Calculation of Corona Voltage-Current Characteristics in Air
Paper i proceeding, 2009

This paper focuses on numerical simulations of positive dc corona in air in coaxial cylindrical electrode arrangement. The study aimed at developing a computer model accounting for background physical processes in corona discharge and its verification by means of comparison of calculated corona characteristics with experimental data. Several parameters of corona, namely, inception voltages, voltage current characteristics and onset field strength values were used for evaluations of the model performance. The validated model was further utilized to investigate the effects of ion mobilities on corona current and variations of the ionization intensity on corona inception voltages.
