Abstract

The major considerations involving the selection of the voltage level for distribution facilities, principally 25 kV and 35 kV systems are discussed, and Virginia Power´s experience with 34.5 kV is highlighted. It is shown that significant savings can be achieved with higher voltage distribution in the cost of plant required per MWh delivered with no sacrifice in reliability. Higher voltage distribution also provides a reduction in energy losses, substation and line construction, thermal problems, operating and maintenance costs, and manpower requirements. Guidelines are suggested for the establishment and the conversion of facilities to a higher distribution voltage for a given area
