Dry testing of non-conductive liners

The invention generally relates to dielectric testing of non-conductive bucket liners for mobile aerial man-lift equipment where two conductive shaped materials are placed on opposite sides of a dielectric material being tested. High voltage is applied to one of the conductive materials while a ground lead is attached to the other. Electrical current is measured from the grounded conductive material to identify any breakdown of the dielectric properties of the material being tested.
