Abstract
A dielectric fluid and coolant for electrical apparatuses such as transformers. In one embodiment, the fluid contains more than 25% biobased base oil, such as a biobased hydrocarbon oil, which has a molecular weight greater than 300 g/mol and less than 595 g/mol. The biobased base oil may optionally be blended with other oils, such as mineral oils and vegetable oils.
