摘要
A test body (21) for use in determining moisture content in a laminated insulation (4) of a power transformer by means of measuring a dielectric frequency response of the test body is provided. 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 comprises electrodes (23a-b), which are embedded in the laminated structure.
