Abstract :
Using an icicle/iced-plate system, the corona discharge at the icicle tip was investigated under positive DC voltage. The discharge pulses were recorded and analyzed. The relationship between the discharge magnitude and the time interval before the pulse was examined. The mechanisms underlying the corona discharges at icicle tips were investigated. The influence of space charge on the discharge and the effects of the applied voltage on the time interval between two pulses were also investigated. Finally, a model for calculating the drift and diffusion of the space charge cloud was presented.
