Modeling of Trichel Pulses in the Negative Corona on a Line-to-Plane Geometry

In this paper, a 2-D time domain method is proposed to simulate Trichel pulses in the negative corona discharge on a line-to-plane geometry. Three ionic species in the ionization layer, including electrons, positive ions, and negative ions, are taken into consideration. The FEM is used to solve the Poisson´s equation, while the finite volume method is used to solve the charge transport equations. Trichel pulses on a line-to-plane geometry are analyzed and compared with the measured results of a designed experiment in the laboratory. Good agreement is obtained between the calculated results and the measured ones, verifying the validity of the proposed scheme.
