EMP, Lightning, and Power Transients: Their Threat and Relevance to EMP Protection Standards for Telecommunication Facilities.
Abstract
The electromagnetic pulse (EMP) is a phenomena created by nuclear explosions. It is a transient electromagnetic wave produced by exoatmospheric, atmospheric, and surface bursts and is characterized chiefly by its short duration, high intensity field. This electromagnetic field can cause severe disruption and possible damage to communications equipment. The most serious EMP threat is that from an exoatmospheric or high altitude burst which potentially can illuminate a large fraction of a communications network and simultaneously disrupt or damage communication equipment over a wide geographical user service area. It is EMP from the high altitude burst that is emphasized in this document since the EMP, blast, radiation, and thermal effects of atmospheric and surface bursts are only significant in negating geographically small communication functions. Lightning and Power line energy surges are discussed. The published surge characteristics for the time domain are provided and the energy threat defined for equipment connected to cable conductor interfaces.
