Question

There is a 10 KVA, 2000/200 V, single phase transformer operating at 50 Hz. Maximum flux linkages in secondary will be?

(a) 0.9 AT

(b) 9 AT

(c) 1 AT

(d) 0.09 AT

I have been asked this question in semester exam.

The doubt is from Transformer as a Magnetically Coupled Circuit in division Transformers of Electrical Machines

Answer 1

The correct choice is (a) 0.9 AT

The explanation: Flux linkages on secondary = N*φ = E/(4.44*f)

                           = 200/(4.44*50)  = 0.9 AT
