About this file
This is a detailed design document for spare transformers at the Little Goose Lock and Dam, part of the Lower Snake River project for the US Army Corps of Engineers Walla Walla District. The document provides comprehensive technical specifications for a 500 kV Generator Step-Up (GSU) transformer with a 164,000/218,666 kVA rating, designed for ONAN/ONAF cooling. Key specifications include a maximum weight of 591,500 pounds, maximum oil quantity of 15,539 gallons, and a temperature rise of 65°C. The transformer will feature multiple cooling fans, hot-dip galvanized radiators, and a nitrogen blanket or constant oil pressure preservation system. The design includes detailed schematics for control and power cabinets, current transformers, annunciation systems, and external connections, with provisions for future electronic monitoring and diagnostic equipment.
