Electrical Machine Assembly Drawings Using Design Data, Sketches or Both:

Alternator – Sectional Views of Stator and Rotor dealt separately.

Course Outcomes:

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

• Develop armature winding diagram for DC and AC machines
• Develop a Single Line Diagram of Generating Stations and substation using the standard symbols.
• Construct sectional views of core and shell types transformers using the design data
• Construct sectional views of assembled DC and AC machine and their parts using the design data or the sketches

Question paper pattern:

• The question paper will have two parts, PART – A and PART – B.
• Each part is for 50 marks.
• Part A is for Modules 1 and 2.
• Questions 1 and 2 of PART - A will be only on DC windings or only on AC windings. Students have to answer any one of them. The marks prescribed is 25.
• Question 3 of PART – A covering module 2 is compulsory. The marks prescribed is 15.
• Part B is for Modules 3, 4 and 5.
