The gas insulated transformers have been developed and applied to substations widely, because of non-flammability and compactness. In this type of transformer, the coolant gas is forced to flow in the gap between coils to cool them. This cooling performance is influenced by the gas flow pattern in windings. Therefore, it is important to know flow distribution to develop coil structures for cooling. In this paper, the appropriate flow path configurations were determined on the basis of numerical analysis. These analytical results are verified in comparison with the measured data.
