HARMONIC DISTORTION ANALYSIS
ANALYSIS PRINCIPLE: FFT
HARMONIC MEASUREMENT:
• Current: Up to the 50
th
harmonic
• Voltage: Up to the 50
th
harmonic
TYPE OF HARMONICS:
• THD (VL1);THD odd (VL1); THD even (VL1) and also for the other
phases: L2 and L3.
• THD (AL1); THD odd (AL1); THD even (AL1) and also for the other
phases: L2 and L3.
HARMONIC PHASE ANGLE:
• The instrument measures the angle between the single harmonic of
"V" and the single harmonic of "A" expressed as " ° ", making it possible
to know if the harmonics are generated or imported.
• Note: if the system is a 3-wire type, the angle cannot be measured.
HARMONIC DETAILS: For every THD page it is possible to see the
harmonic order.
DISPLAY PAGES: The harmonic contents is displayed as a graph
showing the whole harmonic spectrum.
The information is given also as numerical information:
THD in % / RMS value; THD odd in % / RMS value; THD even in %
/ RMS value; Single harmonic in % / RMS value
OTHERS: The harmonic distortion can be measured both in 3-wire or
4-wire systems. Tw: 0.02 s
