摘要
There is provided mechanisms for travelling wave protection of a transmission line. A method includes performing high-pass filtering of a current and/or voltage measurement of a transmission line so as to detect fault-caused high-frequency components of the current and/or voltage measurement. The method includes providing a result of the high-pass filtering as input to a trip decision maker performing travelling wave detection.
