Two additional elements are connected in parallel with arbitrary lines at the load. This paper describes how to determine them by means of graphics. The unbalanced loads are usually classified into the following three kinds: delta connection, V-connection, and single-phase connection. All the connections of the additional elements are illustrated. The balancing conditions and current vectors are given here in convenient form for drawing under the restriction of the symmetrical line voltages. The three conditioned equations for balance are obtained from the manner of connection. The additional elements are a capacitor, a reactor and a resistor. They are represented in admittance. The general compositions and determination of admittances are shown for three cases. Concrete examples of several compositions are drawn. The graphical solutions of the admittance and current vectors are studied. Several compositions for balance are generally possible. It is necessary to choose the most suitable composition among them in practice. A numerical example in the experiment is shown with the vector graphics. This solution is useful in studying the balance of line currents.}, pages = {45--54}, title = {三相不平衡電流平衡化のベクトル図解法}, volume = {28}, year = {1986} }
