A conservative formula for determing the maximum avaiable short circuit current (ISCC), avaiable at the secondary of a transformer when the primary source is assumed to be of unlimited capacity is:ISCC = 100% / Zx% x Is, where Is = full load rating; Zx = impedance. A 75KVA transformer operating at 240V with a 2% impedance will have a secondary short circut current of _______.
