As technology continues to progress, the use of electronic devices in both residential and commercial buildings has become commonplace. However, one potential hazard that often goes overlooked is the danger of lightning strikes. This is where lightning arresters come in – they are designed to protect buildings and their occupants from the potentially harmful effects of lightning strikes. Here, we will discuss the different types of lightning arresters available today, and which types are most commonly used for residential and commercial purposes.
Firstly, it is important to understand what a lightning arrester is and how it works. A lightning arrester is a device that is installed in an electrical system to protect it from lightning strikes. When a lightning strike occurs, it can create a sudden surge of electricity that can damage electrical equipment and even cause fires. A lightning arrester works by diverting this surge of electricity away from the electrical system and safely into the ground.
Types of Lightning Arresters
There are several types of lightning arresters available today, including:
- Rod or Franklin Lightning Arrester: This type of lightning arrester is the oldest and most common type. It consists of a metal rod that is mounted on top of the building and connected to the ground with a wire. When lightning strikes, the surge of electricity is diverted through the rod and safely into the ground.
- Distribution or Horn Gap Lightning Arrester: This type of lightning arrester is commonly used in high voltage electrical systems. It consists of two electrodes that are separated by a small gap. When a surge of electricity passes through the gap, it ionizes the air and creates a conducting path to the ground, which diverts the surge of electricity away from the electrical system.
- Metal Oxide Varistor (MOV) Lightning Arrester: This type of lightning arrester is becoming increasingly popular due to its high energy absorption capabilities. It consists of a series of metal oxide discs that are connected between the electrical system and the ground. When a surge of electricity passes through the discs, the resistance of the discs decreases, allowing the surge of electricity to be safely diverted into the ground.
- Gas Discharge Tube (GDT) Lightning Arrester: This type of lightning arrester is commonly used in telecommunications and other low voltage applications. It consists of a gas-filled tube that is connected between the electrical system and the ground. When a surge of electricity passes through the tube, the gas ionizes and creates a conducting path to the ground, which diverts the surge of electricity away from the electrical system.
When it comes to residential and commercial applications, the most commonly used type of lightning arrester is the rod or Franklin lightning arrester. This is due to its simplicity, effectiveness, and cost-effectiveness. However, depending on the specific needs of a building, other types of lightning arresters may be used as well.
