Figure 3-10
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 apparent power is lower than x.xxx VA 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
parameter.
If one of the spectral lines ±5 Hz of the harmonic frequency is greater than 2 % of the RMS value of the
harmonic, the corresponding value is displayed in blue as an indication.
The sign of the active power of the single harmonic determines the power-flow direction:
•
Positive sign: from the supply system to the demand
•
Negative sign: from the demand to the supply system
