Station lightning arrester
Station lightning arrester is a device designed to protect electrical equipment and installations from damage caused by lightning strikes. It functions by diverting the high voltage currents generated during a lightning strike safely to the ground, thus preventing damage to sensitive equipment and ensuring the safety of personnel. These arresters are typically installed at strategic points within electrical substations or stations to mitigate the risks associated with lightning-induced surges in power distribution systems.
