Dear Sir,
How to calculate 3phase ,11kv/415v,Distribution transformer for single phase,230 volts 1000kw Total connected load.

Watch out for unbalanced loads. If unbalanced, the transformer size will have to be (3)*(max. kva/Phase).

See thread238-261481 for more explanation.

Why use a 3Ø transformer for a 1Ø load? If there are several 1Ø loads, balance them among the phases. If there is only one 1Ø load, use a 1Ø transformer.
