The electronic-sensor universal feeder terminal can realize on-site feeder automation without relying on a distribution automation master station or communication system. Through advanced short-circuit/ground-fault detection technology, voltage-loss adaptive delay reclosing, and self-adaptive control logic, it automatically adapts to radial, multi-section, and multi-connection distribution network topologies. It achieves on-site fault section location, isolation, and restoration for single-phase ground faults, isolates the fault zone via reclosing, and restores power supply to non-fault zones.
