Abstract
Disclosed is a dielectric fluid which comprises about 5 to about 40 molar percent of a first arene compound having up to seven substituent alkenyl carbon atoms and about 60 to about 95 molar percent of a diluent. The diluent can be mineral oil, a second arene compound having up to seven substituent alkyl carbon atoms which are hydrocarbons, hydrocarbon ethers, or a mixture thereof, or a mixture of a mineral oil and a second arene compound. Also preferably included in the dielectric fluid is about 0.5 to about 5% of a free-radical polymerization inhibitor. A capacitor and a transformer containing the dielectric fluid are also disclosed.
