Abstract
The principle of combined cathodic protection for internal and external pipelines of stations is introduced. By analyzing the distribution of cathodic protection current and potential fluctuations after jumping insulation joints, the effect of the combined cathodic protection method on the mitigation of dynamic direct current (DC) interference is evaluated, and the influence of the grounding resistance of grounding grids in stations on the cathodic protection is discussed.
