| Abstract |
Due to the steep-edged voltage impulses from the new generation of power electronics, the lifespan ofstator insulation systems is significantly shortened. In this paper, a three-phase high-frequency (HF)model based on multi-conductor transmission line theories (MTLs) is developed to predict the electricalfield distributions of each conductor in the line-end coils. In addition, the results of possible best andworst conductor spatial distributions in the stator slot from the one-phase HF model on the basis ofgenetic algorithms are also further investigated by the three-phase HF model. Finally, the theoreticalresults are validated through partial discharge measurements. |
