The nonlinear energy conversion of electronic products can introduce a large amount of harmonic currents into the power grid, resulting in voltage waveform distortion, zero crossing noise, circuit breaker misoperation, and other adverse phenomena. In addition, some devices that frequently switch on and off automatically can cause fluctuations in grid voltage, leading to flickering of lighting equipment and affecting human vision. This system mainly measures the tested equipment（EUT）The interference caused to the power grid under normal working conditions includes two parts: harmonic current measurement and voltage fluctuation and flicker measurement.
