Abstract
The paper presents experimental investigations to study the effect of enviromental moisture and pollution on the visual corona voltage for parallel wires of different diameters and at various distances from each other. It has been found experimentally that enviromental moisture and wet pollution have a reduction effect on visual corona voltage. The empirical equation given by Peek for such voltage is modified with the aid of the obtained experimental results. The proposed modification takes into consideration the effect of enviromental moisture and pollution on the voltage of visual corona formed between parallel conductors. The results using this modification match thobe obtained experimentally for both solid and stranded conductors. The maximum percentage error attained on applying the proposed modification does not exceed ± 8% of the experimental values. Discussion of the results and corona nodes in atmospheric air are also included and explained according to the modern concepts of this phenomenon.
