| Abstract: |
| For the performance test methods of traveling wave fault locating device for transmission line，the influencing factors on the recept of traveling wave by fault locating device are analyzed. The whole-process simulation of traveling wave propagation is proposed. The characteristics of traveling wave propagation through current transducer is described with a two-port network，which is applied to realize the whole-process simulation of traveling wave propagation，including transmission line fault，current transducer transferring，secondary cable transmission and secondary load simulation. The simulative waveform is similar to the site recorded one. The whole-process simulation of traveling wave propagation is accomplished for the engineering application and the site test of designed traveling wave fault locating device for DC transmission line is completed. |
