In this article, we’ll explore the differences between cheap and high-quality surge protectors, and what you need to know to make an informed decision.
What is a Surge Protector, and Why Do I Need One?
A surge protector, also known as a surge suppressor or surge diverter, is a device that protects your electronic equipment from voltage spikes and surges that can occur in your home or office’s electrical system. These devices are designed to absorb or divert electrical surges, spikes, and noise, which can cause damage to your devices or even start a fire.
You may think that power surges are rare, but they can occur more frequently than you think. Here are some common causes of power surges:
- Lightning strikes: During a thunderstorm, a lightning strike can cause a massive power surge that can travel through your electrical system.
- Electrical grid switching: When the power company switches or maintains the electrical grid, it can cause power surges.
- Appliance failures: When an appliance, such as a refrigerator or air conditioner, fails, it can cause a power surge.
- Downed power lines: When power lines are damaged or downed, it can cause power surges.
Without a surge protector, your devices are exposed to these power surges, which can cause damage or even complete failure. This is especially true for sensitive electronics, such as computers, televisions, and audio equipment.
