1. A wind turbine, comprising:
plural transformers, comprising a first transformer and at least one second transformer, the transformers being connectable to at least one generator, wherein the transformers are arranged within an inside of the wind turbine;
a wind turbine nacelle and a wind turbine tower, wherein the transformers are arranged within the wind turbine nacelle and/or the wind turbine tower, wherein at least two of the transformers are arranged within the nacelle, wherein a transformer center of mass of each of the transformers lies within an annular region between a first cylinder and a second cylinder, each having as cylinder axis a longitudinal axis of the tower, the first cylinder having a radius of between 1.8 and 1.6 times a tower radius at a vertical position of a respective transformer center of mass, and the second cylinder having a radius of between 1.0 and 1.2 times the tower radius at a vertical position of a respective transformer center of mass.
