Problem 3.5: From a 3-phase, 480 V generator switchboard, a feeder takes 3-phase power to two equipment at the other end via cable and trans- former with the combined series impedance Z = 0.04 + j 0.09 Q per phase. The voltage at receiving end point A rises and falls as a large 3-phase, 500 kVA load at point A varies over time. The small 1 kVA load, also connected at point A, remains online continuously, and must accommodate the voltage variations at point A with the 500 kVA load fully on or fully off. Determine the voltage range that the 1 kVA load will see, over which it must perform within its specifications.
