A system and method for subtransient current suppression in a power system. A generator is configured to provide an output current to a power distribution system. A current sensor is configured to sense the output current. A switch is configured to direct the output current to ground when the switch is closed. A controller is configured to close the switch for a time delay in response to identifying a level of the output current that is greater than a threshold level and to automatically open the switch in response to identifying an end of the time delay.
