Question

Which of the following mentioned losses occur in a transformer?

(a) Hysteresis losses; Eddy current losses; Dielectric losses; Stray load losses

(b) Hysteresis losses; Eddy current losses;

(c) Dielectric losses; Stray load losses

(d) Hysteresis losses; Eddy current losses; Stray load losses

I have been asked this question during an interview.

My doubt is from Transformer Losses and Efficiency in portion Transformers of Electrical Machines

Answer 1

Correct answer is (a) Hysteresis losses; Eddy current losses; Dielectric losses; Stray load losses

The best explanation: Hysteresis losses-due to magnetic material; Eddy current losses-on the core area; Dielectric losses- due to insulation material; Stray load losses- due to leakage through the parts of the transformer.
