Most of the surge protector design can provide a very significant function - allows multiple components to share a power outlet. Because the computer system is composed of various components, the surge protective device is indeed a very useful device. While another function of the surge protector’s power strip is to protect your electronic device of your computer from the damage of power surges which is much more important. In this article, we will learn about the surge protector (also known as surge suppressors), reveal the role, application and work results. In addition, we will also introduce what level of protection it can provide, and why can’t you get all the protection, even if you use a high-quality surge protector.
Basic Knowledge of Surge Protector
Surge protection system is mainly used to protect electronic equipment from the damage of the "surge". Therefore, if you want to know the role of the surge protector, you need to figure out two questions: What is the surge? Why do electric equipments need their protection? Surge or transient voltage refers to the voltage in the power flow significantly exceeds its rated level. In the U.S., the general standard voltage of home and office environments wirings is 120 volts. If the voltage exceeds 120 volts,cable surge protector will help to prevent the damage to the computer. The voltage is a representation of the unit of measurement of electrical potential difference. Therefore, you can see the voltage as the measurement unit of electrical pressure. When the voltage has increased for three nanoseconds (billionths of a second) or longer, it is known as the surge. When the voltage has increased only for nanosecond or two nanoseconds, it is known as spikes. If the surge or spike voltage is high enough, it could cause some serious damage to the computer. In fact, it is like a light bulb filament, it will heat and blown, but the principle is the same. The Increasing voltage even if not immediately damages the computer, also make components excessive wear and tear, and their service life will be reduced in the long run. In the next section, we will know about how the surge protector to prevent this from happening.
The Process of Surge Protection
In the most common surge protection device, there is metal oxide varistor (Metal Oxide Varistor, MOV), and it is used to transfer the excess voltage. MOV is composed of three parts: the middle is a metal oxide material, and two semiconductor s connect power supply and ground lines. The standard surge protection device will convey the current from the power outlet to the plurality of electrical and electronic equipments. If a surge or a spike appears making the voltage exceed the acceptable level, the surge protector will transfer the extra current to the power outlet ground.
