The Metal Oxide Arrester (MOA) represents the most advanced solution for over-voltage protection. By utilizing a Zinc oxide barrier, it significantly improves flow capacity compared to traditional silicon carbide arresters. Under nominal voltage, only microamp current flows; however, during lightning events, its non-linear characteristics allow thousands of amps to pass, effectively discharging energy and protecting critical transmission and distribution equipment.
