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 / anonymous
11kv is basically for primary distribution say to a large
factory. so at a substation, stepping down to 11kv for such
use and further stepping down to 415V for residential areas.
