D-18920 SH05 R00 - HX 125VDC SCH - PNL 2 - 1B87 BUS DIFF.pdf

This document is an engineering schematic drawing prepared by Knoxville Utilities Board (KUB) for the Halls (HX) Substation, specifically detailing a 125VDC schematic for Panel 2 - 1B87 Bus Differential. The drawing is part of the Halls Station Rebuild project, identified with job number J0008436 and engineering document number D-18920. The schematic appears to be at an "IFC" (Issued for Construction) stage, dated 3/26/25, and drawn by an individual with the initials TLK on 3/25.

The document provides a technical grid-based schematic diagram that likely represents the electrical control and differential protection systems for the substation control panel. While specific pricing details are not visible in this technical drawing, it is associated with KUB's bid #3855 for Halls Substation Control Panels, which will be procured with freight included (FOB Destination) in Tennessee. The drawing represents a critical component of infrastructure upgrade work for the utility's electrical distribution system, focusing on precise electrical control and protection mechanisms for the substation.
