Question

What should the magnetic path be in order to reduce the core reluctance?

(a) length of the magnetic path in core should be low

(b) length of the magnetic path in core should be medium

(c) length of the magnetic path in core should be high

(d) length of the magnetic path in core should be very high

I got this question in quiz.

My query is from Design Principles in division Design of Current Transformers (CT) of Design of Electrical Machines

Answer 1

The correct option is (a) length of the magnetic path in core should be low

For explanation: The length of the magnetic path in core should be as small as possible. This reduces the core reluctance of the current transformer.
