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 / anil
if we need to step down from 33kv to 415V and same is
possible. but the problem is size of transformer due to
heavy current in secondary side. winding is required. this
will make the transformer bulky. not easy to transport to
load center along with various operation problem.

WHICH SIZE A.B.CABLE IS USED FOR 11KV.
we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
