How to culculate neutral current in three phase system with unbalance load?
For balanced loading on a 3-phase, 4-wire wye system like this,
the vector diagram would looks like this:
Now follow this Basics of Vector Analysis.
Now for unbalanced loading on a 3-phase, say like this,
the vector diagram would look like this, since there's no C Phase (definitely unbalanced :D):
Now follow this Vector Analysis.
