The invention provides a small current grounding system single phase earth fault traveling wave line selection and distance measurement apparatus which comprises a signal conversion plate, a high speed acquisition plate and a central management machine. The signal conversion plate converts bus zero sequence voltage and line current to 0 to 10 volts voltage signal after isolation. The high speed acquisition plate connecting with the signal conversion plate finishes the conversion from analog signal to digital signal, carries out high speed acquisition and caching, receives a synchronization time setting signal simultaneously, and marks data with absolute marker. A digital signal processor (DSP) of the high speed acquisition plate calculates whether the zero sequence voltage exceeds a starting set value or not, wherein, if so, line fault happens. The DSP automatically searches and calculates a tip size and direction of traveling wave, and outputs line selection result through a switch output plate connecting the high speed acquisition plate. Simultaneously wave recording is started to record fault data which is transmitted to the central management machine through a high speed bus. According to the wave recording data, the central management machine automatically searches initial wave tip of the fault line and time of fault point reflection wave tip, and calculates distance of the fault point. Finally, fault data and fault report are published through a WEB SERVER platform.
