Intimate contact between transformer insulating oils and air results in the oxidation of the oils as well as contamination from moisture and other airborne contaminants, thus reducing the useful lifespan of the oil and increasing maintenance costs. Amethod and apparatus for the substantial elimination of such oxidation is comprised of an inert gas generator mounted in close proximity to a power transformer con-tainment tank and connected to the tank expansion chamber via at least oneconduit. A continuous flow of substantially moisture free inert gas, such as nitrogen, is generated at atmospheric pressure and introduced at one end of the expansion chamber via the conduit. The inert gas flows across the surface of a head of oil contained in the expansion chamber and is evacuated at the opposite end of the expansion chamber where it is dissipated in the surrounding atmoshere. The continuous flow of inert gas across the oil surface displaces and eliminates all air from intimate contact with the oil, thus substantially eliminating the cause of oil oxidation.
