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.
