In the given circuit, low voltage lines are seen coming out of a distribution transformer
whose Low Voltage side is star connected. R (QR = 0) phase for M1 line, S (pS = 120)
phase for M2 line andT (oT = -120) phase is used for M3 line. The impedances of the
loads at the end of the lines are (100 + j25) N and the impedances of the lines (1 + j) N.
