Hitachi Energy is a world leading company in the production and installation of power transformers and the quality of their services is of the utmost importance. The majority of the company's current quality control methods are performed manually, the purpose of this study is to identify potential areas where the use of 3D-scanning technology as a method for quality control has potential, making use of interviews, literature studies and document analysis to do so. Further the study wishes to outline the specific methods that could be used to increase the efficiency of the production and present the steps that would be required for these methods to be implemented effectively. The results revealed that both the active core and final assembly processes currently face issues. The active core assembly with specific aluminum pipes that often differ from the specified tolerances. Most of these problems come from external suppliers and get noticeable when they arrive at the active core assembly. The final assembly faces issues with the lowering down of the active core into its container. A process that can vary drastically in the time it takes while simultaneously being a very time sensitive process. The study proposes three methods as solutions to these problems. An initial control of the aluminum pipes after delivery with FARO:s Quantum Max ScanArm and CAM2 Software. As well as a simulated lowering down of the active core, making use of FARO:s Focus Laser Scanner and the software program SCENE. Lastly, a more general use of 3D-scanning for quality control. It is concluded that committing to an investment is required to reach further results.
