Abstract
Size constraints imposed by riveting of the laminations of a sensing core transformer that cost constraint imposed through the use of adhesive in assembling laminations together in a sensing core along with the use of additional fasteners are eliminated through the use of two lamination assemblies, that are interference fitted at complementary surfaces to form a series of lamination assemblies to which a coil assembly may be applied. Individual laminations may be held together by stake holding structure.
