    27、of the consequences of a high-altitude nuclear explosion. Those dealing with this subject consider two cases: - high-altitude nuclear explosions; - low-altitude nuclear explosions. For civil systems the most important case is the high-altitude nuclear explosion. In this case, the other effects of th

    28、e nuclear explosion: blast, ground shock, thermal and nuclear ionizing radiation are not present at the ground level. However, the electromagnetic pulse associated with the explosion may cause disruption of, and damage to, communication, electronic and electric power systems thereby upsetting the st

    29、ability of modern society. The object of this standard is to establish a common reference for the conducted HEMP environment in order to select realistic stresses to apply to victim equipment for evaluating their performance. 2 Normative references The following normative documents contain provision

    30、s which, through reference in this text, constitute provisions of this part of IEC 61000. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of IEC 61000 are encouraged to investigate the possibility of a

    31、pplying the most recent editions of the normative documents indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards.

    33、for HEMP conducted disturbance - Basic EMC publication 3 General A high-altitude (above 30 km) nuclear burst produces three types of electromagnetic pulses which are observed on the earths surface: - early-time HEMP (fast); - intermediate-time HEMP (med iu m) ; - late-time HEMP (slow). Historically

    34、most interest has been focused on the early-time HEMP which was previously referred to as simply HEMP. Here we will use the term high-altitude EMP or HEMP to include all three types. The term NEMP covers many categories of nuclear EMPs including those produced by surface bursts (SREMP) 2, or created

    35、 on space systems (SGEMP) 3). Because the HEMP is produced by a high-altitude detonation, we do not observe other nuclear weapon environments such as gamma rays, heat and shock waves at the earths surface. HEMP was reported from high-altitude nuclear tests in the South Pacific by the US and over the

    36、 USSR during the early 1960s, producing effects on electronic equipment far from the burst location. This standard presents the conducted HEMP environment induced on metallic lines, such as cables or power lines, external and internal to installations, and external antennas. i) NEMP: Nuclear electro
