Variation of surface flashover voltage in SF6 with pressure
Surface flashover characteristics of solid spacers in a rod-plane configuration have been investigated in SF6, at pressures to 400 kPa, for switching impulse voltages to determine the effect of spacer, spacer materials and polarity of applied impulses ...
