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.

UG cable sizes were specified in sqmm. But practically its not coming to mesure. What's the reason for that? And how they specify the size of the cable?
