Research on the Effect of Metal Electrode Coupling Voltage under Induced Electrostatic Discharge

Abstract

In this paper, the mechanism of electrostatic discharge induced by a strong electromagnetic field was studied through software simulation and test verification. By focusing on the effect mechanism of coupling voltage between metal electrodes to induce electrostatic discharge, we obtained the law of electrostatic discharge induced by the strong electromagnetic field. In the process of electrostatic discharge induced by the strong electromagnetic field, due to the antenna receiving effect of metal electrode structure, the strong electromagnetic field would form coupling induction voltage on the metal electrode. The voltage acts on both ends of the discharge electrode structure and generates an electric field in the gap between the electrode structure, which superimposes on the original field; furthermore, it has an impact on the electrostatic discharge process, resulting in the formation of induced discharge with low charging voltage structure.

Suppression of dielectric surface flashover induced by strong electromagnetic field at multiple spatial scales based on above/sub-surface discharge development mechanisms

“…Hu et al studied the influence of irradiation field strength, beam energy, and dielectric thickness on induced discharge characteristics of dielectrics under EMF irradiation, finding that induced discharge frequency increases, while the accumulated charge on the dielectric surface decreases as the irradiation field strength increases [18]. Zhang et al developed an experimental setup to study the discharge characteristics of needle-ball corona induced by strong EMF, initially obtaining the basic law of induced discharge [19]. However, it is worth mentioning that the breakdown voltage of the vacuum-dielectric interface is significantly lower than that of the dielectric bulk and pure vacuum under the same insulation distance, resulting in ESD events preferentially occurring over the vacuum-dielectric interface (i.e.…”

“…However, the research on electrostatic discharges induced by strong electromagnetic fields is still in its infancy, mainly focusing on the study of metal electrodes [17][18][19][20][21]. Hefei Cao et al obtained the variation in threshold voltage of needle-plate corona discharge in vacuum tube induced by electromagnetic pulse through the developed simulation experiment system of electromagnetic radiation field [17].…”
