| Abstract: | Using the transmission line equivalent model of metallic pipelines.the effects of the earth-returned currentfrom an HVDC toroidal grounding electrode buried in the homogencous soil on underground metallic pipelines and cableswere analysed in this paper. The influence of some geometrical factors.such as electrode depth,distance to the electrode.etc. on corrosion of the pipelines were emphatyically investigated and the relevant conclusions obtained. |
