Bus calculations

The process logically starts with the selection of materials based on performance requirements, budget, design standards, and fabrication/installation codes to be met. The design of multiple forced-cooled buses within a space-restricted envelope at a public regulated facility has its own challenges. The first iteration in sizing is critical for subsequent calculations like stress/seismic analysis, electromotive force (EMF) effect, cooling, life-cycle cost, etc. This article provides a baseline bus-sizing calculation that can also be used as a tool for procedural validation of calculations performed by software, if any. The criticality and impact of sizing calculations on subsequent efforts are enormous commercial sizing software could have a black-box approach without disclosing the underlying methods used and, in turn, not empowering sensitivity analysis. Public regulated facilities often demand alternative analytical calculation.
