the ht motor connection in star because it is easy and
cheaper than delta connection in high voltage and star
delta connection not used in this system .
and the best question here why the ht capacitor of power
factor connection star not delta although the delta
connection is more economecal than star. we need in star
three times farad(reactive power) of ccapacitor than delta
but we connection star not delta because the same reason in
ht motor.
but the ht transformer some times it is necssary to
conection the primary or the secondary or both delta
accrding to the requirment of network.
