High-Voltage Cable Outer Sheath Monitoring System
The monitoring system integrates a power frequency circulating current acquisition unit, enabling scheduled collection and uploading of phase-to-ground current data for precise measurement of ground loop currents. By analyzing numerical ranges and trend patterns, operators gain insights into cable operating conditions. When abnormal ground loop currents are detected, the system automatically triggers alarm notifications. This technology replaces traditional manual periodic circulation inspections, significantly reducing on-site labor intensity while enhancing maintenance efficiency.
