The invention deals with increasing the quality of insulating mineral oil in transformers, by providing an isolating layer of flowing nitrogen over the oil's surface to keep ambient air from combining or absorbing with or in the oil, also providing a kidney or alter to remove undesirable contaminants such as water, oxygen, free radicals and debris from the oil, and providing a means of sensing trace gases produced in the oil responsive to transformer conditions and mixed with nitrogen flow to diagnose transformer conditions of interest such as hot-spots, short circuits, insulation failure or similar indicators of failure or incipient failure or need for service, the trace gas analysis being capable of remote monitoring and interpretation. The invention has application in the field of transformers where it is useful to provide self-sufficient and environmentally equipment and methods to prolong service life and reliability between service or inspection of medium, high, and extra-high voltage power transformers.
