Abstract :
A stacked three-phase, three-limbed transformer core model was assembled from POWERCORE strip sheet, and the localized rotational flux distributions and distribution factors were measured using arrays of cross-shaped search coils. In studies of the two-dimensional magnetic properties of amorphous magnetic materials, we previously reported that a remarkable anisotropy was observed under high magnetic flux density conditions. The influence of the anisotropy on the flux distributions at the T-joint in three-phase transformer cores became a topic of interest. In this paper, the rotational flux distributions in the amorphous transformer core are investigated using a three-phase three-limbed core model assembled from POWER-CORE strip sheet.
