EVT Replacement Technology: Gearboxes have been failing in wind turbines since the early 1990s; barely a turbine make has escaped. The problem reached epidemic proportions with a massive series failure of gearboxes in NEG Micon machines. At the time, the NEG Micon brand was the most sold wind turbine in the world. The disaster brought the company to its knees; it was taken over by the world’s largest wind turbine manufacturer, which still is challenged by gearbox failures.
When a gearbox fails, the Rotor may still continue to turn, and all the power generated by the rotor is converted to heat. The result is often a fire which destroys the wind turbine.
