Lightning rod is an effective solution chosen by everyone. However, not everyone is knowledgeable about this product. Follow the article below of company P69 to better understand what is a lightning rod? Principle of operation, standard installation method from which to choose the right quality product.

What is lightning rod?

Lightning rod (Lightning rod or lightning rod) is a metal rod or metal object mounted on top of a building, electrically bonded using an electrical conductor to communicate with the ground or ” earth” through an electrode, designed to protect the building in the event of a lightning strike.

Lightning will strike a building target and will hit a lightning rod and then be transmitted to the ground via conductors, rather than through a building, where it could start a fire or cause an electric shock. . This is a very useful tool for humans, which can help us reduce the risk from lightning.

What are the benefits of lightning rods?

In the lightning protection system, the lightning rod has the most important task. If you are unlucky enough to be struck by lightning, a building or structure. The lightning rod will collect all the current so that the copper conductor transmits electricity to the ground.

Imagine if not equipped with this system, what will happen to your loving home or massive construction. Therefore, the lightning rod is the “treasure” that brings you safety on stormy days.

Working principle of lightning rod

As we all know, the ground is positively charged and the clouds are negatively charged. When thunderstorms come, it is also the time when the potential difference between the ground and the clouds is very large, thereby producing lightning. High places such as hills, trees, multi-storey houses, tall buildings will be prone to lightning strikes because of strong electric fields.

When it rains, it is also the time when the lightning needle starts to work. Because it is placed at the highest point in the shape of a spike, it will capture all lightning. The ground has a positive charge and the current in the lightning rod is a negative charge so it will be neutralized when traveling down.

What types of lightning rods are on the market?

Today, lightning rods are divided into 2 types:

1. Classical Lightning Needle

The classic lightning rod is also known as the lightning rod. The lightning rod is made from a long metal rod with a pointed end connecting it from the top to the ground. Later, to increase safety, the classic lightning rod was fitted with a porcelain sheath to prevent the bad influence of lightning.

The classic lightning rod only works when there is a storm coming and protects the area around the lightning protection system.

2. The lightning rod of the fairy light

Pioneer lightning lightning rod, also known as early discharge needle. The device actively launches upward beams to capture the plumes emitted from the clouds. Thanks to this principle of operation, it increases the distance and radius of protection around. That is why today’s buildings and houses often use lightning rods to collect lightning.

How to install a lightning conductor grounding system

– Step 1 : Dig trenches, holes or drill wells to ground

– Step 2 : Bury the electrodes in the ground

– Step 3 : Instructions to install the column and the foot of the column supporting the lightning rod

– Step 4 : Instructions for installing lightning conductors

– Step 5 : Return ground system ground

The lightning conductor grounding system helps to prevent the energy of lightning from directly affecting the structure to be protected. As a result, the project is fully protected. Follow the installation guide for lightning rod installation for the most detailed information.

How to choose the right lightning rod

What are the factors to choose the right lightning rod? You should check the following criteria:

1. Determine the need for use

Consider whether your house or building really needs a lightning protection system. You can consult experienced people around for advice. Because this system, if installed improperly, is likely to lead to lightning into the house and cause serious consequences.

2. Site survey, installation terrain characteristics

Next you should look around for the installation location of the system, the characteristics of the terrain as well as the resistance of the ground. These issues need to be calculated accurately to avoid wasting time and effort.

3. Research on parameters of lightning rods

After you have information about the lightning rod to use, you should go to the addresses that provide quality products. Choose the right lightning rod with the right parameters for your home or project. Protection radius, lead time are the two most important parameters when choosing a lightning rod.
