AMDT is an upcoming technology

Farady amorphous metal distribution transformer is an upcoming technology that reduces losses inside the magnetic core. Although the amorphous materials are still more expensive than standard grain oriented steel, their application can be justified depending on how these losses are capitalized over the lifetime of the transformer. When the transmitted power exceeds around 10 MVA, special designs are required to cope with the mechanical forces of short circuit currents, higher insulation levels and increased cooling requirements. For these ratings, farady 50 kva pole mount transformer are usually used. The insulation between the windings becomes more and more demanding at higher voltages. Furthermore, resonance effects inside the winding itself have to be considered to avoid insulation failures during highly dynamic impulse stresses such as lightning strikes which may reach amplitudes of one to two thousands kilovolt with a 1 μs rise time.
