There are various kinds of lightning arresters. The construction of lightning arresters differs depending on the kind, but the operating principle is the same. Surges heading towards the earth can use it as a low-resistance route. The primary function of this arresting gear is to protect the apparatus from the elements. Lightning arresters include the rod, electrolyte, spherical, multi gap, horn, and metal oxide. Product Specifications: Minimum Order Quantity Voltage Level No. Of Poles Brand Type Arrester Length Maximum Current Voltage Rating 5 Piece Low-Voltage Single Pole RPS lightning Customized Customized Customized The lightning arrester helps in protecting against lightning strikes. It provides a low impedance path to the ground for the current. It has a very strong central ion generating system that generates ions and it does not require any external source of power supply. It works on the principle of Corona Discharge. In Corona Discharge Technology, a region of plasma is produced to ease the flow of current. It helps the Arrester capture all the voltage of the lightning without damaging the essential equipment on target. What is Lightning Arrester? A lightning arrester, also known as a lightning isolator, is a device used on electric power transmission and telecommunication systems to protect the system’s insulation and conductors from the damaging effects of lightning. This has a high-voltage terminal and a ground terminal. Many people search for “Arrester Lightning” nothing wrong with that. Types of Lightning Arresters There are two types of Lightning Arresters are there that are commonly used- ESE Lightning Arrester Conventional Lightning Arrester What is ESE Lightning Arrester? ESE (Early Streamer Emission) Lightning Arrester is also known as Air Terminal or Ionizing. Lightning Rod is a cutting-edge external lightning protection system, and it is a safe and reliable solution to prevent direct lightning strikes on your building premises or solar installations. The other name of the ESE lightning arrester is known as Active Lightning Arrester, which offers an improved Radius of protection, allowing you to reduce the number of lightning arresters and down conductors needed for your building or solar project while still providing comprehensive protection. The lightning bolt begins by traveling through a downward leader that propagates in jumps in any direction. When the bolt hits the ground, it can strike any object. The lightning rod’s goal is to become the bolt’s point of discharge to achieve a controlled impact with no damage. To expect the descent of lightning and capture it before any other object within its protection area, the ESE air terminal emits a continuous upward leader with a time of the advance. The protection radius is determined by the ESE’s time of advance–The more the upward leader expects, the higher the downward leader is captured and prevents lightning strikes in a larger area. ESE lightning arrester can be installed in any type of structure, providing a desired and controlled point of impact for a lightning strike. It allows for protecting open areas, as well as objects on the building rooftop and the surrounding area because the time of advance provides the broad protection volume. What is Conventional Lightning Arrester? A conventional arrester works as a conductor which is mounted on the top of a tower/building and is connected to the ground via earthing strips and or through a wire, to protect the building or a tower at the time of sky lightning. If lightning strikes the building, it reaches the lightning arrester and conducts all the fault current to the earth via wire, harming no life, electrical and electronic equipment, and property. It comprises copper/aluminum and the down path is made up of Aluminium/copper/ GI Strips or wire. It can be installed in high-rise buildings, monuments, structures, and bridges to protect from lightning damage. What is Spike in Lightning Arrester? Lightning rods with spikes provide lightning protection for tall buildings and isolated buildings. This conventional surge arrester is installed on the roof of the building. Traditional types of surge arresters have special grounding systems designed to safely discharge the very high voltage currents associated with lightning strikes. How does an electrical arrester work? When potentially hazardous lightning strikes, the arrester activates and directs the lightning to the earth, where it dissipates harmlessly. It’s important to remember that an arrester does not stop lightning because doing so would be dangerous. It does, in fact, limit and mitigate the electrical charge as it provides a safe path for lightning to take instead of passing through your electrical devices. Where do you put a lightning arrester? Each lightning rod must be connected to at least two down conductors and must be installed at least 2 meters above the area it protects (including antennas, refrigerating towers, roofs, and tanks). What is a Surge Arrester? Surge arresters are types of protective device that functions to limit voltage on equipment by bypassing or discharging surge currents. It aids in the prevention of continuous flow, directs it to the ground, and can repeat this process. A surge protector is recognized as a spike suppressor, surge suppressor, or surge diverter. It is a device intended to protect electrical devices from voltage spikes. It guards the appliances by diverting the fault current to the ground. SPD is intended to restrict transient extreme voltages of environmental inception and redirects flow waves to earth to restrict the abundance of this overvoltage to a worth that isn’t unsafe for the electrical establishment and electric switchgear and control gear. Does black attract lightning? Others believe that if you go outside during a thunderstorm, you should not use a black umbrella or wear a black dress because lightning strikes black objects more frequently. Fortunately, the superstition that lightning preferentially strikes black objects is not true, as it is neither scientifically nor logically proven.  It also known as a surge diverter, is a device designed to protect substation equipment from

Leave a Comment / Chemical Earthing, Lightning Arrester /

Chemical Earthing is the method of transmitting the instantaneous discharge and is accomplished by attaching the non-current carrying section of the equipment or the supply system’s neutral to the ground. Ways to Protect Your Home From Lightning Strike: Lightning Rods: Lightning generates a tremendous quantity of heat and power. Residential and commercial structures employ lightning rods, also known as air terminals, to securely redirect such currents. Here’s how it works: A chemical metal rod is installed at the top of your house. That rod is linked to a copper cable that travels down to the earth and connects to another metal rod buried underneath. The electricity can safely dissipate into the Earth. Lightning rods are not a fault-free alternative. It simply cannot redirect all the energy at certain voltages, and some may go down into your exposed home. In addition, lightning rods should be placed by an expert, since they may cause significant harm if fitted poorly. Surge Protection Device: A power surge can appear in a variety of methods, including short circuits and power outrages, but lightning is the most damaging. A surge is an abrupt rise in voltage in your power system. It is possible if there is close lightning, even when it doesn’t strike your home directly. These surges have the potential to move along electricity, phone, or cable cables near your home. Large surges have the potential to cause instant harm to your appliances. Smaller surges may harm your appliances over time, causing them to fail.SPDs are dependable electrical grounding systems that are essential for safeguarding your house against electrical surges. Using metal oxide, these devices find, block, and redirect power away from your property. It’s a common misperception that broad power strips would safeguard your home’s equipment from a large surge.The optimum choice is to install a whole-house surge protecting device. Although, it is OK to augment the whole-house SPD with some other point-of-use SPD closer to the equipment or system. Disaster Management: Follow the weather forecast and unplug your electric devices. Make a lightning strategy to prepare your family to safeguard or unplug any major electronics and appliances. A lightning arrester, also called a thunder isolator, is the equipment used on electric communications networks and power transmission to protect the insulation and conductors of the system from the harmful effects of lightning. A lightning arrester usually has both high-voltage or ground terminals. Earthing is a link between electrical equipment and the ground via a low resistance channel that allows electrical energy to be discharged back to the earth. It is one of the most important safety requirements in an electrical system.A lightning arrestor is one of the most important components that is placed at the top of the building, towers, and other infrastructures. It collects all the electric charges from the light and passes them through the conducting wire. 5 Reasons Your Home Needs Lightning Arrester is: 1- Voltage Regulation: A network with various feeds or sources must have a common point that serves as a standardized reference point. The Earthing serves as a point of equilibrium. 2- Power Surge Protection: Earthing help defend against unexpected excessive surges and lightning strikes. Any lightning strikes on visible metal or gained through another channel connected to the earth line are discharged straight to the earth. 3- For Equipment healthy life: Light arrestor is critical for the proper operation of the system’s associated equipment in the long run as it transfers the upsurge in current through the wire. 4- Remove Stray Voltages: It inhibits stray voltage inside the line. There is zero potential difference to consider while designing the conductor. 5- Minimize the chances of Electric Shock: It reduces the electric-shock chances to a greater extent. Any leakage or defective current in the circuit caused the concentration of electric charge over electrical components’ surfaces. Earthing creates a low-resistance conductive conduit directly to the ground, carrying any leakage or faulty current. As a result, metal items, such as the device’s chassis that are linked to the earth line, are almost always safe to touch. As a result, it is preferable to ground every non-insulated body of an electrical item that may come into contact with humans. It is also advised that equipment that comes into touch with liquids or water be earthed. Installing an Lightning Arrester has become a prerequisite for surviving lightning without being injured. Earthing is the process of sending a charge directly to the ground using minimal resistance wire to get a rapid release of electrical energy. To provide the lowest resistance path for fault current leakage, a low impedance earthing cable is used. Installing a Grounding system is required to safeguard equipment and people from the defective current. Most decent earthing system kits may last up to a decade with little maintenance.

Introduction: What is Lightning Arrester? A Lightning Arrester is a device used to protect a variety of electrical equipment and systems from the effects of lightning. This device uses a technology called Corona discharge. Corona Discharge Technology uses the mechanism of discharge of high voltage in a short period by ionization of nearby air ions. A typical lightning arrester consists of a high-voltage terminal at the top, followed by a low-voltage terminal at the ground. We at Renown Power produce a Home Lightning Protection System. As per standard definition, a system of lightning protection for homes uses a combination of highly conductive copper and aluminum alloys. This renders a low impedance path to the ground that saves the electrical system from fault current damage. Types of a Lightning Arrester Let us discuss some types of lightning arresters. The choice of lightning arrester depends upon the following factors: Voltage Current Reliability Space available for installation, etc Heeding these above factors, there are twelve types of lightning arresters. Rod Gap Arrester Sphere Gap Arrester Horn Gap Arrester Multiple-Gap Arrester Impulse Protective Gap Arrester Electrolytic Arrester Expulsion Type Lightning Arrester Valve Type Lightning Arresters Thyrite Lightning Arrester Auto valve Arrester Oxide Film Arrester Metal Oxide Lightning Arrester Let us focus on some primary and important types of Arresters. Rod Gap Arrester It is one of the simplest types of Lightning Arresters. In the before-mentioned type, there is a gap between the end of the two rods. These two rods get connected to the earth and the line directly. The gap gets filled with air. When there is a higher voltage on the line, the air ionizes, producing a spark. In this fashion, the fault current passes to the earth. The process is explicated above in the snippet. Hence, the equipment is saved from potential damage. Sphere Gap Arrester In such types of lightning arresters, an air gap is provided between two spheres. Here, one of the spheres is grounded, and another is connected to the line. The diagram below represents the process in detail. There is a choking coil between the transformer and the ground, which heats up when the voltage rises. The air between the spheres heats up and tries to escape. But the corona discharge mechanism ionizes the air and the fault current passes through it. Thus, it saves potential damage to the device. Horn Gap Arrester This contains two horn-shaded pieces of metal. These two are separated by a small air gap and connected in a shunt between each conductor and earth. The distance between the two electrodes is optimum. This distance is filled with air that ionizes on fault current passage. Hence, the fault current is passed to the earth, and the inherent damage is stopped. Multiple Gap Arrester The schematic diagram above shows the details in brief. It consists of a small series of insulated through an air gap. The number of gaps depends upon the voltage. The gaps protect the device through the corona discharge. In it, air ionizes, and fault current passes through the ground. A resistor is added to stop the fault current even further. Electrolytic Arrester It has a high discharge capacity. It operates on the basic principles of an electrolytic cell. Expressly, here aluminum hydroxide deposits on the aluminum plates. The plate acts as a high resistor to a low voltage value and vice versa for a critical value. A voltage of more than 400 volts punctures the impedance. Hence the fault current passes to the ground. Thyrite Lightning Arrester These types of lightning arresters are commonly used for extremely high voltage conditions. It consists of a ceramic material called Thyrite, which has a variable resistance. The resistance is inversely proportional to the voltage applied at the ends of it. It contains a disc that is made conductive on both sides by spraying some conducting material. The disc is contained inside a translucent porcelain container. It is used as a joint in the container. When the lightning takes place, the voltage gap is filled through the breakdown of gaps. This saves the device from implied damage. Metal Oxide Lightning Arrester It is also called Zinc Oxide diverter. The schematic diagram below shows the process. These types of diverters are known as gapless surge diverters. The base material here is zinc, and the oxide manufactured is zinc oxide. It is a semiconducting material. This material is anesthetized by adding fine powders of insulating oxides. This powder is treated and then stuffed into a disc-shaped structure. The disc is then enclosed in an earthenware housing filled with sulfur hexafluoride. Thus, the arrester consists of a potential obstacle at the edges of zinc oxide. This potential barrier constrains the river and pathways of the current. Under normal conditions, it stops the flow of current. But when there is a potential breakage, the barrier collapses and the fault current passes to the ground. Thus, this stops the surge from damaging any device. Lightning Arrester for building A lightning arrester rod is a metallic arrangement used to protect a building from lightning and its surges. The lightning arrester for buildings is made from conducting metals like copper and iron. And alloys like brass, mild steel, etc. Therefore it has high earth coverage of around 60 meters. Lightning Arrester installation A lightning arrester installation must use the guidelines: The top of the terminal should be established at least 2 meters over the area that it shields. Each lightning rod should be blended with at least two down conductors. The bend radii must be less than 20 cm. Down-conductors shall be placed rather at the external part of the fabrication. The in-house resistance should be as low as possible (say less than 10 Ohms). All earthing equipment for a specific structure should be interconnected. Minerals should be added to lower soil resistivity (say Backfill compound). Comparison: Lightning Arrester VS Surge Arrester The major functions of the Surge Arrester are: It protects the installation from inside. The surge protector protects the system from lightning, switching, electrical faults, and
