摘要： The disclosure relates to a test system for optically checking an electrical line, including a test area for arranging the electric line; a plurality of prisms surrounding the test area; a camera directed at the prisms, which is designed to optically detect the electric line arranged in the test area through the prisms from different sides; a shielding mechanism, the curved inner contour of which encloses the test area and the prisms at least in the radial direction; an air duct, which is at least indirectly connected to a nozzle directed towards the test area and which is designed to apply a cleaning air stream to at least some prism surfaces facing the test area and thereby to entrain dirt particles present on these prism surfaces; and further air ducts opening into an area of the inner contour of the shielding.
