Harmonics and harmonics can affect the reliable operation of AC powered equipment and systems installed in factories, residential and commercial environments. Harmonics refer to voltages and currents with frequencies that are integer multiples of the operating frequency of the power supply system. Harmonic wave refers to voltage and current whose frequency is not an integer multiple of the fundamental frequency of the power supply system. Harmonics and harmonics are mainly caused by the periodic and linear synchronous operation of equipment or loads with nonlinear voltage current characteristics. Harmonics and harmonics can cause voltage distortion, zero crossing noise, equipment heating, and misoperation hazards. At present, the electrical environment in factories, residential and commercial environments is becoming increasingly complex, and it is becoming more and more important to test the harmonic and harmonic immunity of equipment. This system mainly tests the anti-interference performance of the equipment under test (EUT) against harmonic and harmonic interference, providing a standardized and reliable testing device for evaluating the operational reliability of the equipment under test when subjected to harmonic and harmonic interference.

This system fully meets the requirements of GB/T 17626.13 and IEC61000-4-13 for harmonic and inter harmonic wave immunity. At the same time, it can meet the requirements of voltage fluctuation immunity test in IEC61000-4-14, DC ripple immunity test in IEC61000-4-17, and frequency variation immunity test in IEC61000-4-28
