Cable Fault Diagnosis System

The F‑XBD100 cable fault diagnosis system is designed for cable lines operating at 6 kV to 35 kV. By installing fault‑monitoring devices at both ends of the cable, it captures and analyzes traveling‑wave signals generated at the moment of a fault, enabling rapid fault location. It can also monitor, provide early warnings, and pinpoint discharge signals caused by abnormal conditions in the cable line, thereby shifting from emergency repair to condition‑based maintenance. Utilizing dual‑end positioning technology, combined with high‑precision current transformers and advanced algorithms, the system accurately locates cable faults, delivers early warnings of line defects, and enhances the stability of line operation.

Medium-voltage carrier scheme

Medium‑voltage power‑line carrier technology, developed by Sino‑Signal, leverages a hybrid networking approach that combines medium‑voltage power‑line communication with wireless connectivity to address signal‑coverage challenges in applications such as distribution‑network control, integrated business‑and‑distribution management, and marketing‑related data collection. By integrating medium‑voltage wireless communication modules, medium‑voltage power‑line carrier modules, signal amplifiers, and other components, this solution achieves multi‑channel data coverage, minimizes the risk of data loss during transmission, and provides robust redundancy, thereby delivering stable, reliable, and real‑time communication for business‑and‑distribution systems.
