See Second Zero expansion manual.
11. HARMONICS
The control unit performs a calculation of the different voltage and current
harmonics. The information shown is:
•
Spectrum graphic in frequencies
•
Values in % of the harmonic components up to 20
•
Total harmonic distortion (THD) and total harmonic distortion plus
noise (THDN) in %
Using the arrow keys (+) (-) the signal to be analysed is selected (VG1, VG2, VG3,
VR1, VR2, VR3, I1, I2 or I3). To display the harmonic press the confirm key (v).
> Analysed signal: selection with cursors (+) (-).
