| Abstract: | The traditional transmission line fault location device is installed in the transformer substation.Through the current transducer,the high-frequency traveling wave will attenuate and the bandwidth will be narrowed,these will affect the traveling wave front detection.So the paper presents a new distributed transmission line fault location device,set several checkpoints along the transmission line and measure the high-frequency traveling wave by Rogowski coil.According to the difference of the transmission speed of traveling wave zero mode and aerial mode component in the transmission line earth-fault,locate the fault point by the time difference between the initial wave heads of the aerial mode and zero mode.This method can remove the affection of the wave speed and improve the accuracy of the fault location. |
