Quantification of Corona Discharge Intensity Applied to Sphere-Plane Configurations

Year: 2025

Type: article

Abstract: This paper proposes several experimental methods for the quantification of the intensity of corona discharges under alternating current (AC) and positive and negative direct current (+DC and –DC) power supplies. These methods are based on the measurement of voltage and corona current, the energy associated with the corona pulses using high-frequency probes and a high-frequency oscilloscope, the apparent charge using a partial discharge (PD) detector coupled to a coupling capacitor, and the intensity of images taken with a digital camera. The experimental results presented are based on a sphere-plane electrode. However, many other electrode geometries can be studied based on the developments made in this work. In addition, an analysis of the advantages and disadvantages of the different methods is presented.
