摘　　要：当前道路照明接地系统以TN系统为主,TT系统鲜有被采用。笔者试图通过低压、中压系统发生接地故障时产生的故障电压与应力电压,对人员与电气装置的影响与危害,将二者作出定性与定量分析比对,供同行判断与选择。A TN system is currently the dominant earthing system for road lighting,while a TT system is rarely used.The author attempts to qualitatively and quantitatively analyze the impact and harm`of fault voltage and stress voltage generated by earth fault in low⁃voltage and medium⁃voltage systems on personnel and electrical equipment,thereby providing a basis for peers to make judgments and choices.

关 键 词：接地故障 故障电压 应力电压 电击防护 不接地系统 低电阻接地系统 TN系统 TT系统
