PGZN-FDR-6000 box-type and PG-FDR hood-type series intelligent distribution network feeder terminals are one of the core products of our company in distribution automation systems. They feature "three-remote" functions (remote signaling, remote measurement, remote control) for short-circuit, overcurrent, ground fault detection, and local data acquisition. They complete the operation and fault monitoring of feeders in the distribution system (mainly monitoring phase-to-phase short-circuit faults and single-phase ground faults) as well as the control functions of corresponding pole-mounted switches.
