Answer Posted / iamdon
star coonection reduces the voltage appering across each
phase by root 3 times.It means we need to design the
insulation for lower voltage which is economical.Also due
to reduced voltage reduced currrent will flow through
winding so less loss so less heating of winding so less
cooling requirement for keep the temperature rise within
limit.
All these beauty will lost in delta connection.So delta is
not preferred..
