About this file

Written by GovTribe AI · Dec 13, 2024

This is a detailed set of technical drawings and specifications for the supply of Generator Step-Up (GSU) power transformers at Fort Peck Dam in Montana and Oahe Dam in South Dakota. The drawings include specifications for multiple transformer types: Fort Peck requires two 42,000/56,000 KVA transformers with 13.8 KV Delta - 230 KV GRD Y 3-phase configuration, while Oahe requires nine 68,667 KVA transformers with 13.8 KV Delta - 230/132.79 KV 1-phase configuration and one 103,000 KVA transformer with 13.8 KV Delta - 115 KV GRD Y 3-phase configuration.

The drawings provide comprehensive technical details including layout dimensions, wiring schematics, control cabinet configurations, cooling systems, monitoring equipment specifications, and installation requirements. Key components detailed include fiber optic temperature monitoring systems, cooling control systems, protection devices, and auxiliary power systems. The drawings also specify mounting requirements, vault configurations, and temporary storage locations at both dam sites. The solicitation number is W9128F25R0002 with a date of January 2025, managed by the US Army Corps of Engineers Omaha District with support from the Hydroelectric Design Center in Portland.

GENERAL NOTES:

RESULTING CONTAINMENT VOLUME: 7,779 GAL.

CRIBBING: 2 x (4' X 20' X 1') x (7.48 GAL/CU.FT.) = -1,197 GAL.

BERM: (40' x 20' x 1.5') x (7.48 GAL/CU.FT.) = 8,976 GAL.

OIL CONTAINMENT BERM VOLUME:

OIL CONTAINMENT BERM MINIMUM VOLUME: (7,000 GAL)(1.10) = 7,700 GAL

TRANSFORMER MAXIMUM TOTAL OIL VOLUME (EACH): 7,000 GAL.

OIL CONTAINMENT BERM VOLUME CALCULATIONS (BASED UPON EXAMPLE BERM):

THE TRANSFORMER TOTAL OIL VOLUME.

THE OIL CONTAINMENT BERM IS TO BE SIZED TO CONTAIN A MINIMUM OF 110% OF

OIL-FILLED WHILE IN THIS CONTAINMENT BERM IN TEMPORARY STORAGE.
