“…In addition, it has been shown that, for switching surge calculations where frequencies are higher than supply frequencies, a simplification of the model to a single shell is sufficiently accurate to allow for this effect in switching surge calculations. The method previously used to represent corona by means of multiple charge shells to describe the effects of corona on AC steady-state power lines [14] has been shown to be applicable also to corona arising during surge phenomena on overhead lines. Unfortunately, owing to the somewhat complex shell emission and recombination, this model suffered from instabilities.…”

“…Owing to the nonlinear nature of the equations describing the distribution and the movement of the space charge, a general analytical solution to these equations is impossible; hence numerical interactive methods must be employed. In this respect, the method proposed by Clade et al [14], which was used to calculate AC corona loss, is particularly suitable.…”

“…Clade calculated the corona loss of a single conductor in a corona cage based on the assumptions of Kaptzov and Deutch, whilst ignoring the influences of space charges on the electric field direction. [13][14][15] By abandoning the Deutsch assumption, Abdel-Salam investigated single, triple, and multi-phase transmission-line corona loss, but did not consider the inhomogeneity of the electric field on the conductor surface and postulated that charges on the conductor surface were emitted uniformly. 16,17 By considering the heterogeneity of charge emissions on the conductors' surface, Li determined the ion flow of the multi-phase and bundle conductors.…”
