Structural Design Criteria for Energy Savings in Electrical Installations

The system architecture modeling pursues its goals on safety, on energy and costs saving, on operational performances, selecting and sizing the electrical system components, at the sources level, such as transformers and generators set, at the distribution level, such as cables, fuses, breakers and switches, all connected either in series or parallel between system nodes. A centered distribution configuration allows landing reduced voltage-drop and reduced losses, modeling the system with components of smaller size guarantees a higher value of current densities, reduced volume of conductors and other related goals of efficiencies. Natural criteria for selecting and sizing the system components and for modeling the distribution structure are highlighted to assist the system "architecture" design that rises generally as a comprehensive solution of a linear system of many elements, cooperating ones, contrasting other ones, guided by an intuitive process based on the designer\´s professional skills.
