Abstract
A test body for use in determining moisture content in a laminated insulation of a power transformer by measuring a dielectric frequency response of the test body. The test body has a laminated structure of the same material as the laminated insulation, and has a shape and a size to obtain moisture content characteristics that resembles the moisture content characteristics of the laminated power transformer insulation. The test body further includes electrodes, which are embedded in the laminated structure.
