Substation and electric systems equipment 3D laser scanning

Three-dimensional laser scanning of power equipment and facilities of electric power systems (power plants and substations) is a new high-tech activity of the 3D laboratory of the <;<;Automated Power Systems>> department of the Ural Power Engineering Institute, UrFU. Laser scanning allows providing full reproduction of topographic and geometric data of the power facility. The implementation of reverse engineering becomes possible on the basis of 3D scanning. Laser scanning of power facilities allows achieving the priority goal of obtaining a three-dimensional primary digital CAD-model and its drawings with high accuracy needed to meet the challenges of designing, construction, quality control, diagnostics and other engineering tasks. This paper presents in detail the methods and stages of laser scanning by the example of simulating (CAD-model creation) a 110/20 kV 40 MVA step-down power transformer.
