The function of the lightning arrester is to protect various electrical equipment in the power system from lightning electrical overvoltage, operating overvoltage, power frequency transient overvoltage and damage. The types of lightning arresters mainly include protection gaps, valve type lightning arresters and zinc oxide lightning arresters. The protection gap is mainly used to limit atmospheric overvoltage, and is generally used for protection of power distribution systems, lines, and substation incoming segments. Valve type lightning arrester and zinc oxide lightning protection device are used for protection of substations and power plants. The system is mainly used to limit atmospheric overvoltage in 500KV and below, and will also be used to limit internal overvoltage or internal in ultra high voltage system. Backup protection for overvoltage.
