What is Overvoltage protection

Overvoltage protection is a type of protection that disconnects or reduces the voltage of a controlled device when the protected line voltage exceeds a predetermined maximum value.

Overvoltage protection, also called overvoltage protection, is a type of protection that disconnects the power supply or reduces the voltage of the controlled device when the voltage exceeds a predetermined maximum value. There are many overvoltage protectors that come into being, some of which are housed inside the equipment and some are installed on the power supply side. With the protection of overvoltage protectors, we are more secure when using electrical equipment.

Common overvoltage protection components or devices include lightning protectors, varistors, and arresters. In the field of communications power supplies, varistors are often configured for overvoltage and lightning protection in order to prevent lightning high voltages from causing momentary damage to them. When a lightning high voltage is applied to both ends of the varistor, the resistance of the varistor becomes infinitely small, which makes the varistor turn on and introduces a large current generated by the lightning into the earth, thereby protecting the power supply device from lightning damage. In the power system side, surge protectors are usually used to overvoltage protection AC and DC.
