How Does A Surge Protector Perform Its Protective Function?

surge protective device is the abbreviation for what we commonly call a surge protector. It's considered an essential device for lightning protection in electronic equipment. Lightning is a common natural phenomenon, especially in the summer. When a lightning strikes, if a large amount of lightning current directly strikes power lines, signal transmission lines, or even high-rise buildings, it can cause significant damage to these devices or structures.

So how does surge protector provide protection? This is where lightning protection devices, such as lightning rods or surge protection device, come in. When encountering these powerful lightning currents, these devices divert the excess current directly into the ground, protecting power lines and other protected equipment from damage.
