【 摘 要 】

This paper describes results of an investigation of the variation of power loss, building factor, flux leakage and flux distribution in 3-phase model transformer cores assembled from various type of T-joint geometry. The loss of the core with T-joint 60o was 10%, 12% and 15% better than the core with T-joint 45^o, T-joint 23^o and T-joint 90^o respectively and 1.7 T, 50 Hz. The flux lines showed that flux penetration into the central limb was an important factor in causing the differences in performance.
