Abstract
Single-phase and three-phase transformer cores have been assembled from POWERCORE® strip. Laminated cores with mitered and butt-lap corners and T-joints were built. The cores were magnetized over a range of peak flux densities from 0.6 T to 1.4 T, 50 Hz. The localized flux density, localized losses, and total loss of various assemblies were measured. The building factor (BF) was measured in each case. Mitered joints produced lower BFs than butt-lap joints because of better flux uniformity although in both types the variation of localized loss was not so great as in silicon-iron cores. Mechanical stress or air gaps at the corner joints caused the BF to increase in all cases. One mitered core produced an exceptionally low BF thought to be due to optimization of flux transfer at the corner joints.
