    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.

    Good Luck
