Answer / arun

yes. by using step down transformer (33Kv to 430V

Answer / jeff

yes you can, normally they use 33kv/11kv tranformer because
the side have more than 2 sustation and need more
transformer, for the 33/.433kv transformer is expensive
than 11/.433 transformer. so they just step down the HT
33KV to 11KV first than supply to two substation by using
11/.433kv transformer

Answer / engineering.force

One more important point you all have missed is about the
secondary winding current. If we step down from 33/11 KV the
secondary current will be less than if we step down from 33
KV/440 V, hence the secondary winding has to be accomodated
with above high value of current. This will lead to increase
in winding diameter, thus increasing the overall size of the
transformer, and also increase in the heating of the
secondary, thereby reducing the efficiency of the
transformer. And hence costly. So taking in the above
considerations, we have to design the step down voltage
level so as to make it cost effective and economical.

Answer / puneet kulshreshtha

IN PAST MANY OF TIMES WE USE 33/.430 KV S/S

BUT IT IS VERY EXPENSIVE SO WE USE 11/.430 S/S FOR EASY
COST AND TRANSPORTATION

Answer / gsamguna

we can use 33kv/ 440 transformer
who said cannot
if u want 33kvto 440 u want to install two transformer
33kv/11 and 11/440v
this s stupit answer ..
sure we can use 33kv/ .44 kv directly step down

Answer / ghanshyam singh

it will be dangerous as the transformers which converts 11
kv to 430 volts cant be installed in colonies

Answer / arup

for the industrial purpose we have to step down the voltage from 11kv to 430 v.no we can't step down 33kv to 430v
