  • Patent number: 11249031
    Abstract: The invention relates to a method for analysing defects in transformer laminations using an inspection system, and to an inspection system (24), wherein the inspection system comprises a detection unit (26), a conveyance device (27) and a processing device, wherein the detection unit includes an optical detecting device (31), wherein the conveyance device is used to continuously transport a plurality of transformer laminations (25) relative to the detecting device, wherein the detecting device is arranged transversely, preferably orthogonally, to a direction of movement of a transformer lamination, wherein a velocity of movement of a transformer lamination relative to the detecting device is measured via a measurement device (40) of the detection unit, wherein an image of a contour of a transformer lamination is captured with the detecting device, wherein images of a transformer lamination are assembled into a combined image of the transformer lamination via the processing device while considering the velocit
