Abstract
A method determines a fault position of a fault on an electrical line. First time stamped current and voltage values are measured at a first line end. Second time stamped current and voltage values are measured at a second line end. The fault position of the line is determined from these measured values. To carry out positioning of a data window for fault location according to the traveling wave principle, after the first current and voltage values are measured at the first line end, the second current and voltage values are determined, which indicate the current or voltage at the second line end. Estimated second current or voltage values are compared with the values measured at the second line end, and the first and second current and voltage values that lie within a period of time established by a first data window are employed to determine a first fault position.
