An EFT generator is an electrical fast transient (EFT) test system that simulates EFT as part of
conducted immunity testing. An EFT is an electrical transient, or disturbance, caused by a spark in the air or another gaseous discharge. Commonly, the opening of a switch through which current is flowing triggers the transient; arcing occurs between the contacts as the switch is opened. The resulting electrical surge is referred to as an EFT and sometimes as a burst, due to its sudden, violent nature.
What is an EFT Generator?
A transient generator with electrical fast transient and burst capabilities will operate with a short rise time and high rate of repetition and generate relatively low energy transients, with the intention of emulating the switching of inductive loads. The switching of inductive loads in the field can be the toggling of an electric switch, a motor and relay system, or adjacent bundles of cables. Initially, while the contacts remain close together, arcing commences at a low voltage and high frequency, and afterwards at a high voltage and low frequency as the contacts separate.
ATEC offers affordable EFT generator rental rates for products from leading EMC manufacturers like
Haefely,
EMC Partner,
Teseq, and more. Our electrical fast transient/burst immunity test systems are often multifunction, meeting
IEC 61000-4-4,
IEC 61000-4-5, and
IEC 61000-4-11 standards, as well as ANSI C62.41 and
ANSI C62.45. ATEC will equip you with a complete conducted immunity test system that includes a transient generator, power line CDNs, coupling clamps, and oscilloscopes for verification.
