With the development of power technology and the improvement of reliability of power supply of power user requirement, small current grounding system become the main grounding mode of distribution network. Small current grounding power system fault line selection is always one of the puzzles in medium voltage distribution network relay protection technology, until now it has not been solved satisfactorily. In this paper, we summary and review the algorithms of small current fault line selection, review domestic and abroad extensive works and achievements in this field in recent years. Summarizing the fault line selection methods based on the steady state information and transient information and analyzing the advantages and disadvantages of various algorithms, at the same time, we study the difficulties of future research and the directions of research.
