Control Box-Feeder Terminal Unit
The feeder terminal unit(FTU) is a new HV switch control device of control cabinet enclosures equipped with both the imported DSP high-speed sampling chips and the high-performance ARM chips, and can fast and stably finish the monitoring on the switch.
Industrial feeder remote terminal unitby our electric power equipment company has such functions as the protection, measuring, controlling, monitoring, communication, remote control, and so on and features high integration level, flexible configuration, and user-friendly interface. Electrical control cabinet are widely applied to the radiant and ring network power supply systems.
FTU outdoor control electrical control box can help the systems identify transient and permanent line faults. Outdoor control box eliminate the impact of transient line faults automatically, isolate the permanent fault segments to avoid prolonged power failure in a large area, and automatically recover the power supply in fault-free areas, so as to realize the automation of power distribution network in an economical and practical way.
