IEC 61000-4-4 6kV Intelligent Electrical Fast Transient Generator (EFT)
Standards & Clauses:
IEC 61000-4-4/ GB/T17626.4: Electrical fast transient immunity test
Samples and Restrictions:
Industrial controllers, home appliances, medical electronics, communication electronics, components, automation controllers, etc.
Intended to demonstrate the immunity of electrical and electronic equipment when subjected to types of transient disturbances such as those originating from switching transients (interruption of inductive loads, relay contact bounce, etc.)
Burst immunity test is the interference generated by many mechanical switches in the simulation grid when switching inductive load. These types of disturbances are characterized by narrow clusters of pulses with high pulse repetition rates (kHz-MHz), steep rising edges (ns), short durations of individual pulses (10-100 ns) with amplitudes up to kV level. Narrow pulses in clusters can charge the junction capacitance of the semiconductor device, which can cause a line or device error when energy accumulates to a certain degree. During the test, a pulse is superimposed on the power supply line (via the coupling / decoupling network) and the communication line (via the capacitive coupling clip) to interfere with the device. The experimental part of the EUT mainly includes the power supply port, PE, signal and control port of the equipment.
