The present subject matter is directed to a method for managing and/or categorizing trip faults of an electrical component, such as power converter, of a wind turbine. The method includes receiving, via a local controller of the wind turbine, an indication of at least one trip fault in the electrical component of the wind turbine. The method also includes determining, via the local controller, a unique identifier for the trip fault. More specifically, the unique identifier contains information regarding a type of the trip fault and at least one of an origin or a cause, of the trip fault. Further, the method includes sending, via the local controller, the unique identifier to a supervisory controller of the wind turbine. Thus, the method also includes implementing, via the supervisory controller, a control action based on the unique identifier.
