Abstract
A method and system for responding to a fast trip protective element trip in a generator system that re-excites the generator when a fast trip protection element trips and determines whether the generator immediately retrips the fast trip protection element, thereby determining whether a fault is located in the generator or in an attached load. If it is determined that the fault is located in the load, the system re-excites and reconnects the load after disabling the fast trip protection element for a specified period to allow for the load to clear its fault.
