What is the difference between CRNO and CRGO in an
transformer and what is the advantages of these two.

Answer Posted / rameez raja kaleel

The correct explanation is for cold rolled grain oriented
winding have the flux density is saturated.we know the flux
density B= flux/area since Bis constant the flux is also
constant there will not be any change in the frequency
since E/F is directly propotional to flux hence the losses
in the windings has been reduced,.but i have no idea on CRNO
