Cooling of Transformer is the process by which heat generated in the transformer is dissipated or treated to the safe value. The major factor for the generation of heat in the transformer is the various losses like Core losses (hysteresis, eddy current, iron) and Copper loss. Among all the various losses the major contributor of the heat generation is the Copper loss

The open-circuit test is used to determine the impedance in the excitation branch of a real transformer. This test only measures the combined iron losses consisting of the hysteresis loss and the eddy current loss. The purpose of a short-circuit test is to determine the series branch parameters of the equivalent circuit of a real transformer. This test measures only the full load copper loss.
