Abstract :
Gases generated in power transformers with gas space above oil distribute between the gas space and oil. The relative concentrations vary with oil temperature. Adjustment ratios are computed for temperature variations. Comparison is made with transformers without gas space. Finally, the effect on gas ratios used in Ratio Codes is examined.
