Surge Protection for Wind Turbine

Wind Farms are in open and exposed environment and the tall windmill is highly prone to lightning damage and thus must be well-protected against it. After lightning receiving / down conducting / grounding, it is necessary to install SPDs on:

  • stator/rotor of the generator
  • transformers of different levels
  • controlling and communication signal cables
