Abstract
A sealed core-coil assembly in a submersible transformer includes a coil assembly having an inner coil with inner, outer, upper, and lower surfaces, and an outer coil with inner, outer, upper, and lower surfaces, a core assembly including a core window and core column of a magnetically-permeable material, the core column and core window having inner side surfaces, and an expandable sealing member including an inner cavity that is fillable or evacuatable so that a compliant insulation material is positioned in the inner cavity to block passage of water and prevent the formation of a loop of water, which otherwise would act like an electrical short in a submerged transformer.
