Phase-Phase Switching, Suite Flashovers: Weather Correction Factors

Weather correction factors for spacings of 3 to 12 feet have been obtained from phase-phase switching surge flashover tests. New statistical methods of analysis of flashover data were used to show that correction factors published for phase-ground flashovers are inadequate for phase-phase. Correction factors for phase-phase flashovers calculated from relative air density, humidity, and relative humidity are given.
