It features remote control, remote signaling, and fault detection capabilities, and communicates with the main station of the distribution automation system to provide real‑time information on the operation of the distribution system and various parameters—including switch status, power parameters, phase‑to‑phase faults, ground faults, and fault‑related parameters—while executing commands issued by the distribution main station to regulate and control distribution equipment. This enables functions such as fault location, fault isolation, and rapid restoration of power to non‑faulted areas.

Overhead External Signal-Type / Transient Characteristic-Type Remote Fault Indicator JYW/Z-HD

Currently, most distribution networks employ small-current grounding systems. When a single-phase ground fault occurs in such systems, the fault current is low and the fault characteristics are complex, making line selection and fault location for single-phase ground faults a persistent technical challenge in distribution network operation. Accurately identifying the grounded line and pinpointing the faulted section while maintaining continuous power supply remains a critical issue. The signal source detection method (asymmetric current) for detecting single-ground faults operates on the principle of leveraging the unique characteristics of single-phase ground faults in small-current grounding systems—specifically, by analyzing the distinctive features of asymmetric current signals generated on the faulted line to achieve both line selection and fault location.
