IEC 61000-2-9: 2025 defines the high-altitude electromagnetic pulse (HEMP) environment that is one of the consequences of a high-altitude nuclear explosion. There are two cases of nuclear detonations: - 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…
