About this file
These are technical engineering drawings for a Westinghouse single-phase power transformer, specifically for the U.S. Army Corps of Engineers' Lower Monumental, Little Goose, and Lower Granite Lock and Dam project. The transformer has a rating of 82,000/109,334 kVA, with a high voltage of 500,000 grounded wye/288,675V, and secondary voltages of 13,200V. The detailed drawings include comprehensive specifications for the transformer's mechanical and electrical components, such as base plate details, bus duct flange specifications, lifting centers, shipping dimensions, and schematic wiring diagrams. The documents cover multiple aspects of the transformer, including its foundation, pad layout, electrical connections, and structural details, with drawings prepared by Westinghouse Electric Corporation in Muncie, Indiana in late 1975.
The technical documentation provides extensive information on the transformer's physical characteristics, including its complete center of gravity, horizontal and vertical jacking centers, shipping dimensions, and critical installation notes. The drawings include detailed views of the transformer's base plate, bus duct connections, jack lug details, and wiring schematics for control cabinets and stationary panels. The contract number is DACW68-75-C-0160, and the drawings are part of a comprehensive set of engineering specifications for the power transformer, with multiple sheets covering different aspects of the equipment's design, installation, and technical specifications.
