Flux density and power loss distribution in 100kVA Distribution Transformer core assembled with different cutting angle of T-joint

The power losses occurring under magnetising condition have received a great deal of attention for a long time. The transformer designs with Butt Lap joint cause the highest power loss at the T-joint. These due to the flux need to rotate 90º into the hard direction and transfer up and down to the ad...
