP.

Lightning is unpredictable. Implementing our proactive 4 Step lightning protection design plan can lessen the risks that lightning pose to your telecommunications facility.

Chem Grounding Rod – The Earth Electrode Your Facility Requires!

The chance that your facility will be hit by lightning varies on a number of factors such as location, structure height, temperature, and humidity.

Lightning is nature’s attempt to equalize the voltage between storm clouds and the earth. In order for lightning to strike, it must connect to upward streamers, which reach up from earth-bound objects when the electrical field is strong enough. DAS, our patented lightning protection system, interrupts the formation of these upward streamers through point discharge, a phenomenon where a well-grounded point exchanges ions between the air and the ground. Point discharge becomes more efficient when the points are connected to a low-impedance grounding system, and more ions can be transferred with a greater number of points.

Proper grounding is critical to personnel safety and uninterrupted operations, and serves as the foundation for complete lightning protection systems.

Grounding rod is a type of earth electrode.

An earth electrode is a conducting element buried directly in the ground, facilitating the flow of fault currents towards the ground. This means that earth electrodes are metallic and, since they have to be buried for long periods of time, they need to be resistant to corrosion as well. Earth electrodes can come in a variety of materials, shapes, sizes, and arrangements including pipes, plates, a ring around the structure (known as Type B Earthing), or as an Earth Rod (grounding rod).

Outperforming competition, our ultra-efficient Chem-Rod (LEC’s manufactured and patented grounding rod) has been used to replace as many as 10 conventional rods.

Chem-Rod Grounding Electrode: The patented Chem-Rod creates the optimal earth connection with a large conductive surface, electrolytic salts, and specially formulated backfill. Available in a variety of configurations, Chem-Rods help achieve your target resistance using fewer electrodes and less real estate.

In addition to our specialised products and services, we offer standard ground testing services, as well as, a full line of ground resistance meters and grounding components available for purchase.

A special mention:

Smart Ground Testing: It’s an advanced ground audit system that produces highly accurate results, even on energized systems. Unlike traditional tests, smart ground utilizes sophisticated computer modelling, includes a complete professional analysis to IEEE/IEC standards, and provides practical recommendations to improve your grounding system.

Many industries are benefitting from our Chem grounding rods. We are a full service firm aligned to solve your most complex challenges in lightning protection, grounding, and surge suppression.

What is the Simplest Method to Prevent Lightning Damage?

How can you stop lightning damage? The fact is, you can’t actually stop lightning, but you can redirect it. This we have discussed in our other blogs. Today we are here to tell you the different type of damage, how to identify them and protect your facility, personnel and other assets.

A lightning strike can cause significant structural damage to a building. It can lead to damaged machinery and equipment, both inside and outside the building and may result in harm to people.

There are four basic types of lightning damage: physical damage, secondary effect damage, electromagnetic effect damage, and damage caused by changes in ground reference potential.

Ground reference potential

The lightning current that falls on a lightning conductor causes an increase in the earth potential of an installation, which will cause an overvoltage between the earthing system and the internal lines within the installation. This overvoltage spreads to neighbouring installations via the distribution network. When a lightning strike hits the ground or an item near the building (prominence, tree, post, etc.) directly, there is a similar increase in the earth potential causing over voltages in installations near the strike, via their earthing electrodes.

Lightning damage by electromagnetic effect

The lightning discharge current, whether by direct strike or carried by a lightning down conductor, generates a field whose electrical and magnetic components reach considerable voltage. This electromagnetic field can induce electrical currents in nearby conductors, including wires and electrical equipment. The current induced by electromagnetic effect can easily be sufficient to cause damage.

Secondary effect damage

Indirect effects can also be damaging. For example if lightning strikes a building transient, over voltages maybe caused through resistive, inductive and capacitive coupling. If it takes place:

  • Within a flammable material, it can cause a fire or explosion.
  • Within a bearing, such as in a pump in a treatment plant, it can scar the bearing and cause premature wear.
  • On a circuit board, it can damage the circuit board.

Here are some things that can be done to minimize lightning damage

One of the simplest methods to prevent lightning damage is to install a lightning protection system.

Lightning will strike whatever it desires, buildings, trees, mountains, cars, etc. so it’s important to be aware of both direct and indirect lightning strikes and the damages that they can create.

Lightning Protection Products using Charge Transfer Technology

Protecting a premise against direct lightning strikes by preventing lightning stroke is not exactly a new idea. It was Franklin’s original idea that he could dissipate the thundercloud electricity by installing the pointed iron rod, which would quietly conduct the electricity away.

In recent decades, due to the explosive progress in computers/electronics technology, the secondary effect of the lightning stroke became the major concern. Generated by lightning current, the strong magnetic field around the downward conductor connecting the lightning rod to the grounding system caused the induced voltages of such a magnitude that it permanently damaged or caused malfunction of sensitive electronic equipment located nearby. The prevention of the direct lightning strokes into the premise is one of the ways to eliminate the damaging consequences of the secondary effect.

Lightning Protection

Thus the idea of preventing the lightning stroke based on point discharge phenomenon took place and research and development started at Lightning Eliminators & Consultant, Inc.

Today we have patented lightning protection products that meet the requirements of National Fire Protection Association NFPA 780 and are Underwriters Laboratories Listed.

Lightning Protection

Let us discuss some LEC’s lightning protection products that functions as CTC

Dissipation Array System (DAS); is the name for our patented Charge Transfer Solution (CTS). The DAS is designed with a combination of different multipoint ionizers to function in the Prevention Mode. Point discharge becomes more efficient when the points are connected to a low-impedance grounding system, and more ions can be transferred with a greater number of points. DAS technology takes advantage of these principles with an optimal point configuration able to interrupt the formation of upward streamers, thereby preventing direct strikes.

Spline Ball Ionizer (SBI) is a modular lightning prevention component used to supplement Dissipation Array installations, and as the first line of defence for structures that require lightweight protection with a low wind profile. They are a multipoint ionizer that can be deployed along with DAS to function in the Prevention Mode or multiple units of SBIs can be deployed without DAS to function in the CTS Collection Mode. SBI's are normally mounted in groups on elevated structures.

Spline Ball Terminal (SBT); is a single multipoint ionizer in the Charge Transfer System (CTS) family. Because it is designed with a limited number of ionizing points on the unit, it falls into the collection of CTS operation.

Ion Plasma Generators (IPG); is a multipoint ionizer that functions only in the Collection Mode. Our patented IPG is a highly effective air terminal engineered for applications where lightning prevention is not practical, but that still require reliable protection from direct strikes.

The best defence against lightning damage is now simple, reliable and inexpensive lightning protection product brought to you by LEC.

Advantages Of A Chemical Grounding Rod

An efficient grounding system is critical to personnel safety and uninterrupted operations but conventional ground rods are typically insufficient for industrial uses where target resistance can be less than 1 ohm.

The Chem-Rod solves problems found with conventional ground rods by requiring less real estate and fewer electrodes to meet specified resistance.

Do you know the advantages of installing Chem grounding rod manufactured by LEC?

  • Large surface area: The wider 25/8 inch diameter provides a larger surface area for a better connection to the earth.
  • Electrolytic salts: In the presence of moisture, these salts dissolve and seep out of leach holes along the electrode. The salts continually increase the soil’s conductivity, further reducing impedance and resistance.
  • Soil augmentation: Ground Augmentation Fill (GAF) is a combination of organic soil materials which optimize the conductivity of the soil around the Chem-Rod. Increasing the amount of GAF can decrease the overall system resistance, increasing the system efficiency.
  • Easy refills: Every Chem-Rod comes with a standard removable cap and access cover for easy maintenance of the ground salt charge.
  • Optimized pigtail: The 2-foot long, 4/0 AWG stranded pigtail is exothermically welded to the body of the Chem grounding rod.
  • Improved Safety: The Chem-Rod can reduce these risks more effectively than other ground rods by providing the most efficient earth interface. In addition, it meets or exceeds relevant design codes and safety standards for protection of personnel, property, and sensitive equipment.
  • Outperforming competition: A recent NEGRP study tested 15 different types of grounding electrodes including the horizontal Chem-Rod and vertical Chem-Rod. The test included 8 years of analysis at five U.S. sites with results verifying that the Chem-Rod consistently provided the lowest resistance of all models tested.

How does a grounding system work?

Complete grounding system carries unexpected electrical charges safely to the ground without harming any other source. For example, a lightning strike can easily send an extra voltage of electricity to different electrical components thereby damaging them. With a grounding system in place, this damage can be easily avoided.

Efficient grounding systems reduce the risk of electrical arcing and fires. The chemical grounding rod by LEC improves reliability for many applications, including:

  • Lightning Protection System
  • Prevention of accidents caused by static charge and stray currents
  • Protection of central communications, electronics, and AC power systems
  • Meeting grounding safety requirements for electrical substations
  • Ground fault neutralization
  • Safeguarding critical instrumentation and process-control equipment

Our grounding rod has proven to be the best and most economical grounding solution.

Grounding Rod Lightning Protection – Tailored Solution by LEC

A grounding rod acts as the only electrical path to dissipate static discharge voltage, occurring due to switch load or natural circumstances, such as lightning, into the Earth. And when this path starts to break down, the static discharge has nowhere to go, putting the whole facility at risk.

A well-designed grounding or earthing system is essential for any electrical installation to avoid dangers associated with transient or overvoltage. Good earthing protects both equipment and people against the dangerous step and touch voltage. A good grounding rod:

  • Provides security to people by limiting the overvoltage
  • Protects the assets of a company by providing a low impedance path for the static electricity to pass
  • Minimizes the electromagnetic noise

Being a leader in the field of lightning protection systems, Lightning Eliminators and Consultant Inc. has spent many years developing and testing superior lightning protection products.

Such as our patented Chem-rod

  • Efficient – these rods reduce risk more efficiently than other grounding rods by providing the most efficient earth interface.
  • Consistent performance – they are highly resistant to corrosion, making them more dependable and giving them a longer service life
  • Economical – using Chem-Rods instead of traditional grounding rods lowers overall costs and improves protection. This is because one Chem-Rod can replace as many as 10 conventional grounding rods. Secondly, it has four times more surface area as compared to their traditional counterparts, helping Chem-rods to create the low-impedance connection required to safely channel high-frequency lightning currents to earth.
  • Low maintenance – it is designed for easy inspection and refill. They come with a standard removable cap and access cover for ease of maintenance of the ground salt charge.

No doubt grounding systems should be checked periodically, as per recommendations; our Chem grounding rod is readily accessible for inspection convenience. The readings - resistance of the system, conductive salt levels, variation in moisture, atmosphere and groundwater movement, are all recorded and stored for future reference.

LEC technologies have proven to be more than 99.87% effective in eliminating all strikes to the protected areas. Minimize one significant threat from your list of concerns by assessing lightning exposure and taking action.

The Only Lightning Protection System With A No-Strike Warranty

The forces associated with lightning are enormous and unpredictable. Controlling and directing the energy of lightning to protect humans, buildings, and equipment is a concern.

For over two centuries, the lightning rod has served as the primary means of protecting assets from lightning after Benjamin Franklin invented it as a solution to preventing house fires in the 18th century. Lightning became more of a threat as the heights of buildings rose. However, attracting lightning is not something that owners of multi-billion dollar oil and gas facilities want. Instead, LEC uses charge transfer technology to prevent direct strikes by lightning to protect energy assets, whose electronic components can be knocked out by lightning in the blink of an eye.

Protection against lightning involves three parts – direct lightning protection, surge protection and grounding.

Direct Lightning protection

LEC’s Dissipation Array System (DAS), based on Charge transfer technology – is intended to prevent a direct lightning strike from occurring within a protected zone or area.

The charges transferred to the air can act in one of two modes – collection, which establishes a preferred conductive path for the lightning leader, and prevention mode, which reduces the electric field intensity to the level that delays the formation of an upward streamer from the protected area.

LEC prides itself on being able to provide consulting, design and implementation services for lightning protection. Our technology has been used to protect assets in the upstream and downstream oil and gas industry, as well as across multiple industries – petrochemical, power generation, biochemical, chemical manufacturing, information technologies, nuclear energy, mining, utilities, and manufacturing.

The company offers custom solutions, based on a clients' need and risk tolerance, as lightning protection involves more than a cookie cutter approach. Maximum ionization is achieved through point spacing, length and the number and geometry of points.

Additionally the confidence in our product prompted us to extend a full no-strike warranty to each and every client who buys a system and recertifies it each year!

Welcome to Lightning Eliminators & Consultant Inc. A place that helps you protect your assets by eliminating lightning!

Which is the best lightning protection system for your facility?

The successful 200-year-old method of using a (Franklin) rod to collect, control, and convey to earth the awesome and destructive power of lightning has produced other alternative methods.

To properly select a lightning protection systems to protect buildings and structure from lightning damage, one needs to know the types of interaction that occur between clouds and earth.

As a thunderstorm builds, a break down point is reached and the cloud begins sending down charges called ‘stepped leaders’ through ionized paths in the atmosphere. Multiple stepped leaders begin propagating towards the ground in three dimensions looking for the highest accumulation of ground charges in the area. The charges move in steps of approximately 50 meters, stop & look for the best potential, then move again. These steps & redirections give lightning its appearance.

Which is the best lightning protection system for your facility?

LEC’s lightning protection system is based on Charge Dissipation Principle. This technology uses the point discharge principle to facilitate the dissipation, or the reduction, of a buildup of static electrical charges.

The sole purpose of Dissipation Array System, our patented product, is to reduce the accumulation of electrical charges and thereby prevent an electrical arc or an electrical current flow through the area of protection that can cause damage.

How does DAS work?

When a pointed grounded conductor is placed in a high electric field (such as on a structure located in a thunderstorm) voltage effects at the point are increased greatly. Electron from the atmospheric atoms and molecules are stripped away and flow to ground through the grounded conductor leaving behind positive atmospheric ions around the point. This process is referred to as the ‘CORONA EFFECT”.

This corona effect begins long before charge accumulation reaches a critical level when step leaders begin forming in the storm cloud. The result is an accumulation of ions around the point which disperse/dissipate in all directions away from the point. Electrons left behind from this dissipation of ions flow to ground and neutralize the positive charges accumulated on the ground and on the structure. This is an ongoing process as the thunderstorm builds and passes over the facility.

DAS lightning protection system was introduced in 1971. Since that time, over 3,000 systems have been installed worldwide, accruing over 40,000 system years. Throughout this time, the DAS has maintained a success rate over 99%.

Data Center Lightning Protection Design Systems

Data Center - A boon in improved communication, data storage, and business efficiency. But, it has also introduced a new area of vulnerability. There are potentially expensive concerns to consider where it relates to lightning strikes. The equipment and infrastructure in such a facility, which includes delicate and costly state-of-the-art hardware, internal circuitry and other system architecture, is susceptible to more than simply being taken off-line in the short term.

A good lightning protection design must consider these 6 interdependent protection points:

1. Capture the lightning strike. 

2. Convey the energy to ground. 

3. Dissipate the energy into the grounding system. 

4. Bond all ground points together to create a single point ground plane. 

5. Protect incoming AC feeders. 

6. Protect low-voltage data/telecommunication circuits.  

A tremendous amount of damage can be done if you do not consider all the areas that need protection; lightning strike protection, proper grounding with appropriate surge protection.

Lightning protection design by LEC

There is an assertion that it is nearly impossible to protect completely against lightning strikes is commonly taken as fact, but lightning strikes are currently being prevented in areas of concern at countless locations in more than 70 countries thanks to the solutions provided by Lightning Eliminators & Consultants.

Our 40-year-old technology has enjoyed a 99.87% success rate with eliminating direct strikes at the sites we protect. Rather than collecting lightning and directing it to the ground, as a traditional lightning rod does, our design and protection systems prevent the formation of lightning within a protected area.

In addition, our lightning protection design includes a surge protection system design:

Lightning can infiltrate your power infrastructure and sensitive electromechanical systems in many ways. Direct lightning strikes to your facility or assets pose an obvious hazard, but nearby strikes can be equally damaging, particularly if lightning signals are strongly coupled into power and other utilities that enter your facilities. The function of a surge protection device is to sense and limit the transient over voltages to levels which the connected equipment can withstand safely.

Nothing beats the expertise of an experienced professional to design and specify a protection system to ensure the safety of the building and everything in it, including personnel.  

Lightning Eliminators can provide the needed design and installation requirements in order to keep your facility safe from direct lightning strikes as well as stray transient voltages from both, above and below your facility.
