Abstract
The electrical inductive apparatus including non-magnetic flux shields constructed of strips of highly electrically conductive material which are arranged to form a continuous loop around the core window. The shields are disposed parallel to the laminations of the magnetic core and adjacent the top and bottom surfaces of the core. Current induced in the shields by the leakage flux from the windings produces an opposing flux which prevents substantially all of the winding leakage flux from entering the magnetic core.
