【Abstract】 Single phase-to-earth fault location for the small neutral earthed system is still a difficult problem to be solved.Wave fault location measure is developing in fault location for grounded system.Wavelets transform theory perfected the traveling wave fault location for the fault location precision and accuracy of small neutral earthed system.This paper preliminarily researches the theoretical fundamentals of traveling wave fault location for the small neutral earthed system,and the application of this location measure for the identification of the first to the ball and the instance of the alternation of overhead lines and cables in the non-direct-grounded neutral system are induced and summarized.更多还原
