Common overvoltage protection components or devices include lightning arresters, varistors, and lightning arresters. In the field of communication power supply, in order to prevent the lightning high voltage from causing great damage to it, a varistor is usually arranged to protect against overvoltage. When a momentary high voltage generated by lightning is applied across the varistor, the varistor resistance becomes infinitely small, causing the varistor to conduct and introduce a large current generated by the lightning into the ground, thereby protecting the power supply device from lightning damage. On the power system side, the lightning protection device is usually used to protect the AC and DC from overvoltage.
