Measurements and simulations of corona currents due to triangular voltages in large scale coaxial geometry
Paper in proceeding, 2012
Corona currents in air measured in a large scale coaxial geometry (d_outer = 1 m, d_inner = 0.26 mm), under both DC and AC voltages of a triangular shape with frequencies in the range (1 – 50) Hz are analyzed. A computational model describing dynamics of positive and negative ionic charges is employed to examine the results of the measurements. The performed simulations show a good overall agreement with the experimental data.
