How can I size a three phase transformer for single phase loads?

Hi,

I have 230Kw single phase balanced load(220V), how can I size a three phase transformer(20000/400V) for those?

loads data:

Lighting(sodium vapor)

power facvtor: 0.9(with compensator capacitor)

starting current=1.5* I

If you have 3 phase plus neutral in the output (star connection) you can use a transformer of 3 times rated capacity
