What Is A Surge Protector?

In daily life, electricity is an important energy source that we cannot do without. From skyscrapers to electric lights, electricity is needed. However, in the power network, there is a data that is a headache. It will seriously affect our power system and may even cause accidents and economic property losses. It is overvoltage. In order to protect our power system, surge protectors have emerged to protect our safety. So what exactly is a surge protector? Today, the editor will take you to find out what a surge protector is.

Before understanding what a surge protector is, we need to understand what overvoltage is. Under normal circumstances, our power system is at a rated voltage, and each electrical appliance works in an orderly and safe manner at the rated voltage. However, due to some reasons (lightning, operating errors, short circuits, etc.), the voltage of our power system will suddenly increase and exceed our specified standards. We call this phenomenon overvoltage. Once an overvoltage phenomenon occurs in the system, the electrical appliances will work at a higher voltage, which will damage the electrical appliances at the least, and even cause accidents in serious cases, posing a huge threat to life and property. Therefore, we need to use surge protective device to protect our lives and property.

surge protection device, as the name implies, are components that prevent surge (overvoltage) phenomena. We generally connect it in parallel with the power system we need to protect, and one end of it is grounded to discharge overcurrent. When the power system is working normally, it can be equivalent to a large resistor and will not affect the normal operation of our power system. When the system generates overvoltage, it will quickly reduce the resistance and conduct the current to the grounding device, thereby limiting the overvoltage and effectively protecting the power system. What is a surge protector? I believe everyone now has a certain understanding.
