Abstract: A device (10) for measuring space charge in a high-voltage direct current electric cable includes a DC voltage source (12), a voltage step generator (14), a first electrode (16) connected to the DC voltage source (12) and to the voltage step generator (14), a second electrode (18) that is grounded, a piezoelectric sensor (20) connected to the second electrode (18), an electrical-signal amplifier (22) connected to the piezoelectric sensor (20), and at least one specimen (24) of the electric cable placed between the first and second electrodes (16, 18) and including a cut of the cable made to a predetermined depth in the electrical insulation system of the cable. The amplitude of the signal measured at the output of the amplifier (22) is related to the charge density in the specimen (24) and the delay related to the distance of the charges from the piezoelectric sensor (20) giving the position of the charges.

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.

Abstract: A method is provided for determining a quality of a surface of a cable, a part of a cable or an accessory for a cable. 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. In an analysis unit, a continuous 3D surface geometry measurement is created of the area of interest by processing measurement data from the 3D surface scanner. The processing includes identifying anomalies in the continuous 3D surface geometry and inspect the captured 3D surface geometry measurement data to discover sub-areas with increased probability for faults. A quality report for the scanned surface is provided.

Abstract: A method and system is provided for inspecting damages to high voltage and/or medium voltage cables or cable components. The method and system captures and stores a set of 3-dimensional (3D) surface geometry measurement data of the 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 from step a) is inspected to evaluate if any damages are present, and if the inspection reveals a damage, a section of the cable body is removed. Steps a) to c) can be repeated until no damage is revealed and a 3D map of the damage can be provided.
