Abstract
The present invention relates to s wind turbine having a power generator for generating power for a first power line of a power grid; said wind turbine comprising a first transformer having a first primary coil connected to said power generator and a first secondary coil connected to said first power line for transforming a first primary voltage (vp1) across said first primary coil to a first secondary voltage (vs1) across said first secondary coil; further, the wind turbine according to the invention comprises a first electric circuit connected to said first primary coil; said first electric circuit having a first switching element for providing a first current path parallel to said first primary coil if said first secondary voltage (vs1) exceeds a predetermined first voltage limit value.
