Harmonic distortion test
WebJul 1, 1999 · This may have little impact to the overall harmonic distortion of the voltage sine wave if the power source is lightly loaded. As with voltage waveform distortion, the best location to measure current waveform distortion is at the power source that feeds the equipment location (i.e., isolation transformer or main service entrance). WebMar 15, 2024 · Total harmonic distortion (THD) is an important aspect in power systems and it should be kept as low as possible. Lower THD in power systems means higher power factor, lower peak currents, and …
