Star and Delta Connections are more importantly give
priority in electrical studies as they are the key
techniques to transmit, distribute and supply power. As the
power developed is in poly phase(mostly 3-ph), the Delta
connections are used to Transmit power in Bulk amount from
remote station and Star connection is used to distribute the
transmitted power as it has got neutral in it.
In poly phase System, Star-delta conversions are done so
that transmission and distribution is made possible with
less losses and more power viz Pdelta= 3 X Pstar.
Similar way losses are 3times in star than delta.
Seeing from harmonics point, both have their own imperatives.
