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 / prithvi narayan sinha
While in Star connection we can reduce the line voltage by
57.7% due to the fact that we get the line voltage as 1/sqrt3
of the phase voltage ,hence reduction becomes easier and
convenient too. while in delta we get the line voltage=
phase voltage.
