A wind turbine, comprising;
- a hollow tower carrying a nacelle, and
- at least one power electronics component emitting electromagnetic waves during operation,
- wherein the tower acts as a wave guide for an electromagnetic wave generated by the power electronics component,
- wherein the tower comprises at least one absorber element at least reducing the transport of the electromagnetic wave of the power electronics component along the tower, and
- wherein the at least one absorber element is provided in an area surrounding a position of maximum electrical field amplitude, neglecting the at least one absorber element, of the electromagnetic wave for at least a wavelength of the electromagnetic wave in the tower.
A method for improving an electromagnetic compatibility of a wind turbine having a tower carrying a nacelle and at least one power electronics component emitting electromagnetic waves during operation, wherein the tower acts as a wave guide for an electromagnetic wave generated by the power electronics component, the method comprising:
- providing at least one absorber element in an area surrounding a position of maximum electrical field amplitude, neglecting the at least one absorber element, of the electromagnetic wave for at least one wavelength of the electromagnetic wave in the tower, such that the at least one absorber element reduces the transport of the electromagnetic wave of the power electronics component along the tower.
