| Abstract: | The influence of ions in the background on the impulse discharge characteristics in air is studied. In order to form a background with a certain ion density in the gap, an independent ion generator was used. The effect of positive and negative ions on the V50 of the rod-plane gap and that on the v-t curve were measured. The effect of positive and negative background ions on the leader velocity and pattern of discharge channel were also observed by the still camera and chopped wave. The mechanism of effects of background ions on discharge is tentatively explained. |
