| Title: | Calculation of eddy current field in the ascending flange for the bushings and tank wall of a large power transformer | Authors: | Ho, SL Li, Y Tang, RY Cheng, KWE Yang, S |
Issue Date: | Jun-2008 | Source: | IEEE transactions on magnetics, June 2008, v. 44, no. 6, p. 1522-1525 | Abstract: | The 3-D open boundary eddy current field induced by heavy current flowing in the coils and winding leads in large power transformers is calculated. The eddy current loss and local overheating problem in the tank wall and in the ascending flange of bushings are analyzed and reported in this paper. The effectiveness of a magnetic bypass plate near the coil ends for reducing the eddy current loss and local overheating in the clamp plates is discussed. | Keywords: | Eddy current field Loss Power transformer |
