This 1.6 MVA transformer, with an amorphous iron core, was produced in 1998 for use in an engine plant in Waterford, Ireland. The load loss for this transformer is 18.2 kW, and the no-load loss as low as 384 W (80% lower than the typical figure of 1.7 kW for a good transformer).

At 70% loading, the super-efficient transformer saves 13.3 MWh annually, paying back the GBP 2,500 additional investment within 3 years, for an equipment with a 30 years lifetime.

Meanwhile, transformers up to 5 MVA have been produced with amorphous cores in Japan.
