Abstract

The present subject matter is directed to a system and method for operating a wind turbine connected to a power grid. The method includes receiving, via a controller, one or more current feedback signals from one or more electric current sensors of the wind turbine. Another step includes determining, via the controller, if a ground fault is occurring in the wind turbine based on the current feedback signals. In response to detecting a ground fault, the method includes tripping one or more electrical components of the wind turbine and electrically de-coupling the wind turbine from the power grid.
