Abstract: The efficiency of a transformer core is affected by the design of the joints used at the junctions. Air gaps cause some variations on the flux distribution at the joints of the transformer laminations depending on the geometry. For this purpose, two samples were formed by electrical steels, so different geometries were prepared. A varied flux distribution was determined from an array of search coils for each sample. 2D model of the samples formed by three layers of overlapped laminations was used to compute the magnetic flux distributions. It was observed that flux density in sample-1 starts to approach saturation at low flux density level compared to sample-2. In addition that the geometry of sample-2 design causes the flux distribution to be more uniform than that of sample-1. At high frequencies, the sample-2 is more efficient than the sample-1 because of increasing flux density.
