What is the Purpose of Installing a Lightning Protection for a Home?

You may have seen some houses that have lightning rods on top of their ridges. What is the actual purpose and benefit of this tool? Do all homes need to install it? How does it work and how to choose the right lightning rod? Read the following review to find out the answer.

A lightning rod is a device that functions to divert lightning strikes to the ground so that they do not damage buildings or electrical equipment inside them. Lightning rods usually consist of three main parts, namely the receiving end, the conducting cable, and the grounding end. The receiving end is a pointed part made of metal that is installed on the ridge of the housing. The conductor cable is the cable that connects the receiving end to the grounding end. The grounding end is the part that is connected to the ground or other metal object that can transmit electric current.

Purpose of Installing a Lightning Protection

The purpose of installing a lightning rod on the ridge of a house is to divert the electric current produced by lightning to the ground, so that it does not damage the house or cause a fire. Apart from that, lightning rods can also reduce the risk of electric shock for house occupants who are inside when lightning strikes.

Installing a lightning rod on the roof of your house is an important step to prevent losses due to lightning strikes. However, lightning rods cannot guarantee 100% protection from lightning, because there are other factors that influence the possibility of a strike, such as weather, location and building conditions. Therefore, apart from installing a lightning rod, house residents must also take other precautions, such as not using electronic equipment during heavy rain, not being near windows or doors, and not touching metal objects.

Benefits of Installing a Lightning Protection

The benefit of installing a lightning rod is to reduce the risk of loss due to lightning strikes. With a lightning rod, the electric current from a lightning strike will be diverted to the ground and not enter the house. This can prevent fires, short circuits or explosions which can harm property or life. Apart from that, lightning rods can also increase the feeling of security and comfort for house residents during the rainy season.

However, not all houses need to install lightning protection. There are several factors to consider before deciding to install a lightning rod, such as location, height, area and type of building. In general, it is advisable for houses that are located in highland areas, close to volcanoes, or frequently hit by lightning to install lightning protection. Likewise with houses that are more than 10 meters high, have an area of more than 100 square meters, or are made of flammable materials such as wood or bamboo.

Types of Lightning Protection on House Ridges

There are several types of lightning rods on house ridges, including:

Conventional lightning rod

A type of lightning rod that uses a metal rod as the receiving end of a lightning strike. This metal rod is installed on the ridge of the house and connected to the ground by a conductor cable. The advantage of this type of lightning rod is that it is easy to install and cheap. But the disadvantage is that the protection range is limited and is not effective for tall buildings.

Electrostatic lightning rod

A type of lightning rod that uses the principle of electrostatic induction to attract lightning strikes. This lightning rod is shaped like a ball or cone which is installed on the roof of the house and connected by a conducting cable to the ground. The advantage of this type of lightning rod is that its protection range is wider and more effective for tall buildings. The disadvantage is that it is more expensive and difficult to install.

How to Choose a Lightning Arrester

There are several things you need to pay attention to when choosing a lightning rod, including:

Types of lightning rods

There are two types of lightning rods that are commonly used, namely conventional and electrostatic. Conventional lightning rods are in the form of metal rods that are installed vertically on the roof of the house. This lightning rod works by attracting lightning strikes and channeling them to the ground through a conductor cable. Electrostatic lightning rods are in the form of balls or cones that are installed horizontally on the ridge of a house. This lightning rod works by producing an electrostatic field that can repel lightning strikes from the house.

Lightning rod distance

Lightning rod distance is the distance between the lightning rod and other highest points around the house, such as trees, electricity poles, or other buildings. The lightning rod distance must be greater than the lightning rod's protection radius, which is the maximum distance that the lightning rod can protect from lightning strikes. The protection radius of the lightning rod depends on the height and type of lightning rod. The higher and better the type of lightning rod, the larger the protection radius.

Lightning protection quality

The quality of the lightning rod determines how well the lightning rod can protect the house from lightning strikes. The quality of the lightning rod is influenced by the material, shape, size and installation of the lightning rod. Lightning rod materials must be rust-resistant, heat-resistant and have high electrical conductivity. The shape and size of the lightning rod must comply with the standards set by the relevant institution, such as SNI or NFPA. Installation of lightning rods must be carried out by experienced and certified experts.

Price of lightning rod

The price of lightning rods varies depending on the type, quality and number of lightning rods needed. The price of a lightning rod is also influenced by installation and maintenance costs. It's best to choose a lightning rod that suits your budget and needs, but doesn't sacrifice quality and safety.

That's the article about the purpose of installing a lightning rod on the ridge of a house and how to choose one. Hopefully this article is useful and can help you in making a decision. Don't forget to always maintain the safety and comfort of you and your family at home.
