Abstract
Before impregnation with fluid a capacitor roll, or a transformer core and coil, is filled with a monomeric gas that is thereafter polymerized, in situ, in a plasma discharge. Formation of solid polymer occurs at the regions of most intense electric field, thereby raising both corona-start and operating voltage for these devices.
