Q8. A three-phase, 4pole, 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
Answer : Option C
Explaination / Solution:
Q9. Which one of the following statements is true for all real symmetric matrices?
Answer : Option A
Explaination / Solution:
Eigen values of a real symmetric matrix are all real
Q10. 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?
Answer : Option B
Explaination / Solution:
During constant V/f control, at low frequency, the voltage also applied to the induction motor is low. Hence the stator flux also decreases from its rated value.
