YHK41 Three Remote Box FTU

Overview

? The overhead "three remote" terminals, also known as feeder terminals, are distribution terminals installed at overhead line towers and other locations in the distribution network. They cooperate with switches to monitor the operation of the real-time distribution system, complete functions such as data collection, line protection, switch control, and communication with the main station, providing technical support for real-time monitoring and scheduling of the distribution network. It can cooperate with the main station to achieve centralized FA function, and can cooperate with upper and lower level terminals to achieve distributed FA function.
