3 single phase transformers

[john.merch]

The system is fed by (3) 500kVA single phase transformers. each transformer's impedance is 3.4%, 240/120V.

primiary side: 12470/7200V.

the system is 208/120V and 3 phase.

My question is what the secondary KVA is and its impedance combined.

thank you very much,

Secondary, three times 500 KVA equals 1500 KVA.
PU impedance will be the same.

and the main breaker of the system is only 2000A.

thanks

It appears that the main breaker is sized for 240/416 Volt use.
