Question:

a. Consider the Y-Y transformer connection of Problem 2.35, part (b). If the rated voltage is applied to the high-voltage terminals and the three low-voltage terminals are short-circuited, calculate the magnitude of the phase current in per unit and in amperes on (i) the high-voltage side and (ii) the low-voltage side.

b. Repeat this calculation for the Y-A connection of Problem 2.35, part (c).
