feeder remote terminal unit,
dsp digital signal processor
remote controlling power distribution feeder terminal unit detecting fault and transmitting switch status data by gprs/3
This is a new HV switch control device 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. It boasts of 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, widely applied to the radiant and ring network power supply systems to help the systems identify transient and permanent line faults, eliminate the impact of transient line faults automatically, isolate the permanent fault segments to avoid prolonged power failure in large area, and automatically recover the power supply in fault-free areas, so as to realize the automation of power distribution network in a economical and practical way.
