Calculation of Corona Losses Beyond the Critical Gradient in Alternating Voltage

After a brief description of the physical phenomena of ionization, charge movement, and ionic recombinations, a very schematic description of the corona cycle results in a loss law which, in particular, shows the influence of the conductor capacity. A more accurate calculation method is then described, the results of which agree very well with experience. This law enables the conductor losses to be determined beyond the critical voltage by the sole determination of its critical gradient.
