Abstract
THE most generally adopted systems of oil-preservation, for large high-voltage transformers have been: (1) the oil-conservator system, in which the oil level surface is at constant atmospheric pressure; and (2) the gas-pressure system, in which the upper part of the transformer tank is maintained under a positive gas pressure which is allowed to vary up to approximately 8 pounds per square inch, as the oil volume varies with temperature.
