Abstract
The fault location of a fault on a line of an electrical energy supply network is determined. First and second current and/or voltage values are measured and provided with a timestamp at the line ends of the line. Following the occurrence of a fault, the timestamped first and second values are used to determine the fault location. Profiles of travelling waves propagating along the line towards the line ends when the fault occurs are determined from the timestamped first and second values at both line ends. The fault location is defined from the profiles of the travelling waves from a time difference with which the travelling waves arrive at the two line ends. The time difference is derived from a pattern comparison of the profiles of the travelling waves determined for the line ends.
