Two-phase Transmission Line Fault Analysis of Traveling Wave |
| |
Abstract: | For the traveling wave's fault location in transmission lines, the failure wave analysis has important significance. In this paper, the principle of superposition and the phase-mode transformation method have been used to analyze two-phase fault through resistance. Including amplitude, polarity, refractive index, reflection coefficient of the initial wave, refracted wave and wave reflection. Finally, the corresponding conclusions were given. |
