Answer / pallamraju
in star line current =phase current
line voltage =1.732* Ph voltage.
if we connected in star there is no change of current parameter.insulation level can be minimized.hence size of the motor will be reduced.if in delta it will be more.that's why all HT motors ,syns motors & generators in star connected system.

Answer / gunasekaran
1.we can use less no of turns for same voltage level
2. we can put less insulation.

Answer / giri
Starting current is reduced 1/3 times during star connection
starting since voltage also reduced by the same proportion
.U can remind in star-delta connection starter.

Answer / n. gopal krishna (hf)
In star line voltage =1.732*phase voltage &In delta
Vl=Vp.so we can not provide much insulation in delta
connection. we cannot use also differtional relay in delta.

Answer / s c budhiraja
To reduce starting current as well as avoiding star -Delta
starter, the motor stator is connected in Star.
