Design of fault location system in power transmission line based on single-ended traveling wave

SANG Yaping,ZHAO Yulin(Engineering College,Northeast Agricultural University,Harbin 150030,China)  
Fault location equipment provides a safe running environment for electrical system.In this paper,based on location principle of single-ended traveling wave,hardware starting circuit was designed to detect fault.High speed,high accuracy A/D data conversion,and high speed DSP were adopted to deal with data and extract traveling wave head,and achieved a fast,accurate fault location of transmission line.
