1. A method for detecting deformations of high voltage and/or medium voltage cables and/or cable components, comprising following steps:
a) at a first point of time, capture and store a first set of 3-dimensional, 3D, surface geometry measurement data of an area of interest of a surface of the cable or cable component,
b) at a second point of time, capture and store a second set of 3-dimensional, 3D, surface geometry measurement data of said area of interest of said surface of the cable or cable component by moving a 3D surface scanner about the cable over the area of interest, and
c) compare the first and second sets of captured 3D surface geometry measurement data to determine changes that have occurred in the cable or cable component between the first and second points of time, where changes indicate a deformation of the cable or cable component.
