Analysis of Three-Phase Systems using Space Vectors

Transformation of Phase Quantities into a Space Vector

(1) Drag the red point in the time-behavior applet with the mouse to change the amplitude and the frequency of the zero sequence (offset) signal u0. The signal u0 is added to all three phase quantities, but does not influence the space vector as becomes clear in the complex-plane applet (left-hand).
(2) Drag the vertical red time-marker line in the time-behavior applet to define a point in time. The corresponding space vector is shown in the left-hand applet.
(3) Click the red text "Change u0" in the time-behavior applet to change the time-behavior of the zero sequence signal u0.
