For some people, rain can relax the mind and mind. Please try to imagine. The sound of rain, the cold wind, and the unique scent of rain wrap you around and calm you down. But one of the things that could hinder that calm was lightning. The voice of his boom can surprise you, it can even endanger you.
Why does the lightning phenomenon occur? When it rains or rains, the air and clouds rub against each other to generate electrical power. The electric force is in the form of a lightning-charged jump from one cloud to another, or from a cloud to the earth. Now, the air that the lightning bolt passed through expanded rapidly, making a thunder-like sound.
American scientist Benjamin Franklin created a lightning rod in 1752, looking at the risks of lightning. Certainly, lightning rods are familiar to the ears, aren't they? But do you know more about this? If you don't have an answer yet, Kania will introduce you to a lightning rod. Now see below.
What is a lightning rod?
As mentioned earlier, lightning rods are used to prevent the dangerous risks posed by lightning. Therefore, we strongly recommend that you install this object. This object can protect the building and its surroundings from lightning to prevent it from exploding or igniting. Lightning rods are usually installed on buildings such as houses, buildings, and skyscrapers.
Lightning rod parts
This object is divided into three parts: a lightning rod, a conductor cable, and a ground rod. The lightning rod is made of a metal or copper taper that is mounted upright on the building. The rod is coated with anti-corrosion material. The edges are tapered due to the charge that is easy to collect and release at the sharp edges.
Conductor cables are long copper wires. This cable is about 1-2 cm in diameter and is installed outside the building. Like the conductor cable, the ground rod is made of copper but armored. Stems about 1.5 cm in diameter and 1.8 to 3 meters long are planted on the ground.
How the lightning rod works
The operation of the lightning rod looks simple, but it is very complicated. The land of the earth is positively charged and the clouds are negatively charged. When the negative charge collects under the cloud, the positive ground charge is attracted upwards through the conductor cable and collects at the end of the lightning rod. Now, as the cloud approaches the stem, the negative charge of the cloud and the positive charge of the ground attract each other.
When the positive and negative charges meet, the charges are returned to the ground via the conductor cable. Why pour it on the ground? If the negative charge of the cloud remains above, the charge can jump around and harm objects below or around it. Therefore, the negative charge of the cloud is carried to the ground and neutralized by the positive charge of the ground.
Types of lightning rods
Two types of lightning rods are often used: conventional lightning rods and electrostatic lightning rods. The two are distinguished by their range of protection and placement from the danger of lightning strikes.
Conventional lightning rod
This type is closely related to Benjamin Franklin's first lightning rod. Since ancient times, this lightning rod has been the most frequently used lightning rod in the home to date. This simple form is very easy to find in a builder at a fairly cheap price. Traditional lightning rods are suitable for use in buildings and lands that are not too large, such as homes, shophouses, and shophouses.
Electrostatic lightning rod
This lightning rod has a wider range of protection than conventional lightning rods. The higher the placement, the wider the scope of its protection. Therefore, this type is common on vast lands and skyscrapers such as real estate, golf courses, mining areas, industrial areas, office buildings and skyscrapers. Unfortunately, electrostatic lightning rods are expensive and time consuming to install.
The building is protected by a roof, but the presence of lightning rods is very necessary. This object is very helpful in providing additional protection to prevent the building from catching fire or damaging the electronics inside. It also protects you from lightning strikes. Therefore, install a lightning rod in your home, yes!
