Analysis of Single-Phase-to-Ground Fault Generated Initial Traveling Waves

2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005
Analysis of fault generated traveling waves is the base to implement traveling waves based protection and fault location. However, the structure at fault point is not asymmetrical under single-phase to ground fault condition in multi-phase power system, so that traveling waves analysis method of single circuit can not be applied.
