The results of an analysis of the change in the pole voltage when there are short circuits in the middle of the cable and in the middle of the overhead parts of a cable overhead line without a loss of dc transmission, to determine a method of detecting the damaged part, are presented. The operating principles of the main and standby protection of the dc transmission line are considered. Block diagrams of the functioning of these protections are presented. It is shown that, to increase the reliability of dc transmission, the action of the line protections must be coordinated on the basis of priority conditions.
