There is a bunch of good videos somewhat down on this page.

Let me slide this on in...Kathy Loves Physics, on Faraday cages

Page 42: "Probably one of the most famous and severe effects from solar storms occurred on March 13, 1989. On this day, several major impacts occurred to
the power grids in North America and the United Kingdom. This included the complete blackout of the Hydro-Quebec power system and damage to two
400/275 kV autotransformers in southern England. In addition, at the Salem nuclear power plant in New Jersey, a 1200 MVA, 500 kV transformer was damaged
beyond repair when portions of its structure failed due to thermal stress. The failure was caused by stray magnetic flux impinging on the transformer core.
Fortunately, a replacement transformer was readily available; otherwise the plant would have been down for a year, which is the normal delivery time for
larger power transformers. The two autotransformers in southern England were also damaged from stray flux that produced hot spots, which caused
significant gassing from the breakdown of the insulating oil."

Page 45: "It is not practical to try to protect the entire electrical power system or even all high value components from damage by an EMP event. There are
too many components of too many different types, manufactures, ages, and designs. The cost and time would be prohibitive. Widespread collapse of the
electrical power system in the area affected by EMP is virtually inevitable after a broad geographic EMP attack ..." 

Page 88: "The electronic technologies that are the foundation of the financial infrastructure are potentially vulnerable to EMP. These systems also are 
potentially vulnerable to EMP indirectly through other critical infrastructures, such as the power grid and telecommunications." 

Page 110: "Similar electronics technologies are used in both road and rail signal controllers. Based on this similarity and previous test experience with these 
types of electronics, we expect malfunction of both block and local railroad signal controllers, with latching upset beginning at EMP field strengths of 
approximately 1 kV/m and permanent damage occurring in the 10 to 15 kV/m range." 

Page 112: "Existing data for computer networks show that effects begin at field levels in the 4 to 8 kV/m range, and damage starts in the 8 to 16 kV/m range. 
For locomotive applications, the effects thresholds are expected to be somewhat higher because of the large metal locomotive mass and use of shielded 
cables." 

Page 115: "We tested a sample of 37 cars in an EMP simulation laboratory, with automobile vintages ranging from 1986 through 2002. ... The most serious 
effect observed on running automobiles was that the motors in three cars stopped at field strengths of approximately 30 kV/m or above. In an actual EMP 
exposure, these vehicles would glide to a stop and require the driver to restart them. Electronics in the dashboard of one automobile were damaged and 
required repair. ... Based on these test results, we expect few automobile effects at EMP field levels below 25 kV/m. Approximately 10 percent or more of the 
automobiles exposed to higher field levels may experience serious EMP effects, including engine stall, that require driver intervention to correct." 

Page 116: "Five of the 18 trucks tested did not exhibit any anomalous response up to field strengths of approximately 50 kV/m. Based on these test results, we 
expect few truck effects at EMP field levels below approximately 12 kV/m. At higher field levels, 70 percent or more of the trucks on the road will manifest 
some anomalous response following EMP exposure. Approximately 15 percent or more of the trucks will experience engine stall, sometimes with permanent 
damage that the driver cannot correct." 

Page 153: "Results indicate that some computer failures can be expected at relatively low EMP field levels of 3 to 6 kilovolts per meter (kV/m). At higher field 
levels, additional failures are likely in computers, routers, network switches, and keyboards embedded in the computer-aided dispatch, public safety radio, 
and mobile data communications equipment. ... none of the radios showed any damage with EMP fields up to 50 kV/m. While many of the operating radios 
experienced latching upsets at 50 kV/m field levels, these were correctable by turning power off and then on."
