Higher rated machine should be set at less droop than that
of lower rated machine,for equal load sharing and smooth
operation of system.If both machine ratings are equal,droop
should be equal.

While performing stability test of differintial cts how to know the voltage and current on both side of the transformer?

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?
