Power System Restoration Following a High-Altitude Electromagnetic Pulse–Induced Blackout
Triggered by the high-altitude detonation of a nuclear weapon, a high-altitude electromagnetic pulse (HEMP) is a sudden burst of electromagnetic radiation that can damage electronic components in the power grid. This report discusses global principles and practices for power system restoration plans following a widespread blackout and examines how a HEMP event could impact these […]

Coupling of Early-Time High-Altitude Electromagnetic Pulse (E1) into Technological Infrastructure
Triggered by the high-altitude detonation of a nuclear weapon, a high-altitude electromagnetic pulse (HEMP) is a sudden burst of electromagnetic radiation that can damage electronic components in the power grid. One component of HEMP is a high-amplitude electric field pulse or E1. This study examines the characteristics of E1 and describes methods to assess potential […]
