Abstract
Electrical inductive apparatus for minimizing power losses in heating of a tank of an electrical inductive structure due to a magnetic field characterized by a tank having a metal wall including openings therein, electrical inductive apparatus within the tank and having terminals thereon, a bushing extending through each opening, conductor means extending through each bushing and connected to the terminals, an electrically conductive shielding member within the tank and disposed between the openings, an electrically conductive member externally of the tank, the shielding member being electrically connected to the electrically conductive member through the openings, whereby the tank is shielded from magnetic fields generated by load currents flowing through the conductor means to minimize power losses and heating of the tank wall.
