generally on the roadside v hav 11kv line which is being
step down to 440v line to line....so any1 can tell me which
type of transformer they r using whether it is star to
delta,delta to star etc...???

Answer Posted / arsenal

i think delta is used in the lv side bcoz in star
connection the voltage phase value will be greatly reduced
as such current is greatly increased so a large conductor
has to be used for transmission which increases the cost
and other losses.
