Complex Vectors in 3-Phase Circuits

To provide additional bridges between the fields of mathematics and electrical engineering is the main object of this paper, which is a sequel to a previous work on dyadic algebra. The paper includes an application of Gibbs's directional ellipse to 3-phase circuits, a treatment of symmetrical components by using the isoclinic unit vector and 2 circular complex vectors and an exposition of dyadics as appplied to in 3-phase symmetrical machines.
