Abstract
An electrical insulator coated with electrically insulating material is disclosed. An electrically insulating material is applied on a primer coat, in which the uniformity of the applied primer coat can be checked in a comparatively simple manner. A fluorescent material is dissolved in the primer solution before being applied to the component. Once dry, the primer coat is exposed to ultraviolet light, which causes the fluorescent material to fluoresce. Points on the surface of the component where the primer defectively coats the components are optically detected from the absence of fluorescent material. Primer is then reapplied to these points.
