Why we should use delta connection in primary and star
connection in an distribution transformer, which converts
400v a.c. voltage to 33kv.

Answer Posted / premsingh

we use delta connection in prymary becouse in prymary we
need step up the voltege & in delta connection line voltage
is more then phase voltage & we use star in secondry bcoz
in star connection provide us nutral which is nessery for
distibution because all home applances work with phase &
nutral so we use star connection in distribution end.
