Course Outcomes:

At the end of the course the student will be able to:

• Test DC machines to determine their characteristics and also to control the speed of DC motor.
• Pre-determine the performance characteristics of DC machines by conducting suitable tests.
• Perform load test on single phase and three phase induction motor to assess its performance.
• Conduct test on induction motor to pre-determine the performance characteristics.
• Conduct test on synchronous motor to draw the performance curves.

Conduct of Practical Examination:

1. All laboratory experiments are to be included for practical examination.

2. Breakup of marks and the instructions printed on the cover page of answer script to be strictly adhered by the examiners.

3. Students can pick one experiment from the questions lot prepared by the examiners.

4. Change of experiment is allowed only once and 15% Marks allotted to the procedure part to be made
