Investigation of Electric Field Patterns for Different Electrode Configurations with the Presence of Dielectric Barrier

Numerous electrode designs, such as a sphere, point, rod, and plane, are used to study the breakdown properties of gases where the field might be uniform or nonuniform. In this work, the electric field behaviour with the presence and absence of dielectric barrier Polyvinyl Chloride (PVC) was examined using the finite element method (FEM) to quantitatively assess how a dielectric obstruction affects the patterns of electric field and voltage distributions in electrode configurations that are oriented vertically. In this study, the spatial distribution of the electric field is examined over a range of barrier- and barrier-free electrode designs. The field analysis has been analysed using the COMSOL Multiphysics simulation tool, and experimental verification of each electrode design with and without a barrier was also conducted. Four distinct types of electrode configurations were selected. The field computation results show the manner in which the conditions of the environment, the dielectric barrier, and the types of electrodes affect the maximum electric field fluctuation. As a result, when the barriers were placed between the electrodes, the electric field intensity was at its peak.
