CAFS for MV Cable Alerting and Fault Spotting - Reliable Solutions from China Suppliers and Factory for Power Cable Monitoring

CAFS is an innovative solution designed by leading China suppliers, specifically engineered for 6kV to 110kV power cables. Our state-of-the-art system features a layered distributed architecture that incorporates advanced digital technologies, making it ideal for harsh operational environments. CAFS continuously monitors the insulation status of power cables in operation and performs real-time analysis of transient traveling waves in power cable grounding wires. This enables the early detection of insulation faults, allowing for timely predictions and interventions to prevent outages caused by unexpected cable failures. By choosing our factory-manufactured CAFS, you significantly enhance power supply reliability and maintain critical operational efficiency.

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.

Products Advantage

Partial discharge monitoring, signal acquisition and transmission: On-site acquisition and conversion into optical signals, without interference and attenuation, ensuring accuracy from the source.

Lightning protection and anti-interference technology: Exclusive patent of Enrely, validated in the market for nearly 10 years with significant results.

Sampling frequency: Hardware and software sampling frequency is only 100MHz.

CAFS coverage: No monitoring blind spots.
