1 Scope

This part of GB /Z 30556 defines the concept of protection of electromagnetic pulses generated by high-altitude nuclear explosion (hereinafter referred to as HEMP) and gives

Related information.

The purpose of this section is to provide some groundwork for the following areas.

--- Civil Facilities HEMP adequate protection design;

--- The existing protection against the HEMP strength assessment;

--- Comparison of HEMP protection and lightning protection requirements, the purpose is to show whether they can low-cost combination;

--- Emphasized the difference between HEMP protection and lightning protection requirements, the purpose is to assess when there is no additional lightning protection

Protective measures HEMP results.
