In this paper, a substation ventilation design is studied to determine the optimal design parameters to be installed within the room. Several models were investigated to mitigate the thermal issues in the substation by CFD analysis. The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L). Apply three-phase, four-wire, 208Y/120V systems for lighting and power demand loads less than 150 kVA. (3) Power distribution from tertiary switch boxes to electrical equipment must follow the "one machine, one switch" principle, with no branching allowed.
