Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.

Question

a. Draw the transformer connection that can do this job.

b. In the connection you have drawn, the apparent power of the transformer (in rated operation state, the load power to be transferred) what happened.

c. Calculate the maximum primary and secondary winding currents for the connection situation you have drawn.
