Comparative cost of distribution systems

THE PURPOSE OF THIS ARTICLE is to compare the effect, on the cost of new overhead, open-wire distribution systems, of using either 4.16 kv or 13.2 kv as alternative primary-feeder voltages for supplying load in the same area. The range of load densities considered is 125 to 16,000 kva per square mile. This load-density range is representative, therefore, of heavy-rural to heavy-urban loads.
