Overview of lightning surge arrester

What is a lightning surge arrester?

A surge arrester, often referred to as a surge protector or lightning arrester, is a device designed to protect electrical equipment from voltage spikes or transient overvoltages. These surges can occur due to lightning strikes, switching operations, or other disturbances in the electrical grid.

How lightning surge arrester work？

Surge arresters operate by providing a low-impedance path to divert excess voltage away from connected equipment. They typically consist of a metal oxide varistor (MOV) housed within a protective enclosure. When the voltage exceeds a certain threshold, the MOV conducts, effectively shunting the surge current to the ground.

This rapid response time is essential for effective surge protection, as it ensures that the voltage spike is suppressed before it can reach vulnerable devices. Additionally, surge arresters must be capable of handling high-energy surges without sustaining damage themselves, thus maintaining their protective capabilities over multiple events.
