Use of amorphous ribbon and nano-materials in transformer cores

The main purpose of the book chapter is to show comparisons of the performance of amorphous ribbon in transformer cores with that of equivalent, conventional GO steel cores. It should be noted that where direct comparisons are given, they usually refer to results obtained from a limited numbers of cases which often focus on one or two characteristics. Sometimes, performance characteristics are compared under reference magnetising conditions that suit one material better than another.
