In January 2021, the United States Department of Energy (DOE) released a memorandum detailing recommended E1, E2, E3A and E3B waveforms and electric field (E-field) levels for use in the assessment of electrical systems within critical infrastructure industries (CII).
An EMP Attack on the U.S. Power Grids and Critical National ...
Mar 20, 2025 · A few seconds later, the following EMP E3B Heave Waves destroy most of the Extra High Voltage (EHV) Circuit Breakers and at least 1/3 of the Large Power Transformers (LPTs) that are required for the long-distance transmission of 90% of the electricity in the U.S. The damage and destruction of the EHV Circuit Breakers and LPTs will leave entire ...

Aug 23, 2019 · conclusions of the EPRI report, effective high-altitude EMP protections will not be implemented, jeopardizing security of the US electric grid and other interdependent infrastructures. Participants in the Electromagnetic Defense Task Force 2.0 (EDTF 2.0) 1 commend the work of
HEMP E3A and E3B •The E3 is usually broken into two components –the E3A “Blast Wave” (seconds) caused by the expansion of the nuclear fireball, expelling the Earth’s magnetic field –the E3B “Heave” as bomb debris and air ions follow geomagnetic lines …

the E3 signal from hot plasma magnetic bubbles as being part of E3B and not E3A. This report focuses on E3B for burst-altitudes from 90 to 250 km. We will provide a set of unclassified E3B waveforms and demonstrate their dependence on yield, burst -altitude, and burst - latitude.
Participants in the Electromagnetic Defense Task Force 2.0 (EDTF 2.0)1 commend the work of EPRI and its supporting utilities for the testing of digital protective relays (DPRs) against ultrafast E1 high altitude electromagnetic pulses (HEMP).
Sixty Years After, Physicists Model Electromagnetic Pulse of a Once ...
The E3 portion of the EMP, it turns out, exhibits two types of behavior, dubbed E3a and E3b. E3a travels around the x-ray ionization patch to reach the Earth’s surface, a longer bypass that diminishes the pulse’s intensity. E3b moves straight through the patch, striking the planet directly.
EMP Waveforms Based on Published Research - PowerWorld
EMP Waveforms Based on Published Research. The newest builds of PowerWorld Simulator with the GIC add-on no longer contain a function to calculate time-varying series voltage inputs for EMP E3A and E3B time and spatial functions based on Oak Ridge National Laboratory (ORNL) research [1] and International Electrotechnical Commission (IEC) standards.
