Question

What is the pulsational force produced for 500 MW machine?

(a) 70 kN per m

(b) 60 kN per m

(c) 80 kN per m

(d) 90 kN per m

This question was addressed to me in an interview.

I need to ask this question from Construction of Turbo-Alternators in division Design of Synchronous Machines of Design of Electrical Machines

Answer 1

Correct choice is (c) 80 kN per m

The best I can explain: The generator designed with low voltage gives high currents which produce high pulsational forces. The pulsational forces can be as high as 80 kN per m.
