Evaluation of Electromagnetic and Magnetic Shielding Configurations Related to Large Power Transformers

摘要

This paper details the electromagnetic behavior and the effects of magnetic and electromagnetic shields used in large power transformers based on engineering-oriented benchmark models, presents some newly calculated and measured results of both magnetic field and stray-field loss related to the models, and examines the engineering applicability of 3-D eddy current analysis methods and the practical loss modeling.
