Harmonic distortion analysis
Analysis principle Harmonic measurement Current Voltage Type of harmonics FFT Up to 50th harmonic Up to 50th harmonic THD (VL1) THD odd (VL1) THD even (VL1) and also for the other phases: L2, L3. THD (IL1) THD odd (IL1) THD even (IL1) and also for the other phases: L2, L3. The instrument measures the angle between the single harmonic of "V" and the single harmonic of "I" of the same order. According to the value of the electrical angle, it is possible to know if the distortion is absorbed or generated. Note: if the system has 3 Harmonic details wires the angle cannot be measured. For every THD page it is possible to see the harmonic order. The harmonics content 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 The harmonic distortion can be measured in 2-wire, 3-wire or 4-wire systems.
