Abstract
A method for protecting a three-winding transformer of a wind turbine includes estimating, via a controller, an electrical condition of the primary winding of the transformer. The method also includes determining, via the controller, an electrical condition limit of the primary winding. The method also includes comparing, via the controller, the estimated electrical condition to the electrical condition limit. Further, the method includes implementing a corrective action for the wind turbine if the estimated electrical condition exceeds the electrical condition limit so as to reduce the electrical condition within safe limits.
