Electromagnetic Compatibility: Why EFT Testing is Essential for Electronics?
The EFT (Electrical Fast Transient) or burst test is a kind of conducted immunity test that allows you to determine how well electrical or electronic equipment performs when subjected to rapid and frequent voltage spikes and bursts. During the test, the equipment under test (EUT) receives short pulses, which are applied to AC/DC power supply lines or signal/communication lines via a Coupling/Decoupling Network (CDN), control ports, or capacitive clamp. These shape electrical disturbances, known as bursts, following the International IEC 61000-4-4. Electronic devices are constantly exposed to invisible electrical dangers. To ensure devices don't fail or crash, manufacturers usually rely on the crucial process known as EFT Testing . Why is EFT Testing Needed? In the real world, electrical power is rarely smooth. Whenever heavy machinery or motors or even light switches are turned on and off, they create a lot of rapid electrical sparks as well. These disturbances travel through power...
