ABSTRACT:
A power transformer is provided with a housing having a plurality of apertures for receipt of a bushing well of a bushing assembly. Each bushing assembly includes a bushing well adapted to be secure in one aperture of the power transformer, and a bushing adapted to be connected to a terminal in the bushing well to permit the conducting of electric current between the bushing assembly and the transformer. The bushing assembly further includes a connector for connecting the bushing conductor to a terminal positioned in the bushing well. The power transformer includes a cap to cover and isolate the unused bushing wells. The cap is preferably a plate structure that attaches to the lip of the bushing well and uses the dielectric formed by the air enclosed by the cap and the bushing well to prevent sparking over to adjacent sites, corona discharge, and accidental contact with a live terminal therein, and to guards against contamination of the bushing well.
