Abstract
A method of processing an electrical apparatus, such as a capacitor, containing a polymeric dielectric material. The interior of the capacitor casing, which is at room temperature, is initially connected to a vacuum source to evacuate the interior of the casing and when a vacuum sensing unit indicates that the required vacuum has been obtained, a degassed dielectric liquid is supplied to the interior of the casing. A positive pressure is applied to the liquid in the casing to fully impregnate the polymeric layer. When the desired capacitance is obtained, the impregnation is complete and the unit is sealed.
