BHDJ-300 Cable Fault Precision Locating Device

New Products / New Technology

The system employs high-speed transient traveling-wave fault location technology to enable real-time, online monitoring of the operational status of distribution network cables, providing early warning and rapid, precise fault localization, while also facilitating fault‑line selection for feeder branch circuits.

BHDJ-500 High-Voltage Cable Online Monitoring and Fault Location Device

New Products / New Technology

The system is primarily designed for comprehensive condition monitoring of 66 kV to 500 kV high- and extra-high-voltage cables, including both the cable body and cable terminations; it provides an integrated solution for monitoring cable operating conditions, issuing early warnings of abnormal states, and performing fault diagnosis.

BHDJ-701 Overhead Distribution Line Fault Locator (Non-Contact Type)

New Products / New Technology

The system monitors the operational status of overhead distribution lines and supports live‑line installation. It captures transient traveling‑wave signals during line operation and uploads high‑speed A/D‑converted digital data to the system backend. The backend employs proprietary algorithms for analysis and processing, enabling real-time online monitoring of overhead lines. The monitoring device leverages advanced dual‑ended traveling‑wave fault location technology to achieve precise fault‑point localization, providing a reliable basis for identifying faults on overhead distribution lines.
