1. , the present invention " a kind of method of measuring distance of transmission line fault ", this method is to utilize inductance, resistance, electronic switch to obtain L, R according to the characteristics of transmission line and transmission line malfunction by Measuring Time constant τ

  • =L/R.Calculate the transmission line malfunction distance with L like this.Calculate the resistance of transmission line malfunction with R.Produce the τ

    that utilizes aperiodic component when loop current is AC power, produce the τ

    that utilizes electric current to rise when loop current is DC power supply by index.
