Abstract
A dielectric fluid comprises an isoparaffinic base oil and hydrogen donor compound. The base oil may be a hydroisomerized isoparaffinic oil, and the hydrogen donor may be a substituted, or partially saturated aromatic compound. The resulting dielectric fluid exhibits negative hydrogen gassing properties along with good oxidative stability and low temperature performance.
