| Abstract: | The harmonic current components of an exciting transformer used to excitation in the large synchronous generator is analysed, and a method to calculate the eddy current loss in the winding is deduced in the paper, such case as the eddy current demagnetization being considered and the radial dimension of the conductor in the different layers being different could be dealt with. The truncation error in calculating the harmonic loss is analysed and a method is offered to determine how many times harmonics must be calculated at least. |
