Single-phase and Phase-to-phase Current Analysis
Selection of three-phase or individual phases L1, L2, and L3, displays:
• The total THD
• The MIN and MAX instantaneous values
• The parameters for the harmonic order selected by the cursor
– Percentage in relation to the fundamental
– RMS value and phase angle in relation to the fundamental component
• MIN, MAX instantaneous values for the selected current harmonic
Power and Direction Flow Analysis
Harmonics on this screen are shown with either a positive or negative
orientation.
Since the bar selected in this example is negative, it indicates that it is a harmonic
from load to source.
TIP
MIN, MAX values are reset each time the cursor position is changed.
