| Abstract: | tray current problem on Dalienhe-Harbin gas pipline arising from direct current transit system could be Very severe. By providing a metalic bond between the pipeline and the negative bus of the transit system,the reverse current flow could be prevented from. Various type of rectier discs (or diodes) are used in this bond. |
