AC Interference Detection and Mitigation Measures for Sunan Refined Oil Pipelines

The AC stray current interference on Sunan refined oil pipeline was tested. It was found that AC interference existed in 5 sections.The disturbance degree and interference sources was confirmed, and the AC voltage fluctuation patterns by difference AC stray current interference sources were obtained. AC interference mitigation measures for Sunan refined oil pipeline were also proposed from simulation experiments in the field and calculation.
