摘要： A method and an apparatus for fault detection in a mixed configuration power transmission line (10) comprising a plurality of sections (11, 12, 13) arranged between one end (S1) of the transmission line (10) and the other end (S2) of the transmission line (10) and comprising at least one overhead line section (11, 13) and at least one cable section (12) are disclosed. Based on a comparison travelling wave voltage or current time derivatives at the one end (S1) and the other end (S2) of the power transmission line (10) with selected threshold values, it is determined if there is a fault occurring in at least one cable section (12) of the power transmission line (10). Embodiments of the present invention utilize amplification of travelling wave voltages and/or currents which may occur at junctions (14, 15) between a cable section (12) and an adjacent overhead line section (11, 13) in determining if the fault occurs in a cable section (12) of the power transmission line (10).
