The magnitude of short-circuit overcurrent is normally less than the magnitude of ground-fault overcurrent available from the same transformer.
A ground fault can occur across two or more transformer windings in a 3-phase AC electrical-power distribution system or across the full winding in a single-phase AC electrical-power distribution system.
A short circuit normally affects only one winding in the transformer which supplies power to the faulted condition in a 3-phase AC electrical-power distribution system or one-half of the secondary winding in a single-phase AC electrical-power distribution system.
