Stray current corrosion threatens the steady operation of pipelines slightly or heavily. For safety, it is important to detect and solve the electromagnetic interference problem on pipelines timely. In this paper, a new kind of electric drainage was designed, which could work reliably both in low and high electromagnetic interference. The protection effect of which was investigate in Southwest China, where usually underwent thunder and lightning in rainy season. The results show that diodes circuit, spark gap surge protection circuit and urge protection circuit could cooperate at reasonable switch states. It could discharge the electromagnetism influences in pipelines instantly and the potentials of pipelines could be maintained at an expected scope.
