Why wouldn't a fuse protect from emp-like damage?
My understanding is that an emp introduces electrical currents in the lines. Protecting the transformer from electrical overloads should protect it from emp. No?
- Xamayon 5y agoThe damage may happen too quickly, similar to how typical fuses or circuit breakers won't protect you from a power surge or nearby lightning strike. Other tech would probably work though. Unfortunately, there's a lot of conflicting info on how powerful HEMP attacks, CMEs, etc would be/how much protection would be needed to have any effect at all. Having reliable info would greatly help for determining the feasibility of protecting systems all over the world. Regardless of 'criticality' even, as what good would the internet be if HN's servers and such are all down? ;)
- Animats 5y agoAn EMP attack and a geomagnetic disturbance are completely different. EMP events have rise times around 10ns. Geomagnetic disturbances have rise times in minutes.
- jhayward 5y agoGeomagnetic storms are not EMPs. An EMP is a high-frequency, very intense burst in the electric field. A geomagnetic storm is a low-frequency, low-intensity change in the magnetic field. The effects of EMPs vs geomagnetics are very different.
