Abstract
system for non-destructive testing of an overhead energized electrical component. The system has a base, an X-ray source, an X-ray digital imager, and an imager controller. The system also has a removable electrically conductive flexible shield which is adapted to be operatively coupled to, and to encapsulate, at least the base, the X-ray source, the X-ray digital imager and the imager controller so as to form a shrouded system. In a use position, when the shrouded system is positioned adjacent the energized electrical component so as to non -destructively test the energized electrical component, the shield protects at least the base, the X-ray source, the X-ray digital imager and the imager controller from electric fields around the energized electrical component while allowing signal communication between at least the X-ray source and the energized electrical component.
