Many studies, both experimental and numerical, were devoted to the electric current of corona discharge and some mathematical models were proposed to express that current. As this one depends on several parameters, it is difficult to find a theoretical or experimental formula which considers all the factors, so we opted for the methodology of experimental designs, also called Tagushis methodology, which represents a powerful tool generally employed when the process has many factors to study. The objective of this paper is to model the current using this experimental methodology. The factors considered were the geometrical factors (inter-electrodes interval, surface of the grounded plane electrode, curvature radius of the point electrode), the climatic factors (temperature and relative humidity) and the applied high voltage. Results of experiments made it possible to obtain mathematical models and to analyze the interactions between all factors.
