Transients are brief but dramatic electrical disturbances that can cause electrical interference. When a transient is transferred along a cable, it is referred to as conducted. Thus, conducted immunity testing checks for susceptibility within electrical components contained in household appliances, vehicles, or aircraft to prevent serious malfunctions.
Conducted immunity consists of several similar but distinct tests. Since transients can occur from an indirect lightning strike, electrostatic discharge (ESD), or electrical switching between devices on the same grid, a different test is required to simulate each type. ATEC rents equipment which can perform multiple types of tests to ensure all components are up to the various standards outlined by the IEC and others.
Below is our diagram of a common conducted immunity test setup.
Conducted Immunity Standards
The following standards are some of the most common that our rental customers need to fulfill.
Typically the first step of the testing process, ESD tests most commonly adhere to IEC 61000-4-2
and utilize an ESD gun
to verify waveforms. This is followed by IEC 61000-4-4
and IEC 61000-4-5
, the electrical fast transient (EFT) and surge portions of testing respectively. For these, an EFT generator
, coupling clamps, and oscilloscopes are needed.
ATEC offers conducted immunity testing bundles that include all necessary equipment based on the type of standard to be met. Contact us
