METHOD OF QUALITY INSPECTION OF A JOINT OF A POWER CABLE

A method of performing a quality inspection of a vulcanized joint of a power cable during manufacturing of the vulcanized joint, the method comprising: a) obtaining, from a laser scanner, measurements of an outer surface of an inner semiconducting layer provided over a conductor joint which joints conductors of two power cable sections, and of a transition area between the outer surface and outer surfaces of a respective inner semiconducting layer of the two power cable sections, b) obtaining, from a laser scanner, measurements of an outer surface of a tapering section of an insulation layer arranged around a respective one of the inner semiconducting layers of the two cable sections, c) processing the measurements obtained in step a) and in step b), the processing involving generating one or a respective 3-d model of the outer surfaces and evaluating an outer surface quality of the outer surfaces based on the one or more 3-d models, d) presenting a conclusion regarding surface quality based on the evaluation, e) obtaining, from a laser scanner, measurements of an outer surface of a joint insulation arranged around the inner semiconducting layer that is provided over the conductor joint, the joint insulation having been provided over the inner semiconducting layer provided around the conductor joint after step d), and f) processing measurements obtained from the laser scanner in step e), the processing involving determining an insulation thickness or an outer diameter of the joint insulation, and g1) presenting the insulation thickness or outer diameter, and/or, g2) evaluating the insulation thickness or outer diameter, and presenting a conclusion regarding the insultation thickness or outer diameter based on the comparison.
