Abstract
A method and a system is provided for inspecting surfaces and/or interfaces of high voltage and/or medium voltage cable components. The method includes capturing and storing a 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 captured 3D surface geometry measurement data are inspected to determine smoothness of the scanned surface, and the smoothness is compared with threshold data to provide a quality report for the scanned surface.

A method for inspecting surfaces and/or interfaces of high voltage and/or medium voltage cable components, comprising:
- a) capture and store a set of 3-dimensional, 3D, surface geometry measurement data of an area of interest of a surface of the cable component by moving a 3D surface scanner over the area of interest, wherein a fixture is arranged around the surface to be scanned for capturing the 3D surface geometry measurement data, said fixture comprising a plurality of positioning markers,
- b) inspect the captured 3D surface geometry measurement data from step a) to determine smoothness of the surface scanned by the 3D surface scanner, and
- c) compare the smoothness with threshold data to provide a quality report for the surface scanned by the 3D surface scanner.
A system for inspecting surfaces and/or interfaces of high voltage and/or medium voltage cable components, the system comprising:
- a non-contact surface scanner, for capturing at least one set of 3D surface geometry measurement data of an area of interest of a surface of the cable component by moving the non-contact surface scanner over the area of interest,
- a fixture for arranging around the surface to be scanned for capturing the 3D surface geometry measurement data, said fixture comprising a plurality of positioning markers,
- a memory unit for storing multiple 3D surface geometry measurement data of the area of interest,
- a processor connected to the non-contact surface scanner, configured to inspect the captured 3D surface geometry measurement data to determine smoothness of the surface scanned by the surface scanner, and
- compare the smoothness with threshold data to provide a quality report for the surface scanned by the surface scanner.
A method for inspecting surfaces of parts and/or equipment for manufacture of high voltage and/or medium voltage cable components, comprising:
- a) capture and store a set of 3-dimensional, 3D, surface geometry measurement data of an area of interest of a surface of the cable component by moving a 3D surface scanner over the area of interest, wherein a fixture is arranged around the surface to be scanned for capturing the 3D surface geometry measurement data, said fixture comprising a plurality of positioning markers,
- b) compare the captured 3D surface geometry measurement data from step a) with a previously stored set of 3D surface geometry measurement data or a 3D drawing of the cable component, and
- c) record any differences in a quality report for the inspected surface.
