Abstract: A transformer having an insulation system is presented. The transformer includes a magnetic core having an opening. Also, the transformer includes a plurality of primary windings disposed extending through the opening of the magnetic core. Further, the insulation system includes a first insulation substantially encapsulating the plurality of primary windings and impregnating spaces between the plurality of primary windings, and a second insulation disposed around the first insulation, where the second insulation has at least one of a predetermined dielectric strength and a predetermined thickness configured to isolate a first voltage signal in the plurality of primary windings from the magnetic core.
