|| Electromagnetic compatibility (EMC) - Part 2: Environment - Section 9: Description of HEMP environment - Radiated disturbance. Basic EMC publication
||This section of IEC 61000-2 defines the high-altitude
electromagnetic pulse (HEMP) environment that is one 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 the 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 stability of modern
The object of this standard is to establish a common reference for
the HEMP environment in order to select realistic stresses to apply
to victim equipment for evaluating their performance.
