Question

Compiling an Electrical Machines laboratory report.

Do take your time if you have to. I have 5 hours.

Kindly find attached documents.

 

3. DISCUSSION:
1. What is the nameplate reading on the machine? What inferences can be drawn from
it?
2. What is the real and reactive power consumed in this test?
3. From the values in the tables above, calculate the parameters of the approximate
equivalent circuit of the motor.
4. What is the power factor of the machine both at No- load and Blocked rotor Test.?
Comment on their values.
5. What should be the no load current of an induction motor?
6. Even though there is no-load, why wattmeter reading is not zero?
7. Comment on the slip of the machine when operated at rated voltage.
8. How to obtain the no-load input power to an induction motor when two-wattmeter
method of measuring power used?
9. Can a three phase induction motor be started from a single phase supply?
10. Which loss in the machine is significant in no load test and why?
11. Calculate for rated motor load and the efficiency.
