CRGO Laminations in a transformer are used to minimize __________

A. eddy current loss

B. hysteresis loss

C. both eddy current and hysteresis loss

D. ohmic loss

This question was addressed to me in homework.

My question comes from Equivalent Circuit of Transformer in portion Transformers of Electrical Machines

Right choice is C. both eddy current and hysteresis loss

For explanation: CRGO steel is rolled grain type domains which not only help for faster reversals but also the reduction of eddy current losses.
