A THEORETICAL STUDY ON BREAKDOWN VOLTAGES IN $SF_6$ AND $N_2$

$SF_6$와 $N_2$ 에서의 절연 파괴 전압에 대한 이론적 고찰

In this paper, the theoritical breakdown characteristics of $N_2$and $SF_{6}$ in uniform field are studied by streamer criterion and the effective ionisation coefficients. Evaluation of the breakdown voltage for $N_2$and $SF_{6}$ has been done over following ranges: $N_2$: 100.0 $\leq$pd$\leq$10000.0(Torr cm) $SF_{6}$: 100.0$\leq$pd$\leq$6000.0(Torr cm) Computed values are compared with those of experiment. The results show a good agreement between the computed and the experimental values.
