Abstract
An electrical transformer includes a tank containing transformer fluid and a transformer core and winding subassembly located in the transformer fluid within the tank. The electrical transformer also includes a mechanism for varying the dynamic pressure of the transformer fluid within the tank during electromagnetic operation of the transformer core and winding subassembly to cancel out (or reduce) noise-causing vibrations in the transformer fluid which come from the operating transformer core and winding subassembly. Preferably, the electrical transformer further includes an active mount subassembly.
