Cover-Type FTU Feeder Terminal
Product Description
Mainly applied to pole-mounted switches on 10kV distribution lines. The distribution automation feeder terminal is primarily used for monitoring line operation status, switch equipment status, fault detection, and switch control on 10kV lines. It can also utilize centralized, adaptive local, voltage-time, and voltage-current-time feeder automation functions for fault detection, isolation, and restoration of power supply to non-fault areas.
