Introduction
NRG IceFree3™ Vane (Heated)
The NRG IceFree3™ yaw vane is an electrically-heated wind direction sensor designed for wind turbine control at
ice-prone sites. The vane base is fixed to the turbine nacelle, with relative “north” facing directly toward the
blades. Rotation of the vane indicates yaw errors and provides output signals relative to the fixed vane base.
The IceFree3™ is reliable in heavy and light winds. It is rugged enough to accurately measure winds in excess of
90 meters per second (200 miles per hour), yet its low moment of inertia allows it to respond to winds as low as
2.0 m/s.
NRG Turbine Control Vane (Unheated)
The NRG Turbine Control yaw vane is a rugged wind direction sensor designed specifically for wind turbine
control. The vane base is fixed to the turbine nacelle with relative “north” facing directly out toward the blades.
Rotation of the vane head interrupts optical sensors and indicates yaw errors by providing output signals relative
to the fixed vane base.
The NRG Turbine Control yaw vane is reliable in heavy and light winds. It is rugged enough to accurately
measure winds in excess of 90 meters per second (200 miles per hour), yet its low moment of inertia allows it to
respond to winds as low as 2.0 m/s.
