Embodiment Construction

[0022] The illustrations in the figures are schematic. It is to be noted that in different figures, similar or identical elements are provided with the same reference numerals.

[0023] figure 1 A wind turbine 1 for generating electrical power is shown. The wind turbine 1 comprises a measuring device 100 according to the invention for measuring electromagnetic waves. The wind turbine 1 comprises a tower 2 mounted at one bottom end on the ground 8 . At the opposite top end of the tower 2 a nacelle 3 is mounted. The nacelle 3 houses a generator of the wind turbine 1 (not shown in the figures). Between the tower 2 and the nacelle 3, yaw angle adjustment means (not shown) are provided, which enable the nacelle to rotate about a vertical yaw axis Z. The wind turbine 1 further comprises a wind rotor 5 having one or more rotating blades 4 (in figure 1 In the perspective view of , only two blades 4 are visible). The wind rotor 5 is rotatable about the axis of rotation Y to tran...

Abstract

Wind turbine (1) including a tower (2), a nacelle (3), at least one rotatable blade (4) and a measuring apparatus (100) for measuring electromagnetic waves including at least one electromagnetic waves sensor (101, 102, 103), wherein the electromagnetic waves sensor (101, 102, 103) includes at least one leaky feeder (20).

Description

technical field [0001] The invention relates to a wind turbine comprising a measuring device for measuring electromagnetic waves. The measuring device can be used to detect and locate lightning strikes. Background technique [0002] Sensors for measuring electromagnetic waves are often provided in wind turbines. Non-contact devices such as antennas, shunts or Rogowski coils can be used for this purpose. This device can be used to detect and measure electromagnetic waves emitted by adjacent cables, sparkling relays and lightning strikes. [0003] Therefore, the solutions described above are not yet optimal for a number of reasons including limited frequency range, lack of robustness and high cost. Contents of the invention [0004] The scope of the present invention is to provide a simple, efficient, robust and cost-effective measuring device for measuring electromagnetic waves by solving the inconveniences mentioned with reference to the prior art cited above. [0005]...
