Results are presented of the work performed at EPRI's Project UHV from January 1974 to December 1976. During this period, a three-phase ac test line with line voltages up to 1500 kV was constructed and operated. The feasibility of UHV transmission has been demonstrated and the most important problems impacting on cost and performance have been identified. Design data on the corona performance of conductor and line configurations and on the dielectric strength of the external insulation of UHV transmission systems have been provided. The results obtained confirm and extend the data contained in the Transmission Line Reference Book--345 kV and Above, published by EPRI in 1975.
