Professor Yarbrough has designed his Electrical Engineering Reference Manual to be a single reference for the broad field of electrical engineering, giving electrical engineering PE applicants the best exam review possible. Using tables, figures, and problem-solving techniques, this manual thoroughly covers every exam subject, including operational amplifier circuits and systems of units. It contains more than 400 practice problems, and fully worked-out solutions are found in the separate Solutions Manual.The load bus is at 90% voltage, and the motor is running at 50% current with a power factor of 0.8 leading. ... Timed 1. A 250 kVA, three-phase distribution transformer with a 440 V secondary and a 4% reactance supplies an induction motor ... Determine the required transformer ratings if (a) a 10 kW resistive single- phase load is added to the a-b leg, and (b) if a 10 kW resistive load is added to the b-c leg.
