A Lightning Arrester is a device installed at the substation that protects equipment from damage due to lightning. The arrester acts as a conductor of electricity and grounds the lightning strike so that it does not enter the substation equipment.
A lightning arrester is a device used to protect buildings and other structures from damage by lightning. Lightning arresters are installed on the roofs of buildings and on electrical substations. They work by providing a path for the electricity from a lightning strike to flow into the ground instead of into the building.
Lightning arresters are an important part of protecting against damage from lightning strikes, but they are not foolproof. It is still possible for lightning to cause damage even when an arrester is present. This is why it is important to have other measures in place to protect against lightning strikes, such as surge protectors.

Lightning Arrester for Home
A lightning arrester is a device that helps to protect your home from damage caused by lightning. It is installed between the ground and the building, and it acts as a barrier to prevent the flow of electricity from the ground to the building. When lightning strikes, the current from the ground is diverted through the arrester and into the earth, away from your home.
Lightning arresters are an important part of any home protection plan, especially in areas where thunderstorms are common. They can help to prevent fires and other damage caused by lightning, and they can also provide peace of mind knowing that your home is better protected against this type of natural disaster.
Lightning Arrester Price
When it comes to protecting your home or business from lightning, you can’t put a price on peace of mind. But when it comes to the actual cost of a lightning arrester, there are a few factors to consider. The type of building, the height of the structure, and the location all play a role in determining the price.
For most homes and small businesses, a basic air-terminal system is usually sufficient and can be installed for around $500-$1000. Larger buildings or those located in high-risk areas may require a more sophisticated system which can cost upwards of $5000. However, even the most expensive system is worth the investment when you consider the potential damage that could be caused by a lightning strike.
How Lightning Arrester Works
A lightning arrester is a device used to protect electrical equipment from damage due to lightning strikes. Lightning arresters are also known as surge suppressors or surge protection devices (SPDs).
Lightning arresters work by providing a low-resistance path for the electricity from a lightning strike to follow, thereby preventing it from damaging sensitive electronic equipment.
In most cases, the arrester will be installed at the point where the power enters the building.
When a lightning strike occurs, the high voltage of the strike will cause an electrical current to flow through the air and into any conductive object that it comes into contact with. If this current were to enter sensitive electronic equipment, it could damage or destroy the equipment.
The purpose of a lightning arrester is to provide a conductive path for this current to flow through so that it does not enter the sensitive equipment. The arrester works by diverting the current away from sensitive electronics and into itself where it can be safely dissipated.
One common type of lightning arrester consists of a metal rod that is placed atop a building or other structure.
Therod is connected to a grounding system that provides an alternate path forthe current to follow should a strike occur nearby.
Another typeof SPD is installed inline with power cables and features one ormore metal oxide varistors (MOVs) that divert currents away fromelectronics when they become overloaded..
Lightning Arrester Types for Building
When it comes to protecting your home or business from lightning strikes, there are a few different types of lightning arresters you can choose from. Here is a look at the most common types of lightning arresters and how they work:
1. Surge Protectors: These devices are designed to protect your electronics from power surges caused by lightning strikes.
They work by redirecting excess electricity away from your equipment and into the ground.
2. Lightning Rods: Lightning rods are tall metal rods that are installed on the roof of a building. They act as a pathway for lightning to travel into the ground, safely away from the structure.
3. Grounding Systems: Grounding systems provide an alternate path for electricity to flow in the event of a lightning strike. This helps to protect against damage to electrical systems and components.
Difference between Lightning Arrester And Surge Arrester
When it comes to electrical protection, there are two main types of devices: surge arresters and lightning arresters. Both devices serve the purpose of protecting against voltage spikes, but they work in different ways. Here’s a look at the key difference between these two types of devices:
Lightning Arresters: Lightning arresters are designed to protect against direct lightning strikes. These devices are installed at the point where a lightning strike is most likely to occur, such as on tall buildings or near power lines. When a lightning strike occurs, the device absorbs the excess voltage and dissipates it safely away from any sensitive equipment.
Surge Arresters: Surge arresters are designed to protect against indirect voltage spikes that can occur due to things like power line faults or transformer failures. These devices are installed upstream of sensitive equipment and work by diverting excess voltage away from delicate components.
Lightning Arrester in Transformer
A lightning arrester is a device used to protect electrical equipment from damage caused by lightning strikes. The arrester is installed between the ground and the equipment, and it diverts the surge of electricity away from the equipment to prevent damage.
Lightning arresters are important in protecting transformer because transformers are expensive pieces of equipment that can be easily damaged by electrical surges.
The arresters help to prolong the life of the transformer by absorbing the surge of electricity and preventing it from reaching the transformer.
When a lightning strike occurs, the current from the strike will flow through the air gap of the arrester and into the ground. This prevents any damage to the transformer as well as any other electrical equipment that is connected to it.
Lightning arresters are an important part of keeping transformers safe from damage, and they should be regularly checked to ensure that they are in good working order.
Lightning Arrester Rod
A lightning arrester rod is a steel rod that is placed on the highest point of a structure. The rod intercepts lightning strikes and dissipates the electrical current to avoid damage to the structure.

What is the Function of Lightning Arrester in Substation?
When a substation experiences a lightning strike, the resulting surge of electricity can cause damage to equipment and poses a safety hazard. A lightning arrester is installed at the substation to protect against this type of damage.
The lightning arrester works by providing a path for the surge of electricity to flow through, rather than through the substation equipment.
When the strike occurs, the arrester will conduct the electrical current away from the substation and into the ground. This protects the equipment from being damaged by the high levels of electricity.
It is important to have a properly functioning lightning arrester in place at a substation as they provide an essential level of protection.
Without one, there would be a greater risk of damage to equipment and potential injuries to personnel.
Where is the Lightning Arrester in a Substation?
The lightning arrester is a key component in a substation and its purpose is to protect equipment from damage caused by lightning strikes. The arrestor is typically located at the highest point in the substation, such as on the roof of a building, in order to provide the best possible protection. In some cases, the arrestor may also be located underground.
Conclusion
A lightning arrester is a device used to protect electrical equipment from damage caused by lightning strikes. They are typically installed at the point where a lightning strike is most likely to occur, such as on tall buildings or near power lines. Lightning arresters work by dissipating the electrical energy of a lightning strike so that it does not cause damage to the equipment.
