Short circuit test of transformer have to do in high voltage side. Because of high voltage side current will be low. So easily we can provide the short circuit testing cable for require rating.

the test conducted on the high voltage side keeping the low voltage side short circuited.

High voltage side is short circuited to calculate the Cu-loos,equivalent resistance and leakage reactance
