About this file

Written by GovTribe AI ·

This document is an electrical power schematic drawing for the Halls (HX) Substation SCADA & Comm Racks, prepared by the Knoxville Utilities Board (KUB) for their Halls Substation Rebuild project. The technical drawing details the AC and DC power distribution configuration for various critical infrastructure components, including circuit breakers (CB1-CB6), power supplies, transducers, and communication equipment such as RTAC, Axion units, HMI, and GPS systems.

The schematic illustrates a complex power distribution layout with multiple power connections and redundancy, indicating a sophisticated electrical infrastructure design for the substation control systems. The drawing is labeled with job number D-18922 and appears to be part of a larger engineering documentation set for the substation rebuild, which aligns with KUB's bid #3855 for control panels with freight included under FOB Destination terms. The technical complexity suggests this is a critical upgrade to the utility's power infrastructure, likely aimed at improving monitoring, control, and reliability of the electrical distribution system.
