    Jun 20 2017 · Every wind turbine has an anemometer that measures wind speed and a wind vane to keep track of the wind s direction. See if you can find them toward the end of the scene of this 360° Wind Turbine Tour video.. When the anemometer registers wind speeds higher than 55 mph (cut-out speed varies by turbine) it triggers the wind turbine to automatically shut off.
