| Abstract: |
| Three-phase coupling transmission line equation is derived for the overhead transmission lines based on the distributed circuit theory and telegraph equation.The wave parameter relations between two-phase circuit transmission line equation and three-phase coupling transmission line are achieved.DSP(Digital Signal Processor)and single-phase sinusoidal single are applied to get the wave parameters of two-phase circuit transmission line equation,with which the coupling transmis-sion line wave parameters in symmetric three-phase-ground are determined.The voltage measuring circuit is presented.The experimental results on the model transmission lines prove it effective |
