1)yes you can directly stapdown 132 kv to 11 kv but in
general cases our transimision outgoing feeder may be
66kv,33kv or 11kv thats why we stap down 132/33/11kv ,if 33
kv not required then we can direct stapdown 132kv to 11kv

2)You can certenly step down the voltage from 132 KV to 11
kv , however in Distribution Substation diffrent level of
voltage comes across so as in your case your substation
should have a diffrent outgoin feeders of 33 kv so your
distribution is 132KV / 33 KV / 11 KV...

3)It is only for easy transmission and distribution. 11 kV
is normally used for town distribution. 33kV is used for
transmission to farther areas where the voltage is stepped
down by 33/11 kV sub stations. Normally in 132 incoming sub
stations you will have both 33 kv and 11 kV outgoings
depending upon the location of the 132/33/11 kV sub station.
