<p>A dielectric liquid composition consists of a predetermined mixture of an aromatic ester and certain chlorinated compounds. This mixture is used to impregnate an electrical capacitor, and provides an improved corona extinction voltage characteristic, an increase in the dielectric constant and decreased flammability. One working example utilizes a mixture of a liquid phthalate ester such as dioctyl phthalate, pr 2-ethyl-hexyl phthalate (DOP), and trichlorobenzene (TCB) as the impregnant for an electrical capacitor.</p> |
