3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.

I have 11KV/415V power distribution transformer. I have found unbalance current in LT (415V) side. Also observed that unbalance voltage (3V) at LV side due to HV side unbalance voltage. What should I check for this? Also, the same LV side load can run in balance on captive power.
