7.1.4 CURRENT HARMONICS

In the current harmonic decomposition screen, numerical values are shown for the phase 1

harmonic decomposition.

The values are displayed in columns of 10, and the most important values are shown on the

left side of the screen as a %. These values are :

I1 fund

:

Phase 1 fundamental value.

I1 thd

:

Phase 1 harmonic distortion rate value, expressed as a %.

Odd I1 thd

: Value of the harmonic distortion rate for the phase 1 odd harmonics, expressed

as a %.

Even I1 thd

: Value of the harmonic distortion rate for the phase 1 even harmonics,

expressed as a %.

The bottom menu offers the following options:

Info

: This displays the system information screen (Section 6.1.1.1., System Information).

Next

: This displays the screen of values corresponding with the next phase. This is a rotating

menu that contains phase 1, phase 2, phase 3 and neutral.

Values provided on this screen are real time values that correspond using the mean value

calculated from the signal samples.

Grap

: This graphically displays the harmonics spectrum.

The phase displayed on the graphical interface corresponds to the one that was

selected for numerical values on the previous screen. The options permitted by the

graphical interface include: changing between viewing all harmonic

values, odd harmonic values and even harmonic values.
