Question

What is the rating of the transformer for the voltage of about 11 kV?

(a) 1000-2000 kVA

(b) 100-3000 kVA

(c) 1000-5000 kVA

(d) 100-500 kVA

I had been asked this question in unit test.

I'd like to ask this question from Design of Tank in division Design of Transformers of Design of Electrical Machines

Answer 1

Correct choice is (c) 1000-5000 kVA

To explain: The minimum value of the rating of the transformer for a voltage of about 11 kV should be 1000 kVA. The maximum value of the rating of the transformer for a voltage of about 11 kV should be about 5000 kVA.
