Studies on the influence of corona on overvoltage surges

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 ence S.A. All rights reserved.
