Fundamentals of design of electric energy delivery systems

Fundamental economic factors involved in the design of systems for delivering electric energy to typical urban load areas are discussed and analyzed in this paper. The fundamental principles presented already have been applied in a practical way in the design of a radial system recently built in Buffalo, N. Y. Engineering studies upon which the selection of that system was based led to the conclusion that for areas of load densities too low to justify a low voltage network, a properly designed radial system is likely to be the most economical and satisfactory system.
