摘　　要：小电流单相接地系统选线问题的研究一直没有停止,曾提出多种解决方案并在实践中得到运用。但从现场使用情况来看,选线效果并不理想,普遍存在着误选、漏选的情况,其准确性仍然难以保证。结合马钢实际运行情况,分析、总结影响选线准确性的几个因素和现场施工应注意的问题,并由此对选线原理与发展方向提出展望。The research on line selection in small current grounding system has never stopped, with various solutions having been put forward and adopted. On-site application, however, showed that the results of line selection were far from ideal with lots of incorrect selection and missing selection affecting the accuracy rate. Factors influencing line selection accuracy and attention points for on-site operation were analyzed and summarized in light of the actual operation results at Masteel while the principle and development direction of line selection were prospected.
