Influence of flux collectors on stray losses in transformers

The paper proposes a reluctance network method for the three-dimensional analysis of a three-phase transformer. The analysis is aimed at assessing as to whether a laminated flux collector is effective in controlling the power losses of the transformer. The results are thoroughly superimposable to those which can be obtained by the traditional theory of the transformer. The main advantage is that the required number of nodes and elements for the analysis is definitely lower than with other techniques.
