Vector Function

Introduction to vector display interface

Coordinate of maximum value: display the maximum U, I or UI values of the

phases A, B and C.

Vector value of single harmonic phase: display the single harmonic component

and phase value of each phase. The phases A, B and C are respectively in

yellow, green and red. The user can rotate the knob to select the desired single

harmonics.

NOTE

 The vector function is valid only in the three-phase mode.



The phase parameters in the figure correspond to those in the harmonic

function. The vector diagram is another kind of demonstration of

parameters in the harmonic function.
