THDI – Total Harmonic Distortion of the current

0064 RMS value of the current

0066 Total Harmonic Distortion of the current

0067 RMS value of the current

The rms value of the current (Irms) is a function of the Total Harmonic Distortion of the current (THDI) and the rms value of the fundamental component of the current (I1,rms).
