If a 3 phase transformer is a 500 kva using the formulae
500kva= 500000/433 x 1.732 = 666.71amps does this mean that
each phase on the secondary side is 666.71

Answer Posted / k.prakashchandra
The VA per phase is (500/3 KVA) 166.67 x 1000 , phase
voltage is(433/1.732) 250 V.Then current in each phase is
166670/250= 666.68 A

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.
