Surge Protection Device for Wind Turbine

In wind turbine system, there are many vulnerable electronics equipment which will be damaged by lightning strikes or transient over-voltages, such as:

  • The control system, including sensors, actuators, and the motors for steering the equipment into the wind etc.
  • The electronics, including transformer, frequency converter, switchgear elements, and other expensive, sensitive equipment.
  • Generators, battery subsystem etc.

Properly installed surge protective devices (SPDs) will minimize the potential impact of lightning events in wind turbine.
