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.

i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….
