Electromagnetic interference, also known as EMI, refers to any electromagnetic phenomenon that occurs during conduction or electromagnetic field accompanied by voltage or current, which can reduce the performance of a device, equipment, or system, or may have adverse effects on organisms or substances. Electromagnetic interference is also a major issue in frequency converter drive systems Electromagnetic anti-interference, also known as EMS, refers to the ability of machine equipment and systems to have a certain degree of immunity to electromagnetic interference in a certain environment, that is, electromagnetic sensitivity. EMS also includes electrostatic immunity ESD, radio frequency immunity RS, electrical fast transient burst immunity EFT, surge immunity Surge, voltage sag immunity VoltageDIPandInterrupt, and other related projects
EMI testing projects include:
Radiation emission testing.
Conducted emission test Disturbance power test Current harmonic testingMeasurement of power harmonics Flashing test EMS testing items include:
Electrostatic discharge immunity Radio frequency electromagnetic field immunity Electrical fast transient pulse group immunity Impact (including lightning and surge) immunity Radio frequency field induced conduction immunity Power frequency magnetic field immunity test Voltage drop short interruption and voltage gradual drop immunity
