Abstract (en)

[origin: WO2006097142A1] The invention relates to a method for controlling devices for cooling an oil-filled power transformer with one or more cooling stages during which only the respective type of cooling of the transformer and the type of coolant for each existing cooling stage have to be input and by comparing with all non-volatile stored technically possible and meaningful combination possibilities, the corresponding characteristic quantities are determined for calculating the oil temperature or winding temperature.
