Buried Pipeline AC Stray Current and Discharge Method

According to AC interference of the underground gas pipeline, AC interference and defense of long-distance pipeline were discussed. Refer AC interference protection measures of the same industry at home and abroad, a new exhaust stream processing method was summarized, and the effect was good. This paper focused on the sources, harm and form of interference, influence on buried metal pipeline of high voltage transmission line and treatment measures, and the characteristics of various drainage method in practical application was analyzed, thus provide a reference for solving the approximation problem.
