Design of booster shed parameters for post insulators under heavy icing conditions using geometric modelling and the Taguchi method

Flashover performance of ice-covered post insulators with booster sheds using experiments and partial arc modeling

“…4) In order to understand better the effect of each IFLDs (IFLD 1-t and IFLD 2 ), by using the geometric model of the BS configurations [24], it is recommended to perform some BS experiments with strong wind speed (much higher than the usual 3.3 m/s).…”

“…In other words, the role for which IFLD is more important in the increase of flashover voltage? By using the geometric model of BS configuration [24], we can conclude that strong winds lead to a significant decrease in IFLD 1-t but have no effect on IFLD 2 . So, to advance this work and to better analyze the role of the IFLDs, it is suggested to perform some BS experiments with wind velocities much higher than the one used (i.e.…”

“…Also, under icing conditions, an improved hypothesis or theory regarding the effects of BSs was proposed by the authors [22]. This hypothesis was based on computer-aided analysis and experimental test validations at CIGELE laboratories [23][24][25]. In brief, in the case of BSs it was found that their principal influence is the formation of air gaps and their minor influence is increasing dry arcing distance.…”

Influence of electric field on the ice‐coating process of insulators with a different dielectric surface

“…The glaze is thought as the most serious icing problem in a power network, for the hard icicles of which can distort the electric field of insulator surface [10][11][12][13]. Thus, the partial discharge or even arc may happen on the insulator surface, which threatens the stability of the power transmission network.…”
