Observation of Light Output from Corona Discharge on a High Voltage Wire Conductor Using the CT Technique

Abstract

Luminosity of wire corona has been observed by the technique of the computed tomography. The light output from wirecorona has been compared with the calculated result. Spatial distributions of space-charge and current density of each type ofcharges carrier in a corona field has been also determined by computing the ionization and attachment process under the Deutschassumption and compared with experimental results.
The calculated results along the symmetry axis of the electrodes show very good agreement with measurements.Unfortunately, there is a slight difference between the experimental results and those of the calculation under the Deutschassumption in the distribution of luminosity.
