An apparatus for transferring data between bodies undergoing rotation is provided. The bodies in question may be wind turbine components such as a turbine drive shaft and a stationary part of the turbine, such as nacelle gearbox. A data or control signal can therefore be transmitted between a rotating member, such as a turbine blade, and equipment in the nacelle. The apparatus comprises two members that are placed adjacent and opposing one another, and on the opposing surface of which a number of electrical paths are provided. The closed electrical paths do not enclose the rotational axis. At least one of the loops is energised with a carrier high frequency oscillating signal to create a flux that threads the loop on the opposing member. Modulation of the carrier frequency allows signals to be transmitted between the members. |
