The small current grounding line selection is difficult,using transient zero sequence current fault features to implement the small current grounding line selection is the research focus in the distribution network. In the analysis of small current grounding system of basic failure characteristics,the zero sequence current transient and characteristic band (SFB) within the phase frequency characteristics of the basis,this paper introduces a kind of routing algorithm based on transient zero sequence current characteristics. The application and some problems are analyzed thoroughly,and the results can be used for reference.
