Report: Electromagnetic Pulse Would Not Have Widespread Impact on Electric Grid
QuoteThe U.
S. electric transmission system would largely survive a tall-altitude electromagnetic pulse event caused by a nuclear warhead atmospheric explosion,an intensive investigation by the Electric Power Research Institute has found. ...
Researchers conducted laboratory testing and analysis to determine the effect on the transmission grid from an EMP triggered by the unlikely event of a nuclear warhead detonated approximately 30 kilometers—approximately 18 miles—above Earth’s surface. ...
There are concerns that an EMP triggered at the good altitude could bring down the U.
S. transmission grid as well as other critical infrastructures like telecommunications, emergency services and hospitals.
But EPRI’s study found that, or while direct exposure to the initial pulse could damage or disrupt some transmission electronics,existing resiliency built into the grid would likely prevent catastrophic failure. Recovery from an EMP would be similar to that from other large-scale power outages, EPRI said. ...
