Answer / dkmathur

Because it is a must that we earth the star (neutral) point
at generating point for safety & protection of equipment /
system.

Answer / abhishek sharma

To save copper in tems of money because in star connection
phase vol = line voltage / root three
and to protect generator form earth fault eseily and more
effective by provide generator neautral earhing via
neautral or star point

Answer / suseendran

Because the voltage in each phase will be 1.732 times the
generated voltage, design and insulation becomes simple easier.

Answer / sandeshg

when voltage reduces(because of star) on line the current reduces hence conductor size also reduces. whenever conductor size reduces loss are minimized.

in non technical way how can u define POWER FACTOR??
