PCS-9721C Feeder Terminal Unit(FTU)
The Distribution Terminal Unit is a general description of various devices such as a feeder terminal unit and a transformer terminal unit used in distribution feeder circuits.
PCS-9721C is a distribution terminal unit for pole top breakers and overhead lines. Based on NR’s many years of experience in R&D of relay protection devices, monitoring, control, and communication devices, as well as distribution automation, this product is made reliable, stable and more advanced in technology.
The Distribution Automation System is designed with a hierarchy of architecture containing two layers, the master and distribution terminal stations.
The first layer: The Master station, is mainly for monitoring the operation of middle and low voltage lines. the devices and the users of the whole distribution network and controlling the operation of power distribution.
The second layer: The distribution terminal, is mainly for conducting data acquisition, condition monitoring, control and fault detecting. As well as treatment on the middle and low voltage lines, station switch, power distribution transformer and capacitor of the distribution network.
