Abstract :
Through a small current grounding system of single-phase grounding to steady state and transient analysis and the existing line selection methods are analyzed and compared, their advantages and shortcomings can be gotten. The line of the selection method in the future was pointed out. The wavelet analysis was introduced to selection methods of faults and the fault lines can be selected in the wavelet analysis method.
