A non-contact system and method for transferring an electrical signal or power to a rotating component 2, used for example to power sensors 18 to monitor the condition of wind turbines. A magnetic inductive coupling is generated between a non-rotating transmitter coil 16 and a receiver coil 14, which is fixed to and rotates with the component 2. At least one of the coils 14, 16 encircles a part of the rotating component and its axis of rotation 5. The coils may overlap, and form a coaxial arrangement with the rotating component 2. The mutual inductance between the coils may be independent of the angle of rotation of the component 2. A unit 20 may transfer signals or power from the transmitter coil 16 to the receiver coil 14 using non-resonant or resonant magnetic induction. |
