  • Different types of lightning protection systems

    Lightning is a powerful and potentially dangerous natural phenomenon that can strike without warning. It can cause significant damage to buildings, electrical systems, and people. To protect against lightning strikes, lightning protection systems (LPS) are installed in buildings and other structures. There are different types of lightning protection systems available, including direct and indirect lightning protection systems. In this article, we will discuss the different types of lightning protection systems in detail.

    Direct Lightning Protection Systems

    Direct lightning protection systems are designed to intercept and conduct lightning strikes to the ground, preventing damage to the structure and its occupants. These systems include lightning rods and early streamer emission (ESE) systems.

    Franklin Rod LPS

    The Franklin rod LPS, also known as a lightning rod or air terminal, is the oldest and most common type of lightning protection system. It consists of a metal rod or a conductor installed at the highest point of a structure, typically on the roof. The rod or conductor is connected to a grounding system that provides a low-resistance path for the lightning to travel to the ground.

    When lightning strikes the structure, the Franklin rod LPS intercepts the strike and conducts it to the ground, dissipating the electrical energy harmlessly. The Franklin rod LPS works by creating a path of least resistance for the lightning to follow, reducing the risk of damage to the structure and its occupants.

    Franklin rod LPS is suitable for most buildings and structures, including residential and commercial buildings, factories, and high-rise buildings. They are relatively inexpensive and straightforward to install.

    ESE LPS

    Early Streamer Emission (ESE) LPS is a newer type of lightning protection system that is designed to attract and capture lightning strikes before they can damage a structure. ESE LPS use a special ionization system that emits a streamer of ions into the air before a lightning strike occurs. This ionization system creates an upward streamer, which can attract the lightning strike towards the system.

    ESE LPS is installed on the roof of the building and connected to the grounding system. They have a larger coverage area than Franklin rod LPS and are more sensitive to incoming lightning strikes. This makes them more effective at protecting large structures such as airports, wind turbines, and communication towers.

    ESE LPS is more expensive than Franklin rod LPS, but they are more effective and provide a higher level of protection. They are also easier to install and require less maintenance.

    Indirect Lightning Protection Systems

    Indirect lightning protection systems are designed to protect electrical systems and equipment from the effects of lightning strikes, such as power surges and voltage spikes. These systems include surge protection devices and grounding systems.

    Class B SPD

    Surge Protection Devices

    Surge protection devices (SPD) are electronic devices designed to protect electrical systems and equipment from power surges and voltage spikes caused by lightning strikes. They work by limiting the amount of electrical energy that can flow through the system, preventing damage to the equipment.

    SPDs are installed in the electrical system, typically at the point where the power enters the building. They are also installed on individual pieces of equipment to protect them from power surges. SPDs are available in different types, including plug-in, panel-mounted, and whole-house units.

    SPDs are effective at protecting electrical systems and equipment from lightning strikes, but they do not protect the structure from the physical effects of lightning strikes. They are also limited in their ability to protect against direct lightning strikes.

    Earthing Materials

    Grounding Systems

    Grounding systems are an essential component of any lightning protection system. They provide a low-resistance path for the lightning to travel to the ground, dissipating the electrical energy harmlessly. Grounding systems consist of a network of conductive materials, including wires, rods, and plates, installed in the ground around the structure.

    Grounding systems work by creating a path of least resistance for the lightning to follow, reducing the risk of damage to the electrical system and equipment. They also provide a stable reference point for the electrical system, reducing the risk of electrical shocks and fires.

    Grounding systems are required by electrical codes and regulations and must be installed by qualified professionals. They must also be inspected and maintained regularly to ensure they are working correctly.

  • Installation process of conventional LPS

    Lightning strikes can cause extensive damage to buildings and other structures. Fortunately, the installation of a conventional LPS (lightning protection system) can mitigate the risks associated with lightning strikes. The installation process involves a series of steps that are designed to ensure the safety and protection of the structure. In this article, we will discuss the installation process of a conventional lightning protection system in detail.

    Step 1: Site Assessment

    The first step in the installation process of a conventional lightning protection system is to conduct a site assessment. This assessment involves the evaluation of the structure to be protected, including its size, shape, and height. The site assessment also considers the type of roof, the nature of the soil, and the presence of any metallic objects in the vicinity of the structure.

    The site assessment is typically carried out by a qualified professional, who has expertise in the design and installation of lightning protection systems. The purpose of the site assessment is to identify the risks associated with lightning strikes and to develop a design that provides adequate protection to the structure.

    Step 2: Design of the Lightning Protection System

    Copper Lightning Arrester

    The design of the lightning protection system is critical to its effectiveness. The design process involves the selection of appropriate materials and components, including air terminals, conductors, and grounding systems. The design must also take into account the specific requirements of the structure and the applicable building codes and standards.

    The air terminals, which are also known as lightning rods, are typically made of copper or aluminum and are installed on the roof of the structure. The air terminals intercept the lightning strikes and channel the electrical charge through the conductors to the grounding system. The conductors are usually made of copper or aluminum and are installed on the roof and sides of the structure. The grounding system, which consists of a series of copper or aluminum rods driven into the earth, provides a low-resistance path for the electrical charge to dissipate safely into the ground.

    The design of the lightning protection system must take into account the potential for indirect lightning strikes, which can occur when lightning strikes nearby objects, such as trees or other buildings. The system must also be designed to protect against surges in power and other electrical disturbances.

    Step 3: Installation of Air Terminals

    The installation of air terminals is the next step in the installation process of a conventional lightning protection system. The air terminals are installed on the roof of the structure and are spaced at regular intervals. The number and placement of air terminals are determined by the size and shape of the structure and the local building codes and standards.

    The air terminals are typically attached to the roof using specialized clamps, which are designed to provide a secure and electrically conductive connection. The installation of air terminals must be carried out in a manner that does not damage the roof or the structural integrity of the building.

    Step 4: Installation of Conductors

    Once the air terminals are installed, the next step is to install the conductors. The conductors are used to carry the electrical charge from the air terminals to the grounding system. The conductors are installed on the roof and sides of the structure, and are typically attached to the air terminals using specialized fittings.

    The conductors must be installed in such a way as to provide a continuous and electrically conductive path from the air terminals to the grounding system. The installation of conductors must be carried out in a manner that does not damage the roof or the structural integrity of the building.

    Step 5: Installation of Grounding System

    The final step in the installation process of a conventional lightning protection system is the installation of the grounding system. The grounding system provides a low-resistance path for the electrical charge to dissipate safely into the ground. The grounding system consists of a series of copper or aluminum rods that are driven into the earth at regular intervals.

    The number and size of the grounding rods are determined by the size and shape of the structure, the soil conditions, and the local building codes and standards. The grounding rods must be installed at a sufficient depth to ensure a good connection with the soil.

    The grounding rods are connected to the conductors using specialized fittings and connectors. The connection must be secure and electrically conductive to ensure that the electrical charge is safely dissipated into the ground.

    Step 6: Testing and Certification

    Once the lightning protection system is installed, it must be tested to ensure that it is functioning correctly and providing adequate protection to the structure. The testing process involves the use of specialized equipment to measure the electrical resistance of the system and to verify that the system is grounded properly.

    The testing must be carried out by a qualified professional, who has expertise in the design and installation of lightning protection systems. The testing process typically involves the use of specialized equipment, such as a megohmmeter, to measure the electrical resistance of the system.

    Once the testing is complete, the lightning protection system must be certified by a qualified professional. The certification process involves the verification that the lightning protection system is in compliance with local building codes and standards and is providing the necessary level of protection to the structure.

    Step 7: Maintenance and Inspection

    The maintenance and inspection of a conventional lightning protection system are critical to its effectiveness. The system must be inspected and maintained regularly to ensure that it is functioning correctly and providing adequate protection to the structure.

    The maintenance of the lightning protection system involves inspecting the air terminals, conductors, and grounding system for any damage or wear and tear. Any damaged components must be repaired or replaced immediately to ensure the system continues to provide adequate protection.

    It is also important to keep trees and other vegetation away from the air terminals, conductors, and grounding system. Trees can grow and come into contact with the air terminals and conductors, which can cause damage to the system or interfere with its operation.

    In addition to regular maintenance, it is important to have the lightning protection system inspected and tested periodically by a qualified professional. This will ensure that the system is in compliance with local codes and standards and is providing the necessary level of protection.

    Installing a conventional lightning protection system is an important step in protecting your building or structure from the damaging effects of lightning strikes. The installation process involves a site assessment, design of the system, installation of air terminals, conductors, and grounding system, and testing and maintenance.

    It is important to work with a qualified professional to ensure that the lightning protection system is designed and installed correctly and is in compliance with local codes and standards. Regular maintenance and periodic inspections are also necessary to ensure that the system is functioning correctly and providing the necessary level of protection.

    Investing in a conventional lightning protection system can save you from costly damage and downtime due to lightning strikes. By following the proper installation and maintenance procedures, you can ensure that your building or structure is protected from the unpredictable and potentially dangerous effects of lightning.
