Evaluation of Corona Charge Positive and Negative Impulses on Polymeric Surfaces and Simulation of Impact Rate

Corona electric discharge phenomenon occurs when the electric field intensity exceeds the corona threshold. In the analysis of this paper, three types of hypotheses of partial charge (electrons, positive ions, negative ions) generated in the air due to corona electrical discharge are considered. The physical process is produced along with the changes and dynamics of the electric charge applied to the field by the charge movement which has velocity due to electric fields and motion due to slope (diffusion) and we will also see losses in electric charge. In this paper, electric load evaluation on a polymer surface by a positive impact corona in the air was performed. Output (circuit current) and input (electric fields and electric charge space density) are considered in computer simulation analysis. Different models have been used to identify the corona, depending on the intensity and extent of the voltage surges. The dynamics and distribution of electric charges and electric fields are analyzed and compared by two models of corona charging (glow and burst impulse).
