1:--- actually we used delta -star connection in power
distribution transformer to provide the returning path of
current,because connected load does not balanced so
returning current goes to transformer star point through
neutral wire which always earthed.
2;---In distribution load is being different type like
single phase three phase etc so we have required neutral for
single
phase load which is only possible in star connection.
