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.

F.
The line voltage on low winding is equal to the phase voltage on low voltage side which is 120 V because the windings on the low voltage side are connected in delta. The load resistors are connected in star, so the phase voltage is 1/√3 time of the line voltage on the low voltage side.
D: The phase load in the load side is equal to the voltage across each resistor because the load is connected is star. Thus, voltage per resistor is given by:
