Autotransformers are specific by having two coils, while one has dual use. Autotransformers are smaller, lighter and having lower losses. Reduced losses increase efficiency. The reduced weight and size of the autotransformers creates more favourable conditions for its delivery to the installation site.
ETD offers autotransformers with output up to 450 MVA and voltage 420 kV.
