I fear I'm missing a major part of understanding. Electrical Transfomers and Rotating Machines 4th, Chapter 8 Review question 10. The secondary has a line voltage of 480v going into a delta with 6ohm loads. I took the line voltage from the wye transformer and treated it as a phase voltage to the load since the load is in delta. That gives me 480v/6ohms = 80amps but since the load is in delta I multiplied the 80a by 1.732 to account for the additional current caused by the other two loads in delta giving me my answer of 138.6amps for the line current. Then since the transformer is in wye I treated the line current equal to the phase current giving me 138.6amps in the secondary winding.
Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.

Solved in 2 steps
The book says I should have found 46amps. Is this a misprint?
