What Is a Surge Arrester?
Surge arresters are devices used to protect electrical systems and equipment from lightning and overvoltage.
When overvoltage reaches electrical equipment, these devices absorb the energy, minimizing damage. They typically handle overvoltages caused by lightning or power system switching, thus protecting the power system and connected equipment while ensuring proper electricity supply.
In mobile phone base stations, surge arresters safeguard communication equipment from overvoltage. In power distribution systems, they help stabilize the power supply and ensure safe, stable power delivery to consumers. They are also used in power conversion equipment and industrial electrical installations.
