The chart displays the vectors Va, Vb, and Vc with an origin at the neutral point N. Va, Vb, and Vc form a closed triangle with the centroid G. The symmetrical component vectors V0, V1, and V2 are displayed and share an origin at G and a reference real axis parallel to Va-G. The angle Φ12 between V1 and V2 is displayed. Va, Vb, Vc, and N can be moved freely to affect the symmetrical component vectors. The point H represents the neutral position where 0 phase unbalance occurs and is also the circumcenter of the Va-Vb-Vc triangle. 5 different types of unbalance values are displayed on the left
