Transient Generators

Transient generators simulate transients for conducted immunity EMC testing. ATEC has a variety of transient generator test systems available to rent with industry-leading rates. Whether you need a generator for one specific test or one that can do them all, we can help out. Our manufacturers include Haefely, EMC Partner, Teseq, and more.

To test a device’s immunity to transients, test engineers use transient generators, also known as transient immunity test systems, to reproduce transients in a controlled environment. Waveform variation allows for a transient generator to replicate nearly any transient a device could be exposed to, and most testers will include modules for specific waveforms (i.e. surge, EFT, ring wave, etc.).

Generators designed for EMC tests on commercial, industrial, medical, and IT devices comply with the following test standards in the waveforms they generate.
 

Commercial Transient Generator Test Standards

• IEC 61000-4-4 | Electrical fast transient & burst
• IEC 61000-4-5 | Surge wave, combination wave, and telecom wave
• IEC 61000-4-8 | RF magnetic field
• IEC 61000-4-9 | Pulse magnetic field
• IEC 61000-4-10 | Damped oscillatory magnetic field
• IEC 61000-4-11 | Voltage dips & interrupts
• IEC 61000-4-12 | Ring wave (damped oscillatory non-repeating)
• IEC 61000-4-18 | Damped oscillatory wave (DOW)
• IEC 61000-4-29 | DC power voltage dips & interrupts
• ANSI/IEEE C37.90.1 | Surge withstand capability for electric power relays/relay systems
• ANSI/IEEE C62.41 | Surge voltages in low-voltage AC circuits

Although the tests are similar in nature, the automotive and military/aerospace industries require different equipment and operate under different standards. Visit our pages on automotive transient generators and military & aerospace transient generators to learn more about these requirements.
