16 HARMONICS MENU

This screen displays the harmonics content of voltages and currents

measured by the instrument. This data can be presented in a bar graph ( Fig.

16-1) or in table format

Move through the spectrum using the ◄/ ► buttons to select the various harmonics. Selecting a

harmonic changes it to dark grey and its values are displayed in the table at the bottom of the

screen; see Fig. 16-1 and Fig.16-2.

Fig. 16-1.- Graphic representation of harmonics (as an

example, voltage harmonics in the three phases)

Parameters displayed:

• Harmonic distortion.

• THD according to selection

• THD of even harmonics

• THD of odd harmonics

• Fundamental

• Fundamental %.

Fig.16-2.- Table at the bottom. Shows general data of harmonics and data for a selected

harmonic in the bar graph(in the example, 11th order harmonic)

The dynamic menu options at the bottom of the screen for the "harmonics" menu are:

Button Function Description

Main Menu Brings up the main menu

The

Photo option captures all the instantaneous values

along with the voltage and current wave shapes of the three

phases.

The "Pause" option stops screen refreshing and the "Run"

option restarts screen refreshing, showing the values in real

time.

Lets the user

select the voltages and currents displayed

independently and select the phase or phases to display (or

neutral for current)

Lets the user select the harmonics to be

displayed, up to

n=50 ,in graphic or in table format (list).
