Abstract :
The effect of pressure on dc breakdown voltage of contaminated porcelain insulators and glass models was investigated in the range of 13 to 100 kPa. The study revealed that flashover voltage decreases nonlinearly with lowering of pressure. Arc characteristics under different pressure conditions were studied and the theoretical basis of low pressure flashover is discussed.
