Abstract: A method includes detecting a first time, at which a specific partial discharge pulse is detected in an energy transmission cable at a first point at one cable end; detecting a second time, at which the pulse is detected in the cable at a second point at the other cable end; determining a fault location along the in accordance with the first and the second times; determining third and fourth points located in the cable, the third and fourth points delimiting a portion of the cable, including the fault location and none of the other points; detecting a third time, at which a further specific partial discharge pulse is detected in the cable at the third point; detecting a fourth time, at which the further pulse is detected in the cable at the fourth point; correcting the determined fault location in accordance with the third and fourth times.

Abstract: The following steps are carried out for localizing a fault location (6) in a power transmission cable (1): Detecting a first time at which a specific partial discharge pulse is detected in the power transmission cable (1) at a first measurement point (E1) which is arranged at one end of the power transmission cable (1). Detecting a second time at which the specific partial discharge pulse is detected in the power transmission cable (1) at a second measurement point (E6) which is arranged at the other end of the power transmission cable (1). Determining a fault location (6) along the power transmission cable (1), at which fault location the specific partial discharge pulse was generated, depending on the first and the second time.
