2.3 Measurement and Evaluation Functions
[sc_harmonics power direction, 1, en_US]
Figure 2-37
The harmonics power function supports to hide harmonics that you are not interested in from the display
table. You can set the value from which amount of the harmonics power is hidden on the display via the
parameter Hide harmonic when magnitude is lower than x.xxx W displayed above the measurement table.
If you press the ENTER key, the value set for this parameter is active. It is not necessary to activate the param-
eter.
The sign of the active power of the aggregated harmonics shows the direction:
•
Positive sign: demand side, shown in green on the HTML page
•
Negative sign: supply side, shown in blue on the HTML page
Evaluation of Voltage Interharmonics, THD and K-Factor
To display the measured values in the Value view and evaluation tab, proceed as follows:
•
In the navigation window, select Operational Parameters → Process connections → Voltage interhar-
monics. You can select to view the phase-to-phase voltages (ph-ph) or the phase-to-neutral voltages (ph-
N) when the network type is 4-wire, 3-phase, unbalanced.
