High-Voltage Cable Fault Early Warning and Precise Positioning System (SP3000)
The monitoring system utilizes online detection technology to capture traveling waves generated by latent discharge activities and fault-induced discharges propagating bidirectionally along the cable. It accurately locates the positions of such discharge points, enabling early warning for potential hazards in the cable line and rapid online fault location.
