Lightning Protection Systems

A lightning rod is connected via a low-resistance wire or cable to the earth or water below, where the charge may be safely dissipated.  As a storm intensifies, it gets electrically charged; a lightning strike occurs when this cloud neutralizes itself with the ground. Any structure that sits between the cloud and ground gets charged and is damaged in the process. Thus a lightning rod protection is installed on the roof of buildings for protection. Lightning can " jump around " when it strikes. This "jumping" is associated with the electrical potential of the strike target with respect to the earth's potential. The lightning can strike and then "seek" a path of least resistance by jumping around to nearby objects that provide a better path to ground. If the strike occurs near the lightning rod protection system, the system will have a very low-resistance path and can then receive a "jump," diverting the strike current to ground before it ...

Franklin’s lightning rods have been used as a means of collecting and controlling the awesome and destructive power of lightning. But is it wise to allow thousands of amperes to flow near sensitive electronic equipment, especially when charge transfer systems (CTSs) are available and can prevent strikes in protected areas? With businesses around the world installing 500 such systems per year, it's a concept worth investigating. In 1971, Roy B. Carpenter Jr. came across the CTS technology while working for the United States Air Force. Carpenter was a chief engineer for the first space shuttle design team. After leaving the USAF, he expanded and patented CTS into the dissipation array system (DAS). It wasn't until the early 1990s that the theory behind DAS advanced and developed into the CTSs available today. Let us look at some of the lightning protection products available with CTS technology: The Dissipation Array System (DAS) is one of the most common configurations of a Cha...

Power generation transmission and distribution, fossil, solar, water treatment plants, substations and nuclear plants are typically constructed in large and unobstructed locations, making these systems susceptible to lightning strikes. Power Generation, Transmission And Distribution  Large power plants have been built to supply energy. Lightning events can damage facilities and equipment, disrupt work, and even cause injury or death to process-critical employees. A prolonged service outage from lightning strikes can negatively impact the community that a power generation facility is designed to serve. Fossil Fuel  Lightning strikes on fossil fuel facilities, refineries, tank farms and their upstream and downstream supply chains can be explosive and deadly.  Lightning protection for these facilities is mandatory.  Lightning strikes can be prevented around the most vulnerable areas and all areas can be protected with proper LP solutions. Solar  Solar farms are ju...

While lightning may seem rare, USA alone receives an average of over 2.2 million flashes to ground each year, and a single bolt of lightning has enough power to peak at 100 million volts of electricity. That much electricity surging through an office or industrial plant at once can be catastrophic for electrical systems and permanently destroy your most expensive electronics. Security for today’s commercial & industrial properties Schools, hospitals, airports, factories, chemical plants, power generating plants and office buildings are just some of the facilities choosing to play it safe against destructive forces of lightning by installing lightning protection systems. Like fire alarms, sprinklers and security systems, a lightning protection system provides the peace of mind that comes from knowing that a potentially catastrophic problem has been dealt with proactively. A properly installed lightning protection system safe-guards a business structurally and also protects property,...

Lightning is a natural phenomenon that can have a significant impact on environment, production and people interacting with thermal petrochemical industries. Thermal petrochemical plants and their storage facilities are uniquely vulnerable to lightning due to the facility designs and the often explosive and caustic nature of the raw materials being processed, handled, and transported.  Lightning strikes at these sites can have catastrophic effects particularly fires and explosions that pose significant risks to personnel and may result in extended outages, loss of productivity, and equipment and infrastructure failures.  However, these consequences can be avoided with suitable lightning protection design and installation by certified companies. Modern Lightning protection design requirements are not adequately addressed by the national standards. A common example is explosive volumes that are created due to off-gassing from vent stacks, etc.  While a well-designed lightn...

A direct lightning strike can cause severe damage to a building’s structure, and its internal electronic systems, putting lives at risk. From oil & gas rigs, tall towers, to high-rise offices, hospitals, to shopping centres to stadiums, a compliant lightning protection system, installed by a competent specialist is essential to minimising the damage that can occur. Lightning protection systems are used to prevent or lessen lightning strike damage to all facilities. They protect the internal and external components of a building, helping to prevent fires,  electrocution and destruction. Lightning protection can be provided from basic grounding rods to advanced dissipation arrays that prevent lightning from striking in a protected zone.  Working with LEC you will get a lightning protection system with the capability to eliminate the lightning strikes within zones of protection!  Our process Consultancy Design Manufacture Installation Testing and commissioning Maintenan...

 In today’s electronic world, electrical systems in every industry aren’t complete unless they incorporate surge protection devices. They dramatically improve the total operating efficiency and reliability of the electrical system. A surge protector is a device to protect electrical equipment from voltage spikes that may occur from lightning, power outage, short circuits, and many other natural occurrences. Power surges cause a great amount of heat to run along electrical wiring and cause the wire to burn because more voltage than the wire was designed to hold is being forced into it. A lightning surge protection devices functions in three ways: It prevents voltage spikes from stressing electrical equipment It ensures that the surge current flows away from the equipment It prevents secondary induced voltage from damaging the equipment Through common knowledge, there are two approaches to solve all your surge problems; even the ones occurring due to a lightning strike. To provide l...
