Research on transient characteristics of segmented-layer winding under lightning impulse voltage

Abstract In this paper, the transient state of the segmented-layer winding was carefully analyzed and rigorously experimentally verified under lightning impulse voltage for the first time. Based on the self-designed segmented-layer winding, the equivalent circuit was established, and the adopted calculation method for the distribution parameter of the equivalent circuit was also universal. Furthermore, the analysis method of the transient state for segmented-layer winding was demonstrated to be reasonable and effective under lightning impulse voltage. The research results of this paper can provide theoretical and technical support for the electric power industry and its related electrical equipment manufacturers and have very important economic value.
