EMPShield - I suspect this is complete bullshit but why is it bullshit?
网页The only thing that appears to be special about the EMPShield is the low VPR (Voltage protection rating) which is good. VPR is the voltage level at which the surge protector starts to work so lower the better. So now in the market for a whole house Surge protector but most are significantly cheaper then the EMP shield.
EMPShield. Is it bullcrap? : r/preppers - Reddit
网页2020年2月12日 · A lot of folks are getting burned, even some people in industry who should know better. EMP shield is perhaps the biggest consumer electrical joke out there besides EcoChamp or EcoWatt. Their "military EMP testing results" are completely bogus and a lie. Sure, they were tested, but you have to read into the details.
Emp shield? : r/ElectricalEngineering - Reddit
网页2023年9月7日 · The only way I know of to protect from emps is to use a faraday cage which this clearly isn't. It claims to shunt 280,000 amps and activate in one nanosecond, those are just numbers they pulled out of their ass. This isn't going to protect your house from lightning and your car is already pretty safe.
Anyone using an EMP shield on their car? : r/preppers - Reddit
网页2023年8月17日 · The point is actually to insulate things like the car radio against the vehicle's own extreme EM emissions, but the shielding goes both ways. If your car has a tape deck, you don't have enough exposed electronics to worry. In most cases the body will act as a faraday cage. 1.
First time seeing the infamous EMP Shield device, and I’m ... - Reddit
网页2023年7月18日 · A "backpack portable" EMP generator such as the commercially produced Montena PPG-E1-1200 (carryon sized) when triggered at ground level throws a destructive EMP wave to a radius of only about 15 meters at max output; as such, even with no actual hardening or shielding, sensitive electronics can be reasonably secure from such devices …
[LONG POST] Understanding EMPs and how to prepare : …
网页2022年3月30日 · This is the basis of how a generator works. An EMP is basically a very strong magnetic field that can induce very large current/voltage into electrical conductors – especially long wires. One of the ways to measure the size of an EMP is to determine how much electricity (measured in volts) is induced into a conductor per meter.
Whats is yalls opinions on the EMP shield you can install on
网页2020年9月7日 · Short answer; you cannot completely shield a car unless it is parked inside a faraday cage. Anything proclaiming to do such a thing is likely snake oil. Long answer; an EMP would fry ANY electronics with microprocessors; that means cars after 1980/90 (ish) are pretty much toast unless you can install the spare components after the event.
Deer whistle? No. Rodent repellent? No. Emp Shield? absolutely
网页2022年10月13日 · Jeez, they're $400! It looks like it's just a surge protector: EMP Shield will protect all the electronics and equipment connected to your electrical system. This is accomplished by shunting (shorting) the over voltage coming in from the grid and the induced voltage that is collected within your home.
EMP Shield opened : r/Justrolledintotheshop - Reddit
网页2023年3月31日 · ADMIN MOD. EMP Shield opened. I probably could have done a better job with different tools but I used a cut off tool/wheel to open this thing up. As far as I can tell it has a plastic housing with a metal plate attached on the top with two rivets and what looks like a foam gasket. As I was cutting, I thought it was solid plastic but the center ...
