Research programs are investigating and testing the options of ultra-high voltage alternating current (UHVac) and utra-high voltage direct current (HVDC). The testing covers corona, field effects, insulator contamination, and air gap strength. Corona testing indicates that an eight-conductor bundle with 1.6-inch-diameter subconductors performs acceptably for 1200 kilovolts. Field tests are set up to determine and reduce the effects of exposure to the electric field. Flashover tests are made on various types of long insulator strings to determine which factors influence the relation between string length and flashover voltage, while various types of large conductor-to-tower and conductor-to-ground air gaps are used to test the ability to withstand switching surges. HVDC, with economic and environmental advantages, is usually preferred for long distance transmission of large blocks of electric power.
