Analysis and calculation on temperature rise test ofanUHVconverter transformer

By analysis of the principle of temperature rise test of a converter transformer , differencesof the temperature-rise tests between a converter transformer and an ordinary transformer werecompared, and the calculation mode of total load loss from temperature rise of a converter transformerwas expounded. Through an example of temperature rise test of an UHV converter transformer, thecalculation of the total load loss of the converter transformer and the determination of the thermal time :constant were introduced, and relevant suggestions were presented.
