Question

The core length should be high to obtain high short circuit ratio.

(a) true

(b) false

I have been asked this question in an online interview.

Question is from Separation of D and L, Standard Frames in section General Concepts and Constraints in Design of Rotating Machines of Design of Electrical Machines

Answer 1

Correct answer is (a) true

For explanation: The core length is directly proportional to the short circuit ratio. If high short circuit ratio is required, high core length should be used.
