High power distribution auto-transformer
200 MVA
Siemens PS Power Transmission Solutions
In the power range above 200 MVA, generator and network intertie transformers with off-load or on-load tap changers, or a combination of both, are recommended. Depending on the onsite requirements, they can be designed as multiwinding Power Transformers or autotransformers, in 3-phase or 1-phase versions. Even with ratings of more than 1,000 MVA and voltages up to 765 kV (800 kV), the feasibility limits have not yet been reached. We manufacture these Power Transformer units according to IEC 60076 as well as other international and national standards (e.g., ANSI/IEEE).
