Wind Turbines automatically shut down when the wind speed gets to at least 55 MPH to prevent damage to the wind turbine.
If the wind turbine spins too fast then it could produce too much voltage and destroy the generator and components and also destroy the blades etc.
So during high wind events the wind turbine must shut down to prevent costly damage.
To prevent damage to the wind turbine the wind turbines are shut down at wind speeds of 55 MPH.
Wind turbines are made so that the wind turbines shut down automatically once they get to a wind speed of 55 MPH.
High wind speeds can cause the wind turbines to generate too much electricity and can cause the wind turbine blades to break off as well.
So to prevent damage the wind turbine blades shut down at 55 MPH and stay shut down until the wind speeds drop below 55 MPH.
Wind turbines cost a lot of money so they must be protected from damage.
The maximum wind speed for wind turbines is around 30 to 40 miles per hour and anything above 40 miles per hour wind speed could potentially cause damage to the wind turbines.
When wind speeds get to 50 MPH the wind turbines are shut down to prevent damage because at 50 MPH wind speeds and above severe damage can be caused to the wind turbine.
The high wind speeds can cause the blades to fly off through the air or burnout the generator by creating too much electricity.
So when the wind speeds are forecast or get to 50 MPH the wind turbines are shut down to prevent damage.
The amount of copper that a wind turbine contains varies due to the size of wind turbine and how many megawatts the wind turbine electric generator is.
The average wind turbine however contains around 3.6 tons of copper per megawatt.
Copper costs around $7,000.00 per ton so the average wind turbine that is used to generate electricity from a wind farm contains around $20,000.00 of copper per wind turbine.
