CAFS: Advanced MV Cable Alerting and Fault Spotting by China's Leading Suppliers and Factory

CAFS, developed in China, is a state-of-the-art monitoring system specifically designed for 6kV to 110kV power cables. This innovative solution features a layered distributed structure, utilizing advanced digital technologies to withstand harsh operational environments. CAFS continuously monitors the insulation status of power cables and analyzes transient traveling waves in grounding wires in real-time. As a reliable tool from a leading factory, it enables early detection of insulation faults, facilitating timely predictions to prevent unexpected power outages caused by cable failures. This proactive approach significantly enhances power supply reliability, making CAFS an essential choice for suppliers seeking quality assurance in their electrical infrastructure.

Product Detail

Functional Features

New monitoring methods: High-frequency digital signal spectrum comprehensive analysis method and dual end measurement method.

Fault location: Using the principle of traveling wave distance measurement, precise fault location can be achieved, with a fault distance measurement accuracy of ± 2.5 meters.

Fault line selection: Using the principle of traveling wave line selection, fault circuit line selection is carried out for cable insulation.

Circulation monitoring: Real time monitoring of the insulation condition of the outer sheath of the line. By using digital spectrum analysis methods, the capacitive current, resistive current, and fault arc current of the cable are calculated separately, and the circulation curve is drawn. Fault alarms are given for cable lines with abnormal outer sheath insulation.

Fault warning: Three-level warning based on cable operation status.
