1.3 Overview
The WFDT-7200 outdoor high-voltage AC automatic recloser (hereinafter referred to as recloser）is suitable for AC 50/60Hz，13.8kV or 27kV three-phase AC overhead power distribution network. The recloser can automatically perform breaking and reclosing operations in distribution network according to the predetermined breaking and reclosing sequence, which can quickly segment and isolate distribution line faults and improve the reliability of power supply.
