Abstract
The flux distribution in a right-angled corner of transformer laminations of hot-rolled and grain-oriented silicon-iron sheet materials has been investigated. The distribution of the harmonic components of flux in the corner region has been determined. From the results obtained it is estimated that in the grain-oriented material the core stray loss, in the particular magnetic circuit employed, amounts to about 24% of the Epstein loss, 21% being due to the flux flowing in unfavourable directions round the corner and 3% due to extra harmonic eddy-current losses.
