When it comes to protecting our valuable electronic devices, two terms often come up: lightning arrester and surge protector. While they both serve the purpose of safeguarding our electronics from electrical surges, they are not the same thing. In this article, we will explore the differences between lightning arresters and surge protectors, and help you understand which one is best suited for your needs.
What is a Lightning Arrester?
A lightning arrester, also known as a lightning rod or a lightning diverter, is a device designed to protect structures and electrical systems from the damaging effects of lightning strikes. It works by providing a low-resistance path for the lightning current to follow, diverting it away from the protected structure.
Lightning arresters are typically installed on the highest points of a structure, such as rooftops or poles, to attract lightning strikes and prevent them from damaging the building or its electrical systems. They are commonly used in areas prone to thunderstorms and lightning activity.
It’s important to note that lightning arresters are primarily designed to protect against lightning strikes and the resulting power surges caused by them. They are not as effective in protecting against other types of electrical surges, such as those caused by power grid fluctuations or equipment malfunctions.
What is a Surge Protector?
A surge protector, also known as a surge suppressor or a surge diverter, is a device designed to protect electronic devices from voltage spikes and power surges. These surges can occur due to various reasons, including lightning strikes, power grid fluctuations, or faulty electrical equipment.
A surge protector works by detecting the excess voltage and diverting it away from the connected devices, ensuring that they receive a steady and safe supply of power. It typically consists of multiple outlets, with some offering additional features like USB ports or Ethernet protection.
Surge protectors are commonly used in homes, offices, and other settings where electronic devices are connected to power sources. They provide a reliable defense against power surges, preventing damage to sensitive electronics such as computers, televisions, gaming consoles, and more.
The Key Differences
While both lightning arresters and surge protectors aim to protect against electrical surges, there are some key differences between the two:
- Function: Lightning arresters are specifically designed to divert lightning strikes away from structures and electrical systems. Surge protectors, on the other hand, provide protection against a wider range of electrical surges.
- Installation: Lightning arresters are typically installed on the exterior of a building, at the highest points, to attract lightning strikes. Surge protectors, on the other hand, are installed between the power source and the electronic devices they are meant to protect.
- Scope of Protection: Lightning arresters primarily protect against lightning strikes and the resulting power surges. Surge protectors, on the other hand, protect against a wider range of surges, including those caused by power grid fluctuations or faulty equipment.
- Cost: Lightning arresters are generally more expensive to install and maintain compared to surge protectors. Surge protectors are more affordable and readily available, making them a popular choice for protecting individual electronic devices.
Which One Should You Choose?
When it comes to choosing between a lightning arrester and a surge protector, it depends on your specific needs and circumstances. If you live in an area prone to lightning strikes and want to protect your entire structure and electrical systems, a lightning arrester may be the better option.
On the other hand, if you are primarily concerned about protecting your individual electronic devices from a wider range of electrical surges, a surge protector is the way to go. Surge protectors are more affordable and easier to install, making them a practical choice for most households and offices.
It’s worth noting that for optimal protection, you can also consider using both a lightning arrester and a surge protector in combination. This way, you can ensure that your structure and electrical systems are protected from lightning strikes, while also safeguarding your valuable electronic devices from other types of power surges.
Conclusion
In summary, lightning arresters and surge protectors serve different purposes when it comes to protecting against electrical surges. While lightning arresters are primarily designed to divert lightning strikes away from structures and electrical systems, surge protectors provide a wider range of protection against various types of power surges.
Understanding the differences between these two devices can help you make an informed decision on which one to choose based on your specific needs. Whether you opt for a lightning arrester, a surge protector, or both, investing in the right protection can save you from costly damage to your electronics and provide you with peace of mind.
