Firstly, the importance of cable line in our daily life is introduced in this paper, if partial discharge happens, the electric power system will have great problems on operating; then, The inducements of PD on cable line, the specific operation and implementation steps is analysed. Meanwhile, this paper compares with some common methods of PD detection and summarize the advantages or disadvantages of each method in specific environment. Finally, through the paper we can know that each method has its own superiority to get the location of PD in different environment or situation, however, no perfect method is founded. So, we need a deeper study to continue the research on Partial Dischar
