For magnetic energy loss measurements on electric steel sheets, the Epstein tester (ET) is applied for 100 years. However, it suffers from unsolved problems, such as inhomogeneity of flux in the corners and even more of impact of sample cutting. As a

Magnetic energy losses of silicon iron (SiFe) sheets are determined by the standardized methods of single sheet tester (SST) or Epstein tester (ET). The ET is much more compact and can be applied in a large range of frequency. However, it suffers fro

In the recent years, the reducing of audible noise of laminated machine cores has become great importance, due to high relevance given to environmental awareness. The strain caused by magnetostriction and magnetostatic forces is recognized as one of

Traditionally, flux distributions in transformer cores are modeled as a 2-D problem. However, experimental studies indicate that 3-D models are needed. The main reason is that limbs of circular cross section are combined with roughly semi-circular yo

In transformer cores, path length differences, material anisotropy, magnetic saturation, and impact of the overlaps (OLs) cause regional induction inhomogeneities and distortions. The global building factor of the core shows significant increases. Th

This paper puts a novel methodology of "multi-directionally non-linear magnetic equivalent-circuit calculation" (MACC) for discussion. It models transformer cores of Goss texture through local elements that are represented by non-linear magnetic resi

For the development of new strategies for reduction of energy losses and audible noise of transformer cores, the assessment of the induction distribution is essential. The results confirm that the core represents a strongly inhomogeneous 3-dimensiona

This paper concerns, the problem to assess 3-D distributions of magnetic induction in soft magnetic systems like machine cores of transformers or generators. Within bulk material, estimations of distributions are restricted to numerical methods like

The literature reports various transformer model core studies on local values of the building factor (BF), which consider the core as a 2-D single-package object. For the first time, we report 3-D BF analyses of a three-phase core that exhibits three
