电磁兼容性(EMC).第1-3部分:在民用设备和系统上(宇宙射线强度的)高程电磁脉冲EMP(HEMP)效应总则

[中文适用范围]： 本技术报告的目的是描述世界各地实际和模拟电磁脉冲测试中发生的影响。这些影响包括在美国进行的高空核试验期间观察到的影响。 [外文原描述]： The purpose of this Technical Report is to describe the effects that have occurred during actual and simulated electromagnetic pulse testing throughout the world. These effects include those observed during the high-altitude nuclear tests conducted by the United States and the Soviet Union in 1962, and the HEMP simulator tests conducted by many countries during the years after atmospheric testing ended. In addition to direct effects, this technical report also contains information on HEMP coupling to "long lines" as it is important to verify that particular levels of currents and voltages can be induced by HEMP on these lines; this provides a basis for direct injection testing of electronic equipment. It should be noted that, in most cases, the electrical equipment tested or exposed did not contain the sensitive electronics in use today. Also it should be emphasized that all tests and exposures did not produce failure of the equipment; factors such as the geometry of the HEMP interaction and the electromagnetic shielding of the equipment are variables that can produce differing results. The description of these effects is intended to illustrate the seriousness of the possible effects of HEMP on modern electronic systems.
