purpose of this connections?

Answer Posted / amol moon

In star conection Line voltage= Root3.Phase voltage, and
Line current=phase current, and Nutral is usedfull to
stable to voltage.
In Delta conection Line voltage=Phase voltage, and Line
current= Root3.phase current.when single phasing in delta
he worked v connection and incresed heatting.
