Fault Location in High Voltage Transmission Lines Using Resistance, Reactance and Impedance
This paper presents two methods for on-line computation of dynamic fault location in HV transmission lines using three means; resistance, reactance and impedance. These methods can be used for dynamic distance protection of the transmission line.
