480/240 Volts for Farmstead Electrical Systems

A number of practices have been used to improve voltage regulation of electrical systems and equipment performance on farms. An increase of secondary voltages from 240/120 to 480/240 V would provide an even greater improvement and substantially reduce costs of secondary services for large installations. Farmsteads with large loads, long feeders and branch circuits, and those with scattered utilization points will receive the greatest benefits from higher farmstead voltages. Conductors, service equipment, and many utilization devices are commercially available for 480/240 V. Several types of three-phase and single-phase systems may be used with the higher voltage secondary system. Dry-type transformers would allow operation of present utilization devices requiring 240/120 V.
