A method for handling failure of a TSN communication link in a TSN network. The method is performed by a control node and includes estimating requirements for TSN communication for end-points based on application parameters, input/output requirements, and application requirements, wherein each end-point is capable of communicating over a TSN channel and a non-TSN channel in the TSN network using one and the same network interface. The method includes obtaining an indication of a failure of a TSN communication link in the TSN network between two of the end-points. The method includes performing self-healing of the TSN communication link.

A method can be used to determine a fault location in a power transmission line that connects a first terminal with a second terminal. Parameters associated with travelling waves are detected from measurements carried out at the first and second terminals. The parameters include arrival times of first and second peaks of the travelling waves at the first and second terminals respectively, and rise times of the first peaks of corresponding travelling waves. A first half, a second half, or a mid-point of the power transmission line is identified as having a fault based on the parameters. The fault location can be estimated based on the arrival times of the first and second peaks of the travelling waves detected from measurements carried out at the first and second terminals, a velocity of propagation of the travelling wave in the power transmission line, and/or a length of the power transmission line.
