Research on high-frequency acquisition and processing system for pipeline under extreme electromagnetic environment

With the increasing number of extreme weather events, the risk of pipeline damage from lightning strikes and power line faults in public areas has escalated. Once a large current flows into the pipeline, it may cause coating breakdown and metal fusion, and even lead to secondary hazards such as equipment failure, fire, and explosion. This paper presents a high-frequency detection and processing system designed specifically for pipelines. It is capable of detecting strong current pulse moments in extreme electromagnetic environments, and rapidly collecting and processing pipeline interference parameters to assess pipeline damage. Field tests show that the system has excellent synchronization, high acquisition frequency, low signal distortion, fast response speed, and has significant engineering application value.
