  • Difference between lightning arresters and LPS

    Lightning strikes are a common and often unpredictable natural phenomenon that can cause significant damage to buildings, equipment, and infrastructure. To mitigate the risk of lightning damage, lightning protection systems and lightning arresters are often used. While both of these systems are designed to protect against lightning strikes, there are important differences between them. In this article, we will explore the difference between lightning arresters and LPS (lightning protection systems), how they work, and when to use each one.

    What is a Lightning Protection System?

    Lightning Protection System

    A lightning protection system is a comprehensive set of measures designed to protect a structure or building from the effects of lightning strikes. It includes several components, including lightning rods, conductors, and grounding systems. A lightning rod, also known as an air terminal, is a metal rod or tube that is mounted on the roof of a building. It is designed to attract the lightning strike and conduct the current through a conductor to the grounding system. The conductor is a metal wire or cable that is attached to the lightning rod and extends down to the grounding system. The grounding system is a network of metal rods or plates that are buried in the ground, designed to dissipate the electrical charge into the earth.

    The primary function of a lightning protection system is to provide a path of least resistance for the lightning strike, directing the electrical charge away from the structure and into the ground. The system does not prevent the lightning strike from occurring, but it does provide a safe path for the electrical charge to dissipate.

    What is a Lightning Arrester?

    A lightning arrester, also known as a surge arrester or surge suppressor, is a device that is installed to protect electrical equipment from the damaging effects of electrical surges caused by lightning strikes. When lightning strikes an electrical system, it can cause a surge of electricity that can damage or destroy the equipment. A lightning arrester is designed to divert the surge of electricity away from the equipment and safely to ground, protecting the equipment from damage.

    There are two types of lightning arresters: gap-type and valve-type. Gap-type arresters work by ionizing the air in the gap between two electrodes, which creates a low-impedance path for the lightning surge to travel to ground. Valve-type arresters use metal oxide varistors (MOVs) to absorb the energy of the surge and prevent it from damaging the equipment.

    The primary function of a lightning arrester is to protect electrical equipment from the damaging effects of electrical surges caused by lightning strikes.

    Differences between Lightning Protection Systems and Lightning Arresters:

    While both lightning protection systems and lightning arresters are designed to protect against lightning strikes, there are several key differences between them.

  • Lightning arresters for buildings

    Lightning is a powerful and unpredictable natural phenomenon that can cause significant damage to buildings, infrastructure, and human life. Lightning strikes can result in fires, structural damage, and damage to electrical systems and equipment. As a result, it is essential to implement lightning protection systems for buildings to minimize the risk of damage and ensure the safety of building occupants. In this article, we will discuss lightning arresters for buildings.

    One of the most critical components of a lightning protection system for buildings is a lightning arrester. Lightning arresters are devices that are designed to protect electrical systems and equipment from high-voltage surges caused by lightning strikes. Two of the most common types of lightning arresters used for buildings are the Franklin rod air terminal and the ESE lightning arrester.

    Franklin Rod Air Terminal

    The Franklin rod air terminal, also known as the Franklin lightning rod, is a simple and effective method of lightning protection. The Franklin rod air terminal was first introduced in the mid-18th century by Benjamin Franklin, who discovered that lightning was a form of electrical discharge. The Franklin rod air terminal consists of a metal rod or rods that are installed on the roof of a building and connected to a grounding system.

    Copper Lightning Arrester

    The Franklin rod air terminal works by creating a path of least resistance for the electrical current produced by a lightning strike. When lightning strikes the Franklin rod air terminal, the electrical current is directed to the grounding system, preventing it from traveling through the building’s electrical systems and equipment.

    The Franklin rod air terminal is a reliable and cost-effective method of lightning protection, making it a popular choice for many buildings. However, it has some limitations. The Franklin rod air terminal is not effective against direct lightning strikes that occur within a few hundred feet of the building. Additionally, the Franklin rod air terminal must be installed correctly to be effective. If it is not installed correctly, it can actually increase the risk of damage from lightning strikes.

    ESE Lightning Arrester

    The ESE lightning arrester, also known as the early streamer emission lightning arrester, is a more advanced type of lightning arrester that provides a higher level of protection against lightning strikes. The ESE lightning arrester was first introduced in the 1970s and has since become a popular choice for modern buildings.

    The ESE lightning arrester works by emitting a streamer that travels toward the approaching lightning strike. The streamer ionizes the air, creating a path of least resistance for the electrical current produced by the lightning strike. This allows the electrical current to be safely diverted away from the building’s electrical systems and equipment.

    The ESE lightning arrester provides a higher level of protection against lightning strikes than the Franklin rod air terminal. It is effective against direct lightning strikes that occur within a few hundred feet of the building, as well as indirect lightning strikes. Additionally, the ESE lightning arrester can be installed at a lower height than the Franklin rod air terminal, reducing the visual impact on the building’s design.

    Choosing the Right Lightning Arrester for Your Building

    When it comes to choosing the right lightning arrester for your building, there are several factors to consider. These include the type of building, the height of the building, and the local weather patterns.

    For buildings that are less than 75 feet tall, the Franklin rod air terminal is a reliable and cost-effective method of lightning protection. However, for taller buildings or buildings located in areas with a high risk of lightning strikes, the ESE lightning arrester is a better choice. The ESE lightning arrester provides a higher level of protection against lightning strikes and can be installed at a lower height, reducing the visual impact on the building’s design.

    It is also important to consider the local weather patterns when choosing a lightning arrester for your building. Buildings located in areas with a high frequency of thunderstorms and lightning strikes will require a more robust lightning protection system than buildings located in areas with a lower frequency of thunderstorms and lightning strikes.

    In addition to choosing the right type of lightning arrester, it is important to ensure that the lightning protection system is installed correctly. Lightning protection systems must be designed and installed by professionals who are trained in lightning protection systems. They must also comply with national and international standards for lightning protection, such as NFPA 780 and IEC 62305.

    Surge Protection Systems

    In addition to lightning arresters, surge protection systems are an important component of a comprehensive lightning protection system for buildings. Surge protection systems are designed to protect electrical systems and equipment from power surges caused by lightning strikes, as well as other sources of electrical surges, such as power outages and equipment malfunctions.

    Surge protection systems work by limiting the voltage of an electrical surge, preventing it from damaging electrical systems and equipment. Surge protection systems can be installed at the building’s service entrance, as well as at individual electrical panels and equipment.

    There are several types of surge protection systems available, including transient voltage surge suppressors (TVSS), surge protective devices (SPD), and power conditioners. TVSS and SPD are the most common types of surge protection systems used for buildings.

    Transient Voltage Surge Suppressors (TVSS)

    TVSS are a type of surge protection device that is designed to protect electrical systems and equipment from transient voltage surges. TVSS are typically installed at the building’s service entrance and provide protection for the entire electrical system.

    TVSS work by detecting electrical surges and diverting them away from the electrical system. When an electrical surge is detected, the TVSS activates and redirects the electrical surge to the ground, preventing it from damaging electrical systems and equipment.

    Class B+C SPD

    Surge Protective Devices (SPD)

    SPD are a type of surge protection device that is designed to protect individual electrical panels and equipment from power surges. SPD are installed at the point where electrical power enters the electrical panel or equipment and provide protection for that specific panel or equipment.

    SPD work by detecting electrical surges and diverting them away from the electrical panel or equipment. When an electrical surge is detected, the SPD activates and redirects the electrical surge to the ground, preventing it from damaging the electrical panel or equipment.

    Power Conditioners

    Power conditioners are a type of surge protection device that is designed to protect electrical equipment from power quality issues, such as voltage sags, voltage spikes, and electrical noise. Power conditioners work by filtering out electrical noise and smoothing out voltage spikes and sags, ensuring that electrical equipment receives clean and stable power.

    Power conditioners are typically used in conjunction with TVSS and SPD to provide comprehensive protection against power surges and power quality issues.

    Lightning protection systems are essential for buildings to minimize the risk of damage and ensure the safety of building occupants. Lightning arresters, such as the Franklin rod air terminal and the ESE lightning arrester, are critical components of a lightning protection system. Surge protection systems, such as TVSS, SPD, and power conditioners, are also important components of a comprehensive lightning protection system.

    When choosing a lightning arrester and surge protection system for your building, it is important to consider the type of building, the height of the building, and the local weather patterns. It is also important to ensure that the lightning protection system is installed correctly and complies with national and international standards for lightning protection.

    By implementing a comprehensive lightning protection system, building owners and occupants can rest assured that their building and electrical systems are protected from the potentially devastating effects of lightning strikes and electrical surges.

  • Lightning protection in Patna, Bihar

    Patna, the capital of Bihar, is a city known for its rich history and cultural heritage. The city is situated in an area prone to thunderstorms and lightning strikes during the monsoon season. Lightning strikes can cause severe damage to buildings and infrastructure, and in some cases, can lead to loss of life. Therefore, it is crucial to have proper lightning protection systems in place.

    In this article, we will discuss conventional lightning protection systems and ESE lightning protection systems that are commonly used in Patna, Bihar.

    Conventional Lightning Protection System

    A conventional lightning protection system is a system that consists of a Franklin rod, a down conductor, and a grounding system. This system has been used for more than 200 years and is still widely used today.

    Copper Lightning Arrester

    Franklin Rod

    A Franklin rod is a metal rod made of copper or aluminum that is installed at the highest point of a building. The rod is pointed at the top, and it is designed to attract lightning strikes. When a lightning strike occurs, the rod provides a path of least resistance for the lightning to follow, thereby protecting the building from damage.

    Down Conductor

    A down conductor is a metal conductor that is installed on the side of a building and connects the Franklin rod to the grounding system. The down conductor provides a path for the lightning current to flow from the Franklin rod to the grounding system.

    Maintenance Free Chemical Earthing

    In a conventional lightning protection system, the grounding system is an essential component. The grounding system must be installed correctly to ensure that it provides a low resistance path for the lightning current to flow to the ground. The maintenance of the grounding system is also critical. Over time, the soil around the grounding system can become dry, and the resistance of the grounding system can increase. This can make the lightning protection system less effective.

    To overcome this problem, maintenance-free chemical earthing is used in Patna. This system involves the use of a chemical compound that is poured into the ground around the grounding system. The chemical compound helps to improve the conductivity of the soil and ensures that the grounding system provides a low resistance path for the lightning current to flow to the ground. This system is maintenance-free and can last for many years.

    ESE Lightning Protection System

    An ESE lightning protection system is a more advanced lightning protection system that is becoming increasingly popular in Patna. This system is designed to provide enhanced protection against lightning strikes and is more effective than a conventional lightning protection system.

    ESE Lightning Arrester

    An ESE lightning arrester is a device that is installed at the highest point of a building. The device is designed to create a strong electric field that can ionize the air around it. This ionization process helps to create a path of least resistance for the lightning to follow. When a lightning strike occurs, the lightning is attracted to the ESE lightning arrester, and the device provides a path for the lightning current to flow to the ground.

    GI Mast

    A GI mast is a metal mast that is installed on the roof of a building. The mast is connected to the ESE lightning arrester and provides a path for the lightning current to flow to the ground.

    Down Conductor

    A down conductor is a metal conductor that is installed on the side of a building and connects the GI mast to the grounding system. The down conductor provides a path for the lightning current to flow from the GI mast to the grounding system.

    Maintenance Free Chemical Earthing

    Earthing Materials

    In an ESE lightning protection system, the grounding system is also an important component. The grounding system must be installed correctly to ensure that it provides a low resistance path for the lightning current to flow to the ground. The maintenance of the grounding system is also critical. Over time, the soil around the grounding system can become dry, and the resistance of the grounding system can increase. This can make the lightning protection system less effective.

    To overcome this problem, maintenance-free chemical earthing is also used in ESE lightning protection systems in Patna. This system involves the use of a chemical compound that is poured into the ground around the grounding system. The chemical compound helps to improve the conductivity of the soil and ensures that the grounding system provides a low resistance path for the lightning current to flow to the ground. This system is maintenance-free and can last for many years.

    Advantages of ESE Lightning Protection System over Conventional Lightning Protection System

    There are several advantages of using an ESE lightning protection system over a conventional lightning protection system in Patna. These advantages include:

    Enhanced Protection

    An ESE lightning protection system provides enhanced protection against lightning strikes. The system is designed to create a strong electric field that can ionize the air around it. This ionization process helps to create a path of least resistance for the lightning to follow. This means that the ESE lightning protection system is more effective at preventing lightning strikes than a conventional lightning protection system.

    Cost-effective

    While the initial cost of installing an ESE lightning protection system may be higher than that of a conventional lightning protection system, the long-term cost is lower. This is because ESE lightning protection systems require less maintenance than conventional lightning protection systems. The maintenance-free chemical earthing used in ESE lightning protection systems also reduces the cost of maintenance.

    Aesthetic Appeal

    ESE lightning protection systems have a more modern and aesthetically pleasing design compared to conventional lightning protection systems. This means that they are more suitable for buildings with modern architecture and can enhance the overall look of a building.

    Easy Installation

    ESE lightning protection systems are easier to install than conventional lightning protection systems. This is because they require fewer components and can be installed in a shorter period of time. This also means that there is less disruption to the building during the installation process.

    Lightning strikes can cause severe damage to buildings and infrastructure, and in some cases, can lead to loss of life. Therefore, it is crucial to have proper lightning protection systems in place in Patna, Bihar. Conventional lightning protection systems and ESE lightning protection systems are commonly used in Patna. While conventional lightning protection systems have been in use for more than 200 years and are still widely used today, ESE lightning protection systems provide enhanced protection against lightning strikes and are more cost-effective in the long run.
