Abstract:At the instant of switching electrical and electronic equipment (such as switch and circuit breaker), a transient disturbance
will be produced. This pulse is easy to couple to the equipment and will affect the normal work. So it is necessary to examine
the anti-interference performance of the sensitive equipment by electrical fast transient/burst immunity test with high repetition
frequency. Particularly, it is necessary to examine the active medical devices. In this study, we compared the domestic and foreign
standards. The formation theory of electrical fast transient/burst was analyzed, and the influence of two different repetition
frequencies was analyzed. Through the classification test of active medical devices, the effect of two repetition frequencies on the
tested equipment (EUT) was tested. The test data and rectification measures were given. In the test, we should consider multifactor
and choose repetition frequency, to meet the electromagnetic compatibility test.
