Critical Clearing Angle

The critical clearing angle is defined as the maximum allowable variation in the load angle curve during a fault, beyond which system synchronism is lost if the fault is not cleared. In essence, when a fault occurs in an electrical system, the load angle begins to increase, putting the system at ris
