Primary conductor for a transformer

A transformer includes a core having an aperture formed therein and a conductive bar extending through the core. The aperture in the core has a centroidal axis The conductive bar includes: a first surface extending generally parallel to the centroidal axis, a second surface opposite the first surface and extending generally parallel to the centroidal axis, the first surface being closer than the second surface to said centroidal axis. The conductive bar also includes means for diverting electrical current flowing through the conductive bar towards said first surface.
