摘要： A transmission line system, a device for fault protection and computer programs, and a method for locating a fault in a series-compensated two-terminal power transmission line including a compensating bank for providing series-compensation to the transmission line. Different subroutines are utilized for locating faults on line segments from the first terminal to the compensating bank and line segments from the second terminal to the compensating bank. A selection is then made in order to determine a valid result. The subroutines utilize three phase currents synchronized measurements from both terminals and a three phase voltage measurements from one terminal for determining the respective per unit distance to a fault.
