we have two 11/.433 kv. distribution Transformer rating as 1000 kva & 500 kva , i wants to run..

Answer / kandasamy

Since both the trasformers are identical impedance , The
load sharing will be exactl equal OF TOTAL (LOAD)POWER.
Load sharing of transformer A= Power x(ZB/ZA+ZB).
Load sharing of transformer B= Power x(ZA/ZA+ZB).

Answer / virendra

As mentioned if the capacity, the vectror group ,
Impedance is equall you can connect both the transformet
in parrel just make sure that the Phase sequence for both
the transformer is same at the time of parallel & as the %
impedance is same the laad sharing will be equall.

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.
