Star connection having multiple option of voltages, and
availability of neutral point makes useful for earth fault
relay operation.
Delta connection having requirement of 3 conductors and
itself is long distance, with less current and higher
voltage. So economical way is delta at high voltage side
and star at low/ or consumer end.
