The single-phase, 50-kVA, 2400:240-V, 60-Hz, two-winding distribution transformer is connected as a step-up autotransformer, as shown in Figure. Assume that the 240-V winding is provided with sufficient insulation to withstand a voltage of 2640 V to ground.
(a) Find VH , VX, IH , IC, and IX corresponding to rated (full-load) conditions.
(b) Determine the kVA rating as an autotransformer, and find how much of that is the conducted kVA.
(c) Based on the data given for the two-winding transformer, compute the efficiency of the autotransformer corresponding to full load, 0.8 power factor lagging, and compare it with the efficiency calculated for the two-winding transforme.

Q. Why positive feedback is used in oscillator? The main application of positive feedback is in oscillators. An oscillator generates AC output signal without any input AC signa
A signal comprises a bandwidth of 1kHz centred around 1kHz. A sine wave along with a frequency of 1250Hz is added to the signal. The bandwidth of the new signal is: 2250Hz
Q. How do you modify the direction of rotation of a D.C. motor? Ans: The direction of rotation of DC motor will be changed either by changing the field winding connections o
A feedback control system with the configuration of Figure has the following parameters: K p = 0.5 V/rad, K a = 100 V/V, K m = 2.7 × 10 -4 N·m/V, J = 1.5 × 10 -5 kg·m 2 , and
