II. What is a harmonic waveform? ●Harmonic waveform is a distortion of the normal Sinewave ●It is characterized by its distortion level ● For voltage (THD U - Total Harmonic Voltage Distortion) ● For current (THD I - Total Harmonic Current Distortion) 1.5 1 0.5 0 -0.5 -1 -1.5 = 1.5 1 0.5 0 -0.5 -1 -1.5 Signal with harmonics Fundamental H1 Harmonics H2 to Hn THD (U or I) % = 100 x H1 = 50Hz Hn = n x 50Hz Schneider Electric 6 + 1.5 1 0.5 0 -0.5 -1 -1.5
