B) You have a choice between a cable where the transformer box is at the very end (right where you plug it in) and another cable where the transformer box is in the middle of the cable. Otherwise, the cables are the same (same size wire, same total length). Give a detailed and well-reasoned/supported discussion concerning which cable will waste less energy. (Essential hint: energy is wasted because the wire material in the cable has some resistivity. Also don't forget that transformers might affect the current.)

PowerWorid Simulator case Problem 3_60 duplicates Example 3.13 except that a resistance term of 0.06 per unit has been added to the transformer and 0.05 per unit to the transmission line. Since the system is no longer lossless, a field showing the real power losses has also been added to the oneline. With the LTC tap fixed at 1.05, plot the real power losses as the phase shift angle is varied from 10 to +10 degrees. What value of phase shift minimizes the system losses?

A single-phase 50-kVA,2400/240-volt,60-Hz distribution transformer is used as a step-down transformer at the load end of a 2400-volt feeder whose series impedance is (1.0+j2.0) ohm.
