Abstract :
The author presents an accurate algorithm to estimate the location of a transmission line fault. This method uses the fundamental frequency voltages and currents measured at the line terminals. These measurements are not required to be synchronized and the algorithm does not involve any simplifying assumptions. The algorithm is accurate since it solves the sequence network of the equivalent power system directly. The algorithm is evaluated using a 345 kV, 160 mile transmission line model
