Question

What is the range of the exciter voltage in the field coils?

(a) 50-100 V

(b) 150-300 V

(c) 200-400 V

(d) 50-400 V

I have been asked this question by my school principal while I was bunking the class.

This interesting question is from Design of Field Winding in portion Design of Synchronous Machines of Design of Electrical Machines

Answer 1

The correct choice is (d) 50-400 V

Explanation: The minimum value of the exciter voltage across the field coils is 50 V. The maximum value of the exciter voltage is 400 V.
