“…These studies noted that the breakdown voltage is a function of the distance between the electrodes and their shape, the dimensions, the nature and position of the barrier and the applied voltage type [12], [26]. The investigations were conducted using three types of voltage: DC voltage [16], [18], [24]− [26], AC voltage [1], [15], [17], [26] and impulse [8]− [10], [19]. The maximum disruption voltage is often obtained when the barrier is placed close to the sharp electrode (up to 25% of the studied interval length) [1], [8], [11], [26].…”

The present paper deals with new modeling to reproduce the electric discharge in the rod-plane air gap system with rubber insulating barrier under AC and impulse voltage. This model considers the randomness character of discharge evolution which is governed by the electric field. The discharges shape obtained by this model are compared with ones given by experimental tests. The established model reproduces correctly the forms of discharges obtained by experimental tests under AC voltage. It is found that the behavior of the electrical discharge depends not only on the dimension (thickness and width) of the insulating barriers but on its positions in the air gap as well. It is to highlight that the mode of applied voltage is of key importance barrier. Experimental investigation shows that the developed arc can evolve on 1 to 4 channels. The generated discharges in AC voltage distinguish by the formation of a multiple-channel arc. Whereas, the discharge under lightning impulse voltage found to progress in a single channel whatever the barrier position and dimensions. The model confirms that electric field is the most important factor in the behavior of the rod-insulating barrier-plane system submitted to high voltage.

“…In the case of air insulation, there has been a lot of researches conducted to clarify the electrical breakdown path and voltage characteristics according to the solid dielectric barrier. However, few studies have been conducted on the puncture breakdowns of solid dielectric barriers [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

This study deals with the electrical breakdown characteristics of the sphere‐plane electrode system with the dielectric barrier of bulk moulding compound (BMC) material under the positive lightning impulse voltage. The sphere electrode has a spherical shape of 50 mm in diameter and suspended with a metal rod of 10 mm in diameter, while the plane electrode has a circular with a diameter of 350 mm. The dielectric barrier has a square plate shape of BMC material, and the dimension is changed from 80 × 80 to 240 × 240 mm2. Experimental results show that electrical breakdown paths could be identified into three categories, depending on the dielectric barrier position and the dimension. The larger and farther away from the sphere electrode the dimension of the dielectric barrier is, the occurrence probability of electrical breakdown through the penetration of dielectric barrier becomes. It was confirmed that the breakdown voltage considerably depends on the dimension of the dielectric barrier and the dielectric barrier position.
