Measurements and simulations of corona currents due to triangular voltages in large scale coaxial geometry

Measurements and simulations of corona currents due to triangular voltages in large scale coaxial geometry

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...

Beschreibung
Zusammenfassung: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.
