Electrical Fast Transient (EFT) Testing

Electrical Fast Transient/Burst (EFT/B) refers to transient bursts generated by various electrical appliances (or equipment) within the same power supply circuit during operation (such as switches, relays, etc.). If inductive loads are repeatedly switched, the burst pulses will occur multiple times at corresponding intervals. These pulses feature short rise times, high repetition rates, low energy, and a wide spectral distribution. EFT/B interference can cause performance degradation or malfunction of electrical appliances (or equipment).
