in our sub station why we step down firstly 33kv\11kv then
11kv to 430v. can we direct step down 33v to 430.v.

Answer Posted / anas

cuz u have to pass it first on substation (distribution
boards) to make it easier cut and start the current in case
of any fault happened and if u didnt do that damage we will
be easy not just easy very very very easy and cause the
transmission stations to damage and u will loss power when
u transform from 33kv to 430v directly ahuge amount of
current will be in the cable that means very huge cable
besides loads alaways
