Answer / rafi

The star point will have the current equal to the vector
sum of all the threee currents flowing in each winding.
since, the currents in each of the windings will differ
with a phase diff of 120 degress the vector sum will be
zero. provided, the currents in each phase should be equal.

Answer / aung myo myint

yes, by the wave forms all plus and minus are equal.So, you
can get zero. This is the end of electricity point.
