Question

What is the formula for height of the single phase core type transformer?

(a) height = height of the window – height of the yoke

(b) height = height of the window + height of the yoke

(c) height = height of the window – (2*height of the yoke)

(d) height = height of the window + (2*height of the yoke)

I had been asked this question in quiz.

The above asked question is from Overall Dimensions in chapter Design of Transformers of Design of Electrical Machines

Answer 1

Correct option is (d) height = height of the window + (2*height of the yoke)

Explanation: The height of the window is first obtained. Next, the height of the yoke is calculated and it is multiplied by 2. Addition of both the values gives the height of the single phase core type transformer.
