Question 11

In a constant V/f control of induction motor, the ratio V/f is maintained constant from 0 to base

frequency, where V is the voltage applied to the motor at fundamental frequency f. Which of the

following statements relating to low frequency operation of the motor is TRUE, A three-phase,

4-pole, self excited induction generator is feeding power to a load at a frequency f1 . If the load is

partially removed, the frequency becomes f2 . If the speed of the generator is maintained at 1500

rpm in both the cases, then?

Question 12

A three phase synchronous generator is to be connected to the infinite bus. The lamps are

connect ed as shown i n t he fi gur e for t he synchronization. The phase sequence of bus voltage

is R- Y- B and that of incoming generator voltage is R' - Y' - B'. A 3 phase, 50 Hz, six pole

induction motor has a rotor resistance of 0.1 and reactance of 0.92 . Neglect the voltage drop

in stator and assume that the rotor resistance is constant. Given that the full load slip is 3%, the

ratio of maximum torque to full load torque is?

Question 13

For a specified input voltage and frequency, if the equivalent radius of the core of a transformer

is reduced by half, the factor by which the number of turns in the primary should change to

maintain the same no load current is, A three-winding transformer is connected to an AC voltage

source as shown in the figure. The number of turns are as follows : N 1= 100, N 2= 50. If the

magnetizing current is neglected, and the currents in two windings areI 2= 2 30 A andI3= 2

150 A, then what is the value of the currentI 1in Ampere?

Question 14

A 3-phase transformer rated for 33 kV/11 kV is connected in delta/star as shown in figure. The

current transformers (CTs) on low and high voltage sides have a ratio of 500 / 5. Find the

currents i 1and i 2, if the fault current is 300A as shown in figure. A balanced (positive sequence)

three-phase AC voltage source is connected to a balanced, start connected through a star-delta

transformer as shown in the figure. The line-to-line voltage rating is 230 V on the star side, and

115 V on the delta side. If the magnetizing current is neglected andIs= 100 0 A, then what is

the value ofIpin Ampere?

Question 15

A 4-pole, separately excited, wave wound DC machine with negligible armature resistance is

rated for 230 V and 5 kW at a speed of 1200 rpm. If the same armature coils are reconnected to

forms a lap winding, what is the rated voltage (in volt s) and power (in kW) respectively at 1200

rpm of the reconnected machine if the field circuit is left unchanged , The synchronous generator

shown in the figure is supplying active power to an infinite bus via two short, lossless

transmission lines, and is initially in steady state. The mechanical power input to the generator

and the voltage magnitude E are constant. If one line is tripped at time t 1by opening the circuit

breakers at the two ends (although there is no fault), then it is seen that the generator undergoes a

stable transient. Which one of the following waveforms of the rotor angle shows the transient

correctly?r
