A sensor arrangement for sensing bending moments in an elongate component (e.g. a blade of a wind turbine). The sensor arrangement comprises a measurement rod extending at least a predetermined distance parallel to the direction of elongation of the elongate component and transverse to the axis of bending. The sensor arrangement further comprises a fixing element attached to a distal end of the measurement rod, the fixing element being configured for fixedly attaching the measurement rod to a surface of the elongate component, and a support element attached to a proximal end of the measurement rod, opposite the distal end, the support element being con- figured to be fixedly attached to the surface and for sup- porting the measurement rod such as to allow axial displacement thereof. The sensor arrangement further comprises a dis- placement sensor (e.g. inductive sensor), disposed adjacent and spaced apart from the proximal end of the measurement rod, the sensor being configured for outputting a signal indicative of the axial displacement of (e.g., a metal tip of) the measurement rod. The measurement rods are made of the same material (e.g. fiberglass) as the elongate component. Preferably three or four of the sensor arrangements are ar- ranged (equally) angularly spaced around an internal peripheral surface of the blade root. An elongate component, sensor system and wind turbine are also disclosed.

The invention relates to a tower for a wind turbine and to a cable guide therefor, wherein a nacelle for the wind turbine is arranged on the tower such that it can rotate by means of the azimuth bearing about a vertical axis which runs in the longitudinal direction of the tower. Current-conducting cables are routed in the tower of the wind turbine out of the nacelle from electrical components to the ground. The tower has at least two bundling devices which are suitable for joining the individual cables which run longitudinally in the tower together to form a cable bundle with the cables fixed with respect to one another. The bundling devices are attached to the cables between an upper and a lower area of the cable bundle. In this case, geometric configuration of the bundling device ensures that at least between three cables it is not below a specific minimum distance.
