34、troduction The IEC has initiated the preparation of standardized methods to protect civilian society from the effects of high altitude nuclear bursts. Such effects could disrupt systems for communications, electric power, information technology, etc. This section of IEC 1000-5 is part of a complete

35、set of standards that covers the entire category of immunity to high altitude nuclear electromagnetic pulse. The appropriate acronym is either HA-NEMP or more simply HEMP. The application of this section is, however, not dependent on access to other sections and parts of the IEC 1000, except for tho

36、se specifically referred to. IEC/DIS 1000-4-24 1)indicates the projects running in parallel with this work. 1 Scope This part of IEC 1000-5 defines how protective devices for conducted disturbance proposed for HEMP protection shall be specified. It is intended to be used for the harmonization of exi

37、sting or future specifications issued by protective device manufacturers, electronic equipment manufacturers, administrations and other ultimate buyers. Performance requirements shall be given in future IEC documents. This section covers protective devices currently being used for protection against

38、 induced HEMP transients on signal and low voltage power lines (nominal voltage up to 1 kV a.c.). General information can be applied also to high voltage lines. However, in these cases, the additional requirements for the protection levels of existing lightning arresters (especially gapless MO-arres

39、ters) are under consideration. In general, HEMP-relevant parameters, i.e.parameters related to very fast changes of electromagnetic field, voltage (u) and current (i) as a function of time, are of interest. For basic specifications, reference is made to other relevant standards (see annex E) dealing

40、 with phenomena other than HEMP. When such standards do not adequately consider the requirements of modern electronics, additional specifications, modifications or extensions based on non-HEMP-relevant standards are defined. 2 Normative references The following standards contain provisions which, th
