Elect One Line 11x17_2024-04-29.pdf

This document is a comprehensive set of electrical one-line diagrams for a normal power system, essential electrical system, and medium voltage system at an energy center facility located in Aurora, Colorado.

The diagrams illustrate the complete electrical infrastructure including primary and backup power generation, distribution transformers, feeder schedules, and circuit configurations serving multiple building systems. The normal power system diagram shows the main service entrance with primary utility feeds, generator backup capability, and distribution to various facility loads through step-down transformers. The essential electrical system diagram depicts the critical loads configuration with automatic transfer switches for seamless failover between normal and backup power sources. The medium voltage one-line diagram details high-voltage distribution architecture with interconnected transformer banks and load centers. Each diagram includes detailed transformer schedules and feeder schedules identifying voltage ratings, amperage capacity, conductor sizes, and specific load designations. The design incorporates redundancy and sectionalizing capabilities to maintain power to essential building functions during utility outages. Consultants listed include multiple engineering firms, with architecture/engineering coordination noted as completed as of the date shown on the drawings. The diagrams serve as the baseline electrical design document for construction and operational purposes at this federal facility, with comprehensive technical specifications embedded within transformer and feeder schedule tables accompanying the schematic representations.
