SP3000 Distributed Diagnosis and Early Warning System for Transmission Lines
The monitoring device is installed directly on conductors, capturing both traveling wave components and power frequency signals near fault/discharge points during line abnormalities at high voltage side. Leveraging intelligent diagnostic algorithms, it enables automated rapid identification of diverse fault types, supporting abnormal discharge early warning, fault section localization, pinpoint fault location tracking, root cause analysis, and lightning characteristic monitoring. This innovation overcomes limitations of traditional methods, such as poor performance with high-impedance earth faults, limited adaptability to complex line structures, inability to identify fault origins, substantially reducing O&M costs while accelerating power restoration times. It significantly enhances fault handling efficiency and elevates smart monitoring capabilities for transmission lines.
