This case arises only in series dc generator
current should be sent around the poles to magnetize.
this current can the source(generator).
current is passed through poles if it is loaded.
but if it is not loaded current is zero through the field.
load voltage should be zero actually.but this dont
happen.we us egenerator frequently.due to this poles are
partially magnetized this causes some voltage appear called
residual voltage.
i haven't heard about residual current

why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
