Surface flashover is a devastating electronic avalanche along the gas–solid interface when high electric field applied, which potential issue that threatens safe operations of advanced power electronic, electrical, and spacecraft applications. However, underlying physical mechanisms for surface development are still under investigation owing to complex charge transport processes through gas pha...
<span lang="EN-US">The number of lightning stroke on the tower 150 kV Koto Panjang-Payakumbuh transmission line located rocky area has been observed. The high value footing resistance indicates occurrence back-flashover in at intensity 74%. is dominantly triggered by value. Also, rate an effect considering electrode installations. A design proposed for grounding system footings order to r...
This paper addresses different issues regarding the lightning back-flashover performance of HVDC lines, especially double-circuit configurations. In such configurations, two poles may present very similar flashover risks due to a strike, leading double flashover. Therefore, it is particular interest investigate solutions protect at least one circuit from flashovers and avoid temporary loss tran...

Abstract—The flashover voltage of insulator is relative to the distribution of the electric field. The distribution of the electric field on the insulator is contributed to the shape of insulator. For this, we must optimize the shape of insulator. In this paper, we use FEM, GA and HGAPSO for optimizing the shape of insulator. The tangential electric field and the area of insulator are optimiz...
