Web15 mrt. 2024 · Each one of the harmonics in the current has an RMS value, so calculation of the RMS current of the whole signal (as you would need to do when calculating power factor) involves summing the RMS value of each harmonic. I rms = ⎷I 2 dc+ ∞ ∑ k=1I 2 k_rms I r m s = I d c 2 + ∑ k = 1 ∞ I k _ r m s 2 eqn. 3 WebHarmonics are voltages or currents that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency. So given a 50Hz fundamental waveform, this means a 2nd harmonic frequency would be 100Hz (2 x 50Hz), a 3rd harmonic would be 150Hz (3 x 50Hz), a 5th at 250Hz, a 7th at 350Hz and so on.
