The characteristics of large amorphous core transformers, such as %IZ, core loss and load loss, are discussed in design examples considering the properties of core materials. Some desings of 5000 kVA transformers with amorphous cores are compared with Si-steel core transformers, and the measured characteristixs of a 100 kVA trial transformer are described. The core losses of the composite amorphous and Si-steel cores are also described.
