| Abstract: | A model is developed for the gap electric field distortion of space charges. Discharge characteristics are described for point plane gaps in SF 6. Based on theoretical analysis and mathematical deduction, a relation is developed for the impulse rising rate and the delay time of streamer to leader transition. Results are given for impulses with different front durations, and the proposed model is verified experimentally. |
