Research on Stray Current Interference Detection and Drainage Protection of An Oil Pipeline
The oil pipeline crosses and parallels the subway running line,the pipeline potential drifts,the power off potential is positively shifted,and the pipeline disturbed by stray current will be in an unprotected state for part of the time.After the drainage protection measures were taken for the pipeline in the interference section,it was found that the potential fluctuation range of the pipeline was reduced and the cut-off potential was negatively offset by monitoring the pipeline potential.The stray current interference of the pipeline is effectively eliminated and suppressed,and the pipeline is operated in a cathodic protected state for all times.
