Wind Turbine Failures during its service life

The main damages during the lifetime of a wind turbine are caused by:

  • general wear and tear,
  • fatigue loads;
  • electrical failure;
  • environmental conditions

General Wear

Delamination can happen in wind blades, where a detachment of the intra and extrados shells
can be seen. Usually associated with leading edge erosion.

Fatigue Loads

It is the phenomenon of progressive rupture of materials subjected to repeated cycles of stress or deformation. A failure in the steel tower can be associated, for example, with an unbalance of the 3 rotor blades.

Electrical Failures

An electrical failure in the wind turbine components can cause the turbine to fire.


Damage from lightning strikes, ice, strong wind, rain, hail, waves and temperature
differences are common to occur in wind turbines.
