About this file
This document is a technical wiring diagram for the Halls Substation SCADA (Supervisory Control and Data Acquisition) and Communications Racks, prepared by the Knoxville Utilities Board (KUB) for their Halls Substation Rebuild project. The diagram specifically details the terminal block wiring configuration for SCADA Rack #1, showing complex interconnections between various digital output (DO) slots, cabinets, and relay panels. The drawing is dated 3/26/25 and includes detailed routing information for connections to HX11-HX14 cabinets and multiple relay panels (P1SC1, P3SC1, P4SC1).
The technical schematic provides a comprehensive view of the electrical interconnection strategy, with precise mapping of terminal blocks (TR1-TR12) and their corresponding DNP (Distributed Network Protocol) digital output pairs across different slots (Slots C through H). The diagram includes notations for unbundled (UNBL) and bundled (TUNBL) connections, suggesting a methodical approach to electrical system design and integration. While no specific pricing is visible in this technical drawing, it represents a critical component of the Halls Substation control system infrastructure, illustrating the detailed engineering preparation required for the substation rebuild project.
