Abstract :
The variations, with humidity, of the positive DC corona-current voltage characteristics and of sparkover stresses have been studied in rod-plane gaps of spacings in the range 103 in the largest gaps. In shorter gaps, the rod profile plays a larger role, and the transition from glow-controlled to streamer-controlled breakdown is demonstrated in the 20 cm gap.
