why we step down voltage level from 33kv to 11kv and 11kv
to 415v.Instead we can step down voltage from 33kv to 415v
directly using single transformer.

Answer Posted / raviteja nowduru
a)in a 33/11 kv transformer has more current on secondary.if
it is 33/.415 kv much more current in secondary .so
conductors on secondary should be designed to 415v ,and for
a large current.
But if it is 33/11kv transformer they will be distributed
to various 11/.415 kv transformers.so current capacity of
conductors are decreased.
