Tag Archives: High-altitude electromagnetic pulse (HEMP)
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 […]
Researchers subjected 46 power system protection relays to the E1 component of a high-altitude electromagnetic pulse to determine what they can withstand before damage occurs.
Magnetohydrodynamic Electromagnetic Pulse Assessment of the Continental U.S. Electric Grid: Geomagnetically Induced Current and Transformer Thermal Analysis
The high-altitude detonation of a nuclear weapon can generate a large electromagnetic pulse—a sudden burst of electromagnetic radiation. This modeling study assessed the impacts of such a burst on bulk-power transformers.
