  • Page 5: Introduction

    Hybrid XT Vane INTRODUCTION The NRG Systems Hybrid XT vane is an electrically heated wind direction sensor designed for wind turbine control and wind resource assessment. The sensor is mounted to the turbine nacelle or meteorological mast and provides an electrical output signal relative to wind direction.

  • Page 6: Vane Operation And Considerations

    Hybrid XT Vane Head Damping The Hybrid XT Vane has damping in the head to reduce overshoot and oscillation behind the turbine rotor. One result of this is that the frequency response has been lowered slightly. This may, in some limited circumstances, require a slight adjustment to the turbine controller settings when retrofitting a Hybrid XT in place of an IceFree 2, IceFree 3, or an original Hybrid.
  • Page 7 NRG Product Manual Hybrid XT Vane Heater Operation The heat source for the Hybrid XT is a self-regulating, constant-temperature heater. Constant heating prevents condensation and corrosion and maintains proper bearing temperature for consistent performance and transfer function. In severe wind and icing conditions, the Hybrid XT draws more power to help remain clear of ice. As conditions improve, the Hybrid XT draws less power.
  • Page 8 On the NRG Systems -cable assembly for the Hybrid XT Turbine Control Sensor, the shield is available for connection at both ends. If the sensor end is not to be connected, cut off the shield wire at the sensor end before installation to prevent accidental contact to the sensor mount.

  • Page 13 NRG Product Manual Hybrid XT Vane The Hybrid XT sensors have four ridges running vertically inside the body's lower end as shown in the picture below. These ensure that the sensor mounts securely on the mounting mast. If attaching the shield to the ground screw, make sure that it does not interfere with the mounting ridges by running it straight down the mast from the connector to the ground screw.
  • Page 14 There will be some drag as the o-ring seal and the connector pins engage. Tighten the bolt using a 10 mm wrench to 7 N-m (5 ft-lbs). Replacement washers, nuts and bolts can be ordered from NRG Systems (part #4422).

  • Page 16: Grounding And Bonding Hybrid Xt™ Sensors For Over-Voltage Protection

    PROTECTION Introduction The purpose of this document is to outline NRG Systems’ recommended practices for wiring, grounding, and bonding of Hybrid XT™ turbine control sensors. The goal is to provide the best possible protection against direct and indirect lightning damage for both the sensor and the interconnected turbine systems.
  • Page 17 NRG Product Manual Hybrid XT Vane about preventing ground loops. NRG Systems supplied cables provide a shield at the sensor end. If your LPS design does not use this shield drain, trim it off to prevent short circuits. 5. Run the sensor cabling in metallic raceway or conduit. Bond the raceway or conduit to the LPS at both ends.

    If you were to look at the signal on an oscilloscope, you would notice that the rising edges fluctuate back and forth from cycle to cycle. This is normal and was designed this way for Renewable NRG Systems factory use. This will not affect your frequency counter in any way.

    NRG Product Manual Hybrid XT Vane APPENDIX B: FG# 5762 – HYBRID XT 4-20 MA OUTPUT VANE Output Circuit Operation The Hybrid XT 4-20 mA Turbine Control Vane provides an industry standard 4 to 20 mA output signal sourced by the sensor.

  • Page 25: Appendix C: Fg# 7894 - Hybrid Xt Push-Pull Vane

    Output Circuit Operation The Model 7894 Push-Pull Hybrid XT vane was designed as a direct replacement for 1- or 2-Channel NPN-type IceFree3™ wind vanes. It provides two output signals, in push-pull format. These outputs can source current when on and sink current when off for compatibility with a wide range of controller inputs, including those designed for existing NPN or PNP sensors.
  • Page 26 NRG Product Manual Hybrid XT Vane dithered signal is switching on and off with a ratio of 50%. As the wind varies to the right or left, the sensor varies the on/off ratio to simulate an under-damped vane’s mechanical dithering.

  • Page 27: Appendix D: Fg# 9362 - Hybrid Xt 4-20Ma, Counter-Clockwise Vane

    The Hybrid XT 4-20 mA Turbine Control Vane provides an industry standard 4 to 20 mA output signal sourced by the sensor. The output range of 4 to 20 mA corresponds to 0 to 360 degrees. The output of this Hybrid XT vane increases from 4-20mA proportionally as the sensor swings in a counter-clockwise rotation, opposite the FG #5762 version.

  • Page 28: Appendix E: Fg# 9363 - Hybrid Xt Push-Pull, Active-High Vane

    Output Circuit Operation The Model 9363 Push-Pull Hybrid XT vane was designed as a direct replacement for 1- or 2-Channel PNP-type IceFree3™ wind vanes. It provides two output signals, in push-pull format. These outputs can source current when on and sink current when off for compatibility with a wide range of controller inputs, including those designed for existing NPN or PNP sensors.
  • Page 29 The Hybrid XT turbine control vane head maintains a stable output position that tracks the wind direction more accurately and varies much less than under-damped sensors. For compatibility with controllers that are expecting a dithered signal, the electronics of the Model 7894 Push-Pull Hybrid XT Vane creates a compatible dithered signal. When the XT senses the...
