Distribution Feeder Terminal Unit FTU YM-FDR700

A 32-bit high-performance processor and an external AD chip meet domestic design requirements. It can be configured to operate in multiple modes, including centralized feeder automation, local feeder automation, and protection with reclosing; it supports traveling‑wave fault location for distribution networks and distributed energy resource–grid boundary detection. For small‑current grounding systems, the accuracy of single‑phase ground fault handling exceeds 95% across the entire product line. Both the core hardware and software platform are entirely developed in‑house.
