Answer Posted / sunil guru
Star - Star bcz.. it has a point at center which can be
used as a neutral or can be grounded,
but in case of star-delta there is no path for ground
return current during short circuit..an the circulating
current will flow inward itself and can damage the winding..
for any disagreement mail me at parmar20072008@yahoo.com
