Laser scanning of cable and cable accessory components subjected to mechanical loads and elastic or inelastic deformation

Abstract

A method for detecting deformations of high voltage and/or medium voltage cables and/or cable components, include at a first point of time, capturing and storing (302) 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. The method also incudes, at a second point of time, capturing and storing (304) a second set of 3-dimensional, 3D, surface geometry measurement data of an area of interest of a surface of the cable or cable component by moving a 3D surface scanner about the cable over the area of interest. The first and second sets of captured 3D surface geometry measurement data is compared to determine changes that have occurred in the cables or cable components between the first and second points of time, where changes indicate a deformation of the cable or cable component.
