Abstract

On the basis of the percolation model for electrical breakdown, a theoretical approach was proposed to investigate the correlation between morphology and breakdown strength. By introducing the sites of micro-voids in the percolation model, the effect of free volume was reflected and the morphology change was expressed by the aggregation pattern and the orientation of voids. Monte-Carlo simulation confirmed that the breakdown strength decreases with the increase of free volume, changes with the void shape and size distribution, and can be improved by orientation.
