The disclosure is directed to a thermally-stable dielectric fluid. The dielectric fluid includes (a) an oil, (b) a substituted, hindered phenolic antioxidant having at least two substituted cresol groups being covalently bonded to each other through a methylene bridge, and (c) a substituted, diphenyl amine antioxidant having at least two substituted phenyl groups being covalently bonded to each other through an amine bridge.

1. A dielectric fluid comprising: (a) an oil selected from the group consisting of algae oils, fatty acid esters, microbial oil, mineral oils, vegetable-based oils, and vegetable seed oils and;(b) a substituted, hindered phenolic antioxidant having at least two substituted cresol groups being covale
1. A dielectric fluid comprising: (a) an oil selected from the group consisting of algae oils, fatty acid esters, microbial oil, mineral oils, vegetable-based oils, and vegetable seed oils and;(b) a substituted, hindered phenolic antioxidant having at least two substituted cresol groups being covalently bonded to each other through a methylene bridge of the structure wherein R1-R10 is a hydrogen, a hydroxyl group, an alkyl group, an alkenyl group, an alkoxy group, or an aryl group and where at least one of R1-R5 and at least one of R6-R10 is an hydroxyl group, at least one of R1-R5 and at least one of R6-R10 is a methyl group, and at least one of R1-R5 and at least one of R6-R10 is an alkyl, alkenyl, or alkoxy group that may be straight-chained or branched or an aryl group and the alkyl, alkenyl, alkoxy, or aryl group may be substituted or unsubstituted; and(c) a substituted, diphenyl amine antioxidant having at least two substituted phenyl groups being covalently bonded to each other through an amine bridge of the structure wherein R1-R10 is, independently, a hydrogen, an alkyl group, an alkenyl group, an alkoxy group, an aryl group or a vinyl benzyl group, when R1-R10 is an alkyl group, an alkenyl group, or an alkoxy group that group may be straight-chained or branched and may be substituted or unsubstituted, and when R1-R10 is an aryl group that group may be substituted or unsubstituted. 2. The dielectric fluid of claim 1 further comprising at least one of a natural algae antioxidant, a metal deactivator or a pour point depressant. 3. The dielectric fluid of claim 1 wherein the oil is a vegetable seed oil selected from canola oil and high-oleic canola oil. 4. The dielectric fluid of claim 3 wherein the vegetable seed oil is a high-oleic canola oil. 5. A device comprising: (a) an electrical component and(b) the dielectric fluid of claim 1 in operative communication with the electrical component. 6. The device of claim 5 wherein the electrical component is selected from the group consisting of a transformer, a capacitor, a switching gear, a transmission component, a distribution component, a switch, a regulator, a circuit breaker, an autorecloser, and combinations thereof. 7. A process comprising the steps of: (a) placing the dielectric fluid of claim 1 in operative communication with an electrical component and(b) cooling the electrical component with the dielectric fluid. 8. A process comprising the steps of: (a) placing the dielectric fluid of claim 1 in operative communication with an electrical component and(b) insulating the electrical component with the dielectric fluid. 9. The process of claim 7 wherein the electrical component is selected from the group consisting of a transformer, a capacitor, a switching gear, a transmission component, a distribution component, a switch, a regulator, a circuit breaker, an autorecloser, and combinations thereof.
