  • Working principle of ESE lightning arresters

    A lightning arrester is a device used to protect electrical systems from lightning strikes. It operates by providing a low impedance path for the high voltage lightning surge to ground. In this article, we will discuss the working principle of ESE (Early Streamer Emission) lightning arresters. We will start with a brief overview of the types of lightning arresters available in the market, followed by the working principle of ESE lightning arresters. We will then discuss the advantages and disadvantages of ESE lightning arresters and conclude with some examples of their applications.

    Types of Lightning Arresters

    There are three types of lightning arresters available in the market, which are:

    Rod Gap Arresters

    Rod gap arresters are the oldest type of lightning arresters. They consist of two electrodes separated by a small air gap. When a high voltage surge occurs, the air between the electrodes ionizes, providing a low impedance path to ground. Rod gap arresters are inexpensive but have some limitations. They have a high spark-over voltage and a long response time.

    Metal Oxide Arresters

    Metal oxide arresters are the most common type of lightning arresters used today. They consist of a stack of zinc oxide discs sandwiched between two metal plates. When a high voltage surge occurs, the zinc oxide discs conduct the surge to ground. Metal oxide arresters have a low spark-over voltage and a fast response time.

    Early Streamer Emission (ESE) Arresters

    ESE arresters are the newest type of lightning arresters. They use a special design to create a streamer of ionized air before a lightning strike occurs. This streamer provides a low impedance path to ground, preventing the lightning from striking the protected structure. ESE arresters have a lower cost than traditional lightning protection systems and are more effective in protecting structures.

    Working Principle of ESE Lightning Arresters

    ESE lightning arresters operate on the principle of early streamer emission. The device contains a metal rod or mesh that is connected to a low impedance path to ground. When a high voltage surge occurs, the ESE arrester produces an upward streamer of ionized air from the tip of the rod or mesh. The streamer attracts the lightning to the rod, preventing it from striking the protected structure.

    The design of the ESE arrester is critical to its performance. The device must be placed at the highest point of the protected structure to provide the most effective protection. The height of the ESE arrester must also be greater than the height of any nearby objects. This ensures that the ESE arrester is the most attractive target for the lightning.

    The ESE arrester contains a triggering system that causes the device to produce a streamer of ionized air when the electric field strength exceeds a predetermined threshold. The triggering system may be based on a spark gap or a semiconductor device. The triggering system must be carefully designed to ensure that the ESE arrester produces a streamer of ionized air before the lightning strikes.

    Advantages of ESE Lightning Arresters

    ESE lightning arresters have several advantages over traditional lightning protection systems. These advantages include:

    Cost

    ESE lightning arresters are less expensive than traditional lightning protection systems. This makes them an attractive option for many applications.

    Low Maintenance

    ESE lightning arresters require little or no maintenance. They are designed to be self-cleaning, meaning that any debris or contaminants that accumulate on the device will be washed away by rain.

    Effectiveness

    ESE lightning arresters are more effective than traditional lightning protection systems. They provide a low impedance path to ground, preventing the lightning from striking the protected structure.

    Easy to Install

    ESE lightning arresters are easy to install. They require no special tools or equipment, and can be installed by a single person.

    Applications of ESE Lightning Arresters

    ESE lightning arresters are used in a variety of applications to protect structures and equipment from lightning strikes. Some of the most common applications of ESE lightning arresters include:

    Residential and Commercial Buildings – ESE lightning arresters are used to protect residential and commercial buildings from lightning strikes. They are installed on the roof of the building and provide a low impedance path to ground.

    In conclusion, ESE lightning arresters are an effective and cost-efficient solution for protecting structures and equipment from lightning strikes. They operate on the principle of early streamer emission and provide a low impedance path to ground. ESE lightning arresters have several advantages over traditional lightning protection systems, including lower cost, greater effectiveness, ease of installation, and low maintenance. However, they also have some limitations that must be considered, such as limited coverage area, dependence on weather conditions, and the need for proper installation. ESE lightning arresters are used in a variety of applications, including residential and commercial buildings, telecommunications and broadcasting towers, industrial facilities, and airports.

  • 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.

    Copper Lightning Arrester

    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.

We will also explore the benefits of using maintenance-free chemical earthing instead of traditional earthing methods.

    What is an ESE Lightning Protection System?

    An ESE lightning protection system is designed to protect buildings and structures from direct and indirect lightning strikes. It works by emitting a streamer, which is an ionized channel that is capable of attracting lightning strikes. The ESE lightning protection system has a unique design that enables it to emit the streamer earlier than other types of systems, giving it an advantage in attracting lightning strikes.

    Installation Process of ESE Lightning Protection System

    The installation process of an ESE lightning protection system is similar to that of a conventional system. However, there are some differences due to the unique design of the ESE system. The installation process typically involves the following steps:

    Step 1: Site Assessment

    The first step in the installation process is a site assessment. This involves assessing the building or structure to determine the level of protection required. The assessment takes into account the size and shape of the building, the location, and the surrounding environment. The assessment is critical to ensuring that the ESE lightning protection system is designed to provide the necessary level of protection.

    Step 2: Design

    Once the site assessment is complete, the design of the ESE lightning protection system can begin. The design takes into account the results of the site assessment and is tailored to the specific needs of the building or structure.

    Step 3: Installation of Air Terminals

    The air terminals are the most visible part of the lightning protection system. They are installed on the roof of the building or structure and are designed to attract lightning strikes. The air terminals are typically made of SS Metal.

    Step 4: Installation of Conductors

    The conductors are the cables that connect the air terminals to the grounding system. They are designed to conduct the electrical charge from a lightning strike safely into the ground. The conductors are typically made of copper or aluminum and are installed along the roof and down the sides of the building.

    Step 5: Installation of Grounding System

    The grounding system is designed to provide a path for the electrical charge from a lightning strike to safely dissipate into the ground. The grounding system typically consists of grounding rods and conductors that are buried in the ground. The grounding rods are installed at a sufficient depth to ensure a good connection with the soil.
