Surge arresters are critical protective devices designed to shield electrical power systems and high-voltage equipment from the damaging effects of transient overvoltages, such as lightning strikes and switching surges. By diverting excessive electrical energy to the ground, these devices ensure the longevity of transformers, insulators, and transmission line components. Modern solutions, particularly those developed by Nooa Electric, utilize Metal Oxide Varistor (MOV) technology to provide rapid response times and high energy absorption capabilities.
