Question

The iron losses in a saturated three phase alternator is lesser than the non-saturated three phase alternator.

(a) True

(b) False

I got this question in class test.

My question comes from Cooling (Loss Dissipation) topic in section Rating and Loss Dissipation of Electrical Machines

Answer 1

The correct answer is (a) True

To explain: The non-saturated reactance is greater than saturated reactance. So the reactive losses or iron losses will reduce due lesser contribution of the same.
