The following phasor diagram illustrates the system vector diagram where the
setting is selected as "Wye". By definition, power factor is the cosine of
CONNECTION TYPE
the angle between the phase to neutral voltages and the corresponding phase current. In
this example, 18.2° is the angle between Van and Ia, Vbn and Ib, and Vcn and Ic. The
phase-to-phase quantities are not shown in the
and the EnerVista 469 Setup software. However, they are shown on the following figure.
