# 小电流接地系统单端行波故障定位新算法A New Arithmetic of Single-Port Wavelet Fault Location for Small Current Grounding System

The single-port wavelet fault location has the merits that location speed is fast, it is not need inspect lines, low cost and may locate many times, so it is one of the effective methods of single-phase grounding fault location of small current grounding system. But its location precision is influenced by many factors, especially the speed precision of the wavelet. On the basis of wavelet theory, it proposes a new arithmetic of single-port wavelet fault location for small current grounding system which not influenced by the speed of wavelet. The result shows that the arithmetic is correct and the simulation result shows that the precision of this arithmetic is better than the traditional single-port wavelet fault location method.
