1- Consider the following three phase radial distribution feeder. The transformer is a 10 MVA, 115/13.8 kV three phase bank. a. Draw the per unit equivalent circuit b. Find voltage drops in per unit c. Find the voltage drop if the last load is changed to 25A at 0.72 lead d. What should be the tap of the transformer if voltage at C is 1 pu and voltage at the primary of the transformer is set at 1 pu.
