Lightning strikes can cause significant damage to buildings, structures, and people. A single bolt of lightning can contain millions of volts of electricity. Hence, it can destroy electronic equipment, start fires, and even cause fatalities. To protect against lightning strikes, it is essential to install lightning arresters. In this blog, we will explore lightning arrester installation and the different types of arresters that can be used.

What is a Lightning Arrester?

A lightning arrester serves as a protective device designed to safeguard electrical systems and equipment from the damaging effects of lightning strikes. When a lightning strike occurs, the arrester redirects the electrical energy away from the system or equipment, providing a low-resistance path to the ground. Consequently, it prevents damages.

Types of Lightning Arresters

There are two main types of lightning arresters: the rod type arrester and the distribution arrester.

Rod Type Arresters

Conventional or gap-type arresters are known as rod-type arresters. And, they are the most commonly used type of arrester. However, they comprise a metal rod and a series of gaps. These divert the electrical energy from a lightning strike to the ground. Thus, it prevents damage to the electrical system or equipment.

Lightning Arrester Installation

One needs a skilled electrician to install lightning protectors. The way they put it up will depend on the kind of protector and what your electrical system or equipment need.

Rod Type Arrester Installation

The electrician must first identify the most vulnerable areas of the electrical system or equipment. Then, the electrician should install the arrester at the highest point of the system or equipment, which is typically the roof of the building. Next, the electrician should securely mount the arrester on a non-conductive base, such as a ceramic insulator. After that, the electrician should mount the base on a metallic mast or pole and securely ground it. Finally, the electrician should properly ground the arrester and ensure that there is a low-resistance path to the ground.

Distribution Arrester Installation

Using a distribution arrester, an electrician can protect the electrical system. Hence, the process starts by placing it where the system enters the building or equipment. Moreover, the arrester should be on a non-metallic base and connected carefully with a fuse or circuit breaker. However, the electrician must ensure proper grounding of the arrester to avoid any potential problems.

Best Practices for Lightning Arrester Installation

Here are 4 important things to keep in mind when using lightning arresters:

1. Get help from a professional who knows how to design and install lightning arresters properly, taking into account the specific electrical system or equipment, as well as the environment.

2. Check and maintain the lightning arresters regularly to make sure they are working right. This means inspecting their connections, mounting, and grounding.

3. Make sure the lightning arresters are installed the right way for them to work well. This includes making sure they are placed, mounted, grounded, and connected properly.

4. Test the lightning arresters regularly to make sure they are still working correctly.

Conclusion

Lightning arrester installation is an important aspect of electrical safety and protection. Therefore, if you need lightning arrester installation or maintenance, it is essential to seek the help of a qualified professional. They will ensure that your electrical system or equipment is properly protected.
