ABSTRACT:
An electric capacitor containing a winding of paper and/or synthetic dielectric foils and metallic coatings and having at least one winding which is disposed in a sealed gas-tight housing containing an excessive pressure safety system and filled with an impregnation fluid, such as mineral oil, up to a predetermined buffer volume. In accordance with the invention, the impregnation fluid is saturated with an electro-negative gas and the buffer volume in the housing likewise is filled with such gas in an amount which assures a pressure higher than the normal pressure but, lower than the response pressure for the safety system.
