Attachment 3 - Transformer Locations.pdf

This document contains electrical distribution system diagrams showing transformer locations and electrical infrastructure at Peterson Air Force Base. The diagrams include a detailed grid-based layout showing the primary electrical distribution system with color-coded feeder lines (PSS feeders in various colors like green, blue, orange and red) and transformer locations marked with their respective capacities (ranging from 10kVA to 3300kVA). The drawings include symbols for three-phase and single-phase pad mounted transformers, pole mounted transformers, pad mounted switchgear, junction boxes, reclosers, manholes, and overhead/underground lines.

The diagrams are highly detailed engineering drawings with matchlines connecting multiple sheets (numbered from 112 to 909) to show the complete base electrical infrastructure. Key features include transformer identification numbers, switch locations, building numbers, street names, and detailed legends explaining all symbols and notations. The drawings were developed based on field walkthroughs of the primary distribution system and include notes about potential errors or changes that may have occurred since documentation. This appears to be a reference document to help locate and identify electrical infrastructure components across the base.
