The SP3000 Cable Monitoring System is a cutting-edge platform for real-time fault diagnosis, early warning, and precise location of issues within high-voltage and medium-voltage power cable networks. Designed to ensure grid reliability, it addresses challenges such as undetectable insulation aging, hidden discharge, and fault current tracing with accuracy up to 0.2% × cable length + 5m.

• Real-time monitoring of cable discharge events (traveling wave-based)
• Ultra-wide sensor bandwidth:

Current: 0.1kHz–10MHz

Traveling wave: 1kHz–20MHz

• Fault positioning accuracy: ≤0.2% × L + 5m
• Simultaneous early warning + fault classification

Installation Guidelines

• 1 cable MT set = 1 data acquisition unit + 9 sensors
• For cable lines ≤10km: install 1 set at each end
• For >10km: add 1 set every 10km + each long branch
• Supports hybrid systems (overhead & cable integration)

 Functional Highlights

• 01. Section Position Identification Pinpoints the fault section even in complex/mixed lines to clarify unit responsibility.
• 02. Fault Location Uses traveling wave polarity + amplitude for exact fault pinpointing (within 5m accuracy).
• 03. Early Warning System Detects abnormal discharges before they escalate into trips, enabling predictive maintenance.
• 04. Multi-loop Monitoring Supports up to 12 cables simultaneously, enabling large-scale system integration.
• 05. AI Visual Integration (Optional) Snapshots fault conditions in real-time and automatically alerts operators via the backend.
