Short-circuiting techniques to deactivate a generator after a fault

This paper presents a method for protecting an aircraft self-excited d-c generator after either a full-field short-circuit fault or a generator feeder fault has been detected. Protection is afforded, regardless of whether the fault occurs inside the machine or externally. It is also applicable to other types of faults. The method consists, essentially, of purposely applying short circuits between the different generator output terminals, thereby disabling the power-generating capabilities of the machine.
