Everything You Need To Know About The Perfect Grounding Rod

A grounding system’s job is to connect the electrical system of a facility to the ground underneath. It helps carry unexpected electrical charges safely to the ground without harming any other source. For example, grounding system limits the potentials of lightning to create havoc on the property, electrical equipment, and human life.

A grounding rod is an essential part of every ground and electrical system, connected to the physical earth, diminishing the powers of lightning.

Why do we need a grounding rod?

By installing a grounding rod you know that it will protect people from electrical shock, help safeguard expensive electronic equipment, limit neutral to ground voltage and satisfy NEC regulations along the way.

However installing a conventional system requires more real estate and electrodes to meet the required resistance.

LEC’s patented Chem-Rod Grounding Electrode is the latest electrode used worldwide. It provides a low surge impedance as well as low resistance earth contact. The ground augmentation fill is the key component that makes this Chem-Rod maintenance free, giving a longer performance, and ensuring best grounding connection possible.  It has a large conductive surface but takes up far less land mass and can easily replace multiple conventional grounding rods.

They are most useful in areas with limited earth for grounding and are very cost effective for reaching target resistance. Chem-Rod by LEC has been solving problems posed by conventional grounding rods for over 30 years.

Soil PH is another important criterion to be considered. A soil PH at par or below 4 is particularly harmful. Being highly acidic in nature it can reduce the life reliability of the entire grounding system. A well-aerated soil with neutral PH is likely to cause limited corrosion of the grounding rod electrode.

Check out the Smart Ground Testing services from Lightning Eliminators & Consultants, Inc. The results of the ground audit are highly accurate and the engineers give a very practical solution to improve the grounding system.

LEC enjoys a worldwide reputation as a foremost specialist in lightning protection products and services, and we have also proven our commitment to research and development. We are devoted to offering a truly effective system and design, providing the highest level of safety and effectiveness in grounding rod.  

No. 1 Fuel Tank Lightning Protection Solution

Lightning strikes are far more common than many realise and with the changes in the global climate and changing weather patterns, they are well and truly on the increase. 

Petrochemical storage tanks at Oil & Gas Production and Disposal facilities are particularly susceptible to lightning strikes and/or build-up of static electricity. Given the often natural volatility of the contents in fuel tanks within these facilities, a subsequent explosion and fire caused by lightning or static build-up can have absolutely catastrophic effects. 

Do you know, about a third of all tank fires are believed to have been started by a lightning strike which makes fuel tank lightning protection system a necessity.

Challenge

There are 15 to 20 tank fires per year, and over half of them involve Floating Roof Tanks. These fuel tanks require protection against being ignited by a direct or nearby lightning strike. Lightning strike causes electrical currents to flow across the tank shell and roof. When these lightning currents arc across the roof/shell interface, they can ignite any flammable vapours that may be present. It’s therefore necessary to bond the roof and shell to prevent arcing at the roof-shell interface.

Earlier chemical manufacturers and oil and gas exploration and production companies had been using metal strips called “shunts” that electrically bond the shell and roof of the tank in multiple locations. Unfortunately, the bond that these shunts establish is unreliable and creates a greater risk of sustained arcs.

Solution

Substantially reducing the risk of sustained arcs requires a reliable, full-time, low impedance and low resistance connection between the tank shell and roof. Additionally, the connection must operate regardless of the tank wall’s condition.

The RGA (Retractable Grounding Assembly) grounding/earthing equipment for lightning protection is not affected by the condition of the tank because the RGA and cable are bolted and sealed to optimal locations on the tank shell and floating roof

This equipment is designed and manufactured by our expert LEC team in Colorado for fuel tank lightning protection and has proven its reliability and effectiveness with more than 3,000 successfully operating installations around the world.  

RGA is a retractable conductor wound onto a spring-loaded reel – which is mounted directly on the tank wall or a suitably positioned mounting bracket – that is designed to electrically bond the floating roof and shell on floating roof storage tanks.

Our RGA fuel tank lightning protection solution can be installed in both new-build or retro-fitted to existing tanks and requires little regular testing, inspection or maintenance other than visual inspection of all moving parts, the removal of dirt and debris, lubrication of the bearings, and the tightening of all mechanical fixings.

Commercial Lightning Protection for Railways

Lightning is a natural phenomenon that can have a significant impact on railway facilities. Electricity is a major part of railway system operations and the multitude of parts and components it takes to build the railroads across the world are numerous.

A train is a metallic structure, equivalent to a conductive mesh, and therefore a direct lightning strike does not cause damages to the vehicle structure.

However, this does not avoid the direct strike and overvoltage to the electric lines – the overhead traction structure literally forms a huge lightning antenna, which if struck by lightning can damage or even disable the internal equipment, stopping the train and disabling communications. That’s why lightning protection of railway facilities is a vital part of its safe, reliable operations.

As the electrical and electronic equipment in the railway industry has become more complex and integral to the modern design and operation, protection against lightning strikes becomes ever more critical. 

Many complications can arise from a lightning strike, such as:

  1. Safety risks to personnel
  2. Damage to critical equipment
  3. Data corruption
  4. Operational downtime

To protect your railways from the dangers of a direct lightning strike, LEC offers patented lightning elimination product called the Dissipation Array System (DAS).

Unlike lightning rod systems, our DAS completely isolates facilities from a direct lightning strike by bleeding off the induced charge on the protected area during the course of a thunderstorm, reducing it to a much lower level in relationship to the surrounding environment. This suppresses the formation of an upward rising streamer, one of the required elements of the strike process, thus avoiding the strike. It is the only such system where the lightning impulse is not encouraged, but discouraged. In fact, DAS technology has proven to be more than 99.87% effective in eliminating all strikes to protected areas.

In addition to the increased uptime, your railway system will achieve a significant savings in repair costs.

To conclude, Lightning is always a threat to facilities with critical operations and businesses, not limited to only the railway system. Any traffic system that depends on smooth operations and minimal downtime needs to get their facilities well-protected from any unforeseen weather conditions. With our lightning protection solutions (including the DAS technology), we are very keen to contribute and ensure business continuity for our customers.

Lightning Protection System – not an Artefact, but a Necessity

While lightning rods are often seen as an artefact, a lightning protection system is a necessity for every business.

Your business faces many risks if you have not installed a lightning protection system on your premises. If lightning strikes a business without a clear path to ground, the current can cause serious damage both to the building structure and its electrical components. It can even start a fire.

Specifically a lightning strike can:

  1. Start a fire outbreak – as lightning heats up the air around it, the furniture and cabinets can easily ignite. Also lightning can cause an electrical malfunction which can trigger an electrical fire
  2. Fry electrical wiring – an electricity overload can heat up conductors and damage insulations. While some electricity may be forced to flow through unintended paths causing further damage.
  3. Damage electrical and electronic assets – just like electrical wiring, the electricity may overload plugged electrical and electronic assets damaging them too
  4. Injure your employees – your employees can be seriously injured if you don’t have lightning protection system installed on your premises. They can get trampled in a stampede after a lightning strike, get injured by malfunctioning appliances, or suffer burns by lightning induced fires.
  5. Trigger liability claims – a lightning strike can trigger liability claims by a client who did not receive your service because your business suffered from a lightning strike, or a lightning strike injured your client who was on the premise at that time
  6. Uncomfortable working environment – a lightning strike can knock off the premise cooling or heating system and even damage the plumbing system, thus making the working environment very uncomfortable

The good news is that you don’t have to expose your business to these risks. With Lightning Eliminator’s lightning protection system in place you need not worry about lightning strikes.

We offer complete, integrated lightning protection solutions to every industry through our patented Dissipation Array System.

This system can prevent or eliminate a lightning strike. As a storm approaches, a high voltage electric field is built up. Our system slowly dissipates this energy by ionising the air molecules above it thus the voltage needed for lightning is never attained.

Prevent Lightning Damage to Your Power Plant and Keep Powering Society

From operating house hold appliances to connecting global business, electricity is pivotal to modern society. Large power plants have been built to supply energy and they are often required to operate round the clock to fulfil energy demands.

Power generation plants face many challenges to meet the power demands of a growing and urbanising population. The challenges posed by lightning have proven to be especially trying. This unplanned event can damage facilities and equipment, disrupt work and even cause injury or death. A prolonged service outage from lightning strike can cost the plant thousands of dollars from lost revenue and the cost of repairs.

Safeguard your power plant assets from lightning damage just like Brown Ferry’s nuclear plant – due to frequent and intense storms, the challenges posed by lightning strikes to their off-gas stack were hampering reliability of service. Lightning damage had become a routine.

Take another example of the Auburndale Power Partners 150 MW cogeneration plant. With up to six lightning related outages per year, the plant’s sensitive control equipments invariably suffered lightning damage and cost the plant up to $25,000 from lost revenue.

Both power plants decided to install the LEC Dissipation Array System – our innovative, patented and lightning protection system. Unlike lightning rods, which attract lightning, the DAS system is designed to prevent lightning related damage.

After implementing the lightning prevention system, reduced lightning strikes have saved the plants thousands of dollars and the cost savings experienced in the first year of operations have paid for the systems.

Due to the ever changing climate and rising temperature lightning strikes are becoming more and more frequent. The risk is nearly universal: lightning does not discriminate, nor can it be accurately predicted to a great degree of certainty.

The best way to minimize lightning damage and its impact is to be prepared. A growing number of power generating utilities have successfully reduced cost and lowered liability by choosing an engineered lightning protection system to avoid lightning damage. LEC’s charge transfer device, the Dissipation Array System is custom engineered to interface with almost any structure.

Prevent lightning damage from negatively impacting your power generation capabilities with help from Lightning Eliminators. We have you covered.

Making Data Centers More Reliable with Our Grounding Rod

Data centers need to achieve unprecedented level of uptime to keep pace with modern business demands. To achieve this goal, data centers need to pay increased attention to facility infrastructure issues, including grounding systems.

A grounding system is not just an insurance policy against lightning strike. It’s an active, functioning system that provides protections to personnel and equipment and is essential for efficient network performance.

A properly designed grounding system is one that is intentional, visually verifiable, adequately sized to handle unexpected currents safely, and one that directs potentially damaging currents away from sensitive communication equipments.

Most professionals don’t realise the communication industry have some very unique and specific requirements for grounding, grounding rod and bonding. While there are similarities, what is fine in one field doesn’t always do the job in another.

As an expert in lightning elimination, let us explain the many effects of improper grounding.

  • When a surge form direct or indirect lightning or transient, is not properly dissipated by the grounding system, electrical noise is introduced. This causes faulty data signals, decreasing the overall efficiency of your network.
  • According to many surveys, improper grounding rod leads to millions of dollars per year of damage to property and equipment due to lightning.
  • International agencies state that grounding is the most important factor for a reliable network performance
  • Personal injury from electrical shock caused by improper grounding can cause immeasurable human suffering  and significant expense
  • Potential fire hazards exist when heat is generated from electrical surges that find a high resistance path to ground

As more services move to the cloud and devises join the network, the risk of damaging surge migration to other parts of a facility increases. When all devices are networked across systems, a surge could move from a surveillance camera, for example through a digital network of a device on another system. Putting proper grounding, grounding rod and bonding in place can help prevent surges and lightning strikes from spreading across a network and damaging or destroying multiple devices or systems.

From the award winning Dissipation Array System to the patented Chem-Rod, LEC offers the best of products along with a full line of SMART ground testing services and more, ensuring a solution tailored just for your needs.

Contact us and transform your data centre’s grounding system into a high performance ground.

Lightning Safety Tips That Every Employer Should Know

With the changing weather pattern worldwide, the monsoon rains in many regions too have changed, with lightning and thunder often accompanying them. Unlike in the recent past when the rains often just fell silently.

Lightning is one of the leading causes of injury and death from weather-related hazards. While most lightning victims survive, the effects of a lightning strike can be lifelong.

Some lightning safety tips:

  • Plan your evacuation and safety measures in advance
  • When thunder roars, go indoors
  • No place outdoors is safe during a thunderstorm; seek shelter in a sturdy building or a hard-topped vehicle with the windows rolled up.
  • As a last resort, find a low spot or depression and crouch down as low as possible, but don't lie down on the ground.
  • Avoid proximity to other people. If you can, stay at least 15 feet apart from other people.
  • Once inside, avoid using landline phones, televisions, and other appliances that conduct electricity and stay away from water bodies.
  • After it’s over stay inside for 30 minutes after you last see lightning or hear thunder.
  • If a co-worker gets struck by lightning, administer first aid immediately and seek medical assistance. It is entirely safe to touch them.
  • Know your emergency telephone numbers. 
  • Seek customized lightning safety solutions from Lightning Eliminators and Consultants Inc.

A Systematic Approach towards Lightning Protection

Due to the changing weather phenomenon, the number of lightning strikes has significantly increased.  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 – A reasonable response. Once the plant is operational, the question of how to protect the plant against the next lightning strike comes.

With our 4 decades of experience we know that inevitably an ad hoc approach is taken. This results in installing a lightning protection system that does nothing new to protect the equipment that was originally damaged.

The best way forward is a systematic approach – applying to national and international standards, carrying out risk assessment and then acting upon its results to find a cost effective yet successful solutions.

A SYSTEMATIC APPROACH

  1. Risk Assessment

This study considers the following criteria to decide the probability of a lightning strike on that building and its consequent effects:

  • Use of structure (factory, school, hospital, etc)
  • Type of construction
  • Material / process vulnerable to fire
  • Degree of isolation of the building from nearby structures
  • Location of building – this decides the lightning strike density (number of thunderstorms/km3/year)
  1. Acting upon results

Lightning protection is required almost everywhere! Virtually all populated regions have varying incidences of lightning strikes. There is meaningful risk worldwide, also it minimize exposure to serious risk such as:

  • A fire outbreak
  • Fried electrical wiring
  • Damage to electronics and electrical items
  • Injured employees
  • Liability claims
  • Risky working environment

A Lightning protection system helps in preventing property damage from the effects of a lightning strike. It provides a means for controlling and preventing damages by providing a low resistance path for the discharge of lightning energy.

We, Lightning Eliminators, are a professional company that engineers, produces and distributes technology which provides reliable lightning protection solutions. We have successfully completed many projects using our patented products, in various industries, such as:

  • Towers and remote radio architectures in support of  of 4G and 5G networks, microwaves and others.
  • Electric supply lines wherein our patented LPS are deployed along multiple points to mitigate the risk of equipment damage due to lightning.

We have 14 US patents and have been successfully delivering lightning protection system product, design, installation and maintenance in the US and over 90 countries.

Number 1 Reason Why Yearly Maintenance of Lightning Protection Design System is Important

It’s important to ensure that your facility’s lightning protection design system is in good condition and in proper working order. This means having regular maintenance and repair to help determine and identify potential problems. If these systems aren’t working as they should, they could cause hazards to health and safety for all occupants within the facility. A regular lightning protection, inspection and maintenance can help determine and identify potential threats or problems – 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 LPS is located.

Investing in a regular maintenance program can help maintain compliance with regulations, prevent untimely plant shutdowns, and help save money by addressing issues before they turn into expensive unplanned repairs.

Our services:

  • LEC’s fleet of inspection and testing engineers are fully competent in undertaking the detailed inspection and testing of all lightning protection design systems. We recommend yearly inspections, to take account of seasonal variations, ensuring that the entire system is effective at all times.
  • We also provide certificates of inspection detailing our findings, plus details of any repairs required to return systems to a serviceable condition.
  • All our repairs and maintenance works are carried out by our own expert engineers working to agreed methods and time scales; ensuring remedial work does not affect your staff or on-site operations
  • Upon completion of repairs and maintenance, your installation is fully re-tested. Certificates are then issued, detailing the test results and confirming the system's compliance to relevant standards.

Scope of inspection:

  • Visual Inspection of all materials used to conduct current
  • Inspection of lightning rod to ensure none are bent, cracked, broken or otherwise damaged.
  • Refastening and tightening of components and conductors where required.
  • Check for loose, damaged or cut cable connections
  • Continuity tests and measurement of system resistance and grounding electrodes

A special note:

LEC provides the only ‘No Strike’ Warranty in the industry on our DAS solutions. When installed, maintained and supervised by LEC, our DAS prevents direct strikes with a 99% success rate, minimizing the risks to facilities and operations. The benefits can be substantial, resulting in a healthier bottom line and increasing reliability and safety. However like every other lightning protection design product this too requires yearly maintenance.

Lightning Protection Design Systems

Lightning is the natural electric discharge of static electricity in the atmosphere between clouds or between a cloud and the Earth.

Underwriters’ Laboratories Inc. states: “Each year, thousands of homes and other properties are damaged or destroyed by lightning… Lightning is responsible for more deaths and property loss than tornadoes, hurricanes and floods combined, but of these violent forces of nature, lightning is the only one we can economically afford to protect ourselves against.”

Frequent lightning events interrupt, degrade and destroy critical technology, life safety equipment and other essential systems in commercial settings. Full recovery can entail untold time lost and tens, even hundreds of thousands of dollars expended. In worst cases, losses are irreplaceable. Professional lightning protection design system from Lightning Eliminators solves your lightning problems.

Traditional lightning protection design system principles consist in creating one or more preferred impact points for a lightning strike using low impedance, conductor elements. These then conduct and convey the lightning current into the ground. This coherent system enables the lightning to be captured and dissipated while providing protection to the structure. 

Our  patented and innovative Dissipation Array System is designed to delay streamers as compared to an air terminal. As a lightning downward leader is initiated and the electromagnetic field builds up, a static charge accumulation is experienced on the facility and on the lightning terminals installed on the facility. The lightning terminals react by generating upward streamers having the capability to intercept the downward leaders. DAS are manufactured using stainless steel ionization brushes that neutralize build-up of static charges and thus mitigate or delay streamer formation. These are the latest design in lightning dissipation technology. Science and experience show that DAS, and the structures on which they are installed, are less likely to experience a direct lightning strike than unprotected structures or structures with traditional lightning protection design system.

Look no further than our project to understand the trust placed in our professionals. Every project we facilitate is inspected and certified for quality and sustainability by trusted third-party validators.

Few commercial structures exist that are not driven in part, or significantly, by technology. Professional lightning protection design systems act as over watch, protecting the critical systems of the building and its tenants from disruption, or worse.
