“…This study will use the Eq. ( 2) model as a reference in the calculation of the (I-V) characteristic model, with constant C being a geometric function of the capacitance as proposed by [14,15]. The capacitance function in the corona discharge is different from the capacitance function in the case of ordinary electricity [23,24].…”

“…The geometric part has also been discussed [8] to compare the corona current function and the voltage's square function. In the research [14,15], the geometric part comes from the modified capacitance function by adding a multiplier factor k to the sharp surface of the active electrode. The value of factor k came from the suitability factor between the analytical formulation and the experimental results (curve fitting value).…”

This study does not use a physical approach from Maxwell's equations but a geometric approach from the active electrode tip of the capacitor, which gives rise to the shape sharpness factor of k [14,15]. Wardaya et al [14] used an active electrode tip approach in the form of a sharp line, Wardaya et al [15] using a sharp semicircular active electrode shape with pointed left and right sides.…”

The (I-V) characteristic pattern of the corona discharge case is very different from the pattern of ordinary electric circuits, so it is interesting to investigate. Several previous studies involved the concept of Maxwell's equations on several physical case models such as coaxial cylinder, electrohydrodynamic, and the electric wind. In this study, we use a capacitance calculation model for positive dc corona discharge in air, especially in calculating the (I-V) current-voltage characteristics of an electrode configuration model, often referred to as capacitively coupled plasma (CCP). The configuration model comprises active and passive electrodes, with the active electrode in the form of a pentagonal with the sharp end (in the middle) facing downwards in an upright position. The passive electrode under the active electrode has a large rectangular shape in a lying place. This configuration model is named The Chisel Eye and Midpoint-Plane (CEM-P). The analytical calculation of the (I-V) characteristics uses the geometric properties of the active electrode, which will produce a large corona current flow at the pointed electrode. These properties in analytical calculation manifest with the emergence of the corona flow multiplication factor at the sharp active electrode’s integration boundary condition called the shape sharpness factor k. The Python GUI Programming simulation program makes graphic simulations, Standard Deviation (SD), t-tests, and calculating the factor k (fitting curve value) between numerical calculations and research data. The values of the SD, the t-tests, and the Percentage of tangent points meet the requirements for a high level of accuracy for the four CEM-P configuration models of the (I-V) characteristics simulation graph with the graph has a relatively large percentage of tangent points values (82.35% – 94.44%).
