Breakdown withstand of insulating liquid with paper insulated electrodes : A numerical approach

摘要

Paper investigates the use of newly defined numerical method based on weak-link theory in the context of insulating liquid AC breakdown withstand improvement using impregnated paper coating of the electrodes. It is shown how liquid-impregnated paper differently affects breakdown withstand depending on field non-uniformity. Based on these findings, guidelines for breakdown withstand improvement are presented.
