ABSTRACT:
An impregnated electric wound capacitor has a dielectric consisting of synthetic foils which are wound with paper tapes. The synthetic foils are impregnated with mineral oil and swell such that a residual impregnation gap remains between dielectric and the paper tapes. The existance of such a residual impregnation gap assures that re-impregnation will occur after the capacitor is subjected to temperature changes during operation or after a gas pocket develops due to a partial blow-out.
