Techno-economic analysis of the thermal energy saving ...· The transformer used in the Moyle interconnection station is of the OFAF type, which cooling system schematic is shown in Fig. 11. The heat produced by the transformer is dissipated by the oil circulating between the transformer and radiator. In the radiator, the heat content of the oil is reduced with the aid of a fan which blows air from below.[email protected]
