Which Lightning Arrester Is Most Common?

Choosing the Right Lightning Arrester for Your Needs

When it comes to protecting our homes and buildings from the destructive power of lightning strikes, lightning arresters play a crucial role. These devices are designed to divert the electrical current from a lightning strike safely into the ground, preventing damage to our valuable assets and ensuring the safety of the people inside.

There are several types of lightning arresters available on the market, each with its own set of advantages and disadvantages. However, one type stands out as the most commonly used and widely recommended by experts: the surge arrester.

The Surge Arrester: A Popular Choice

Surge arresters, also known as surge protectors or lightning surge protectors, are the go-to choice for most residential and commercial applications. These devices are specifically designed to protect electrical systems from voltage surges caused by lightning strikes or other electrical disturbances.

Surge arresters work by diverting excess electrical energy from a lightning strike or power surge away from sensitive equipment and into the ground. By doing so, they prevent damage to appliances, electronics, and electrical systems, ensuring their longevity and reliability.

One of the reasons surge arresters are so popular is their versatility. They can be installed at various points in an electrical system, such as at the main service entrance, distribution panels, or individual equipment. This flexibility allows for comprehensive protection against lightning strikes and power surges, regardless of the size or complexity of the electrical system.

Factors to Consider When Choosing a Lightning Arrester

While surge arresters are the most commonly used lightning arresters, it’s important to consider a few factors before making a final decision:

  1. Application: Determine where the lightning arrester will be installed and what specific equipment or systems it needs to protect.
  2. Voltage Rating: Ensure that the lightning arrester’s voltage rating matches the voltage of the system it will be installed in.
  3. Surge Current Rating: Consider the maximum surge current the lightning arrester can handle. This rating should be higher than the expected surge current in order to provide effective protection.
  4. Response Time: Look for lightning arresters with fast response times to minimize the risk of damage from lightning strikes or power surges.
  5. Quality and Certification: Choose lightning arresters that meet industry standards and have been tested and certified for safety and performance.


When it comes to protecting our homes, buildings, and electrical systems from the destructive power of lightning strikes, surge arresters are the most commonly used and recommended choice. Their versatility, effectiveness, and ability to safeguard sensitive equipment make them an ideal solution for both residential and commercial applications.

Remember to consider factors such as application, voltage rating, surge current rating, response time, and quality when choosing a lightning arrester. By doing so, you can ensure that you have the right protection in place to safeguard your valuable assets and keep your property and people safe.
