Conditions for a self-sustained D. C. corona discharge

抄録

In this paper, a theoretical model allowing to plot the breakdown voltage VB as a function of the pressure×gap distance product (pd) is presented for a D. C. corona discharge. For a parabolic point, it is shown that Paschen-like curves are obtained, the result being dependent on the point tip radius. Finally, this model is compared to experimental results obtained in nitrogen and air.
