Electromagnetic compatibility installation and mitigation guidelines
High altitude nuclear electromagnetic pulse (HEMP) protection concept
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.
