Unbalance neutral current in a 3 phase system

[LarryFine]

for those who don't know, a quadrilateral is a four-sided, closed polygon.

I thought it was an underground three-phase service.

I asked Smart to post this diagram in order to illustrate the simplicity of the method. That is, he subtracted the three balanced currents, 46A, leaving only the two unbalanced components, 3A and 1A. Then, the phasor which closes the triangle is the neutral current, In.
