Surge Arrester

Surge arresters are designed to protect electrical systems from voltage surges caused by lightning strikes, switching operations, or other transient events. These devices divert excess voltage safely to the ground, preventing damage to sensitive equipment and ensuring system stability. Made from metal oxide varistors (MOVs) or silicon carbide, surge arresters offer high energy absorption capacity and fast response time. Commonly used in power grids, substations, and industrial facilities, they comply with IEC 60099 standards and provide a cost-effective, reliable solution for surge protection in electrical installations.
