Answer Posted / rvg
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.

in electrical control panel. how can i choose the cable rating. (example - 11kw motor, 18-25A mpcb}
need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
