Two-End fault location method usually takes Two-End voltage and current data, Which affect the accuracy of fault location by the current is easy affected by CT saturation. In order to eliminate this effect, article proposes a new method for fault location without the use of current. The new method is only used voltage, without affecting by CT saturation. Using sequence component to construct the equation about the fault distance. In principle, eliminate the non-synchronous angle, not need Two-End data synchronization. Simulation result show that the proposed new method has high precision of fault location,Not easily affected by non-synchronous angle and transition resistance, with good engineering value.
