A fairly simple mathematical model to predetermine the charge-voltage chara
cteristics of a transmission line under the influence of a surge corona has
been presented in this paper. This model has been used to compute the atte
nuation and distortion of the surges as they propagate along the line. In a
ddition, the corona current waveforms have also been computed and presented
. The deformation suffered by very fast surges due to the corona has also b
een investigated and results presented in this paper. (C) 2000 Elsevier Sci
