Field grading in capacitor margins
Abstract
Some of the results of modeling electric fields in the margin of a bogey plastic film liquid impregnant capacitor are presented where effects of foil edge shape, different impregnants, and grading wires are examined. It is concluded that placement tolerance and connection problems make grading wires impractical and that folded foil edges are still the best solution to field grading.
