What is an EMP Shield?

The EMP Shield is a very robust electrical surge arrester, designed to exceed the requirements of MIL-STD-188-125-1 used by the Department of Defense for devices shunting over-voltage spikes to ground and neutral very quickly. 

MIL-STD-188-125-1 requires that the over-voltage spike from the E1 spike begin shunting 5,000 Amps within 20 nanoseconds. All EMP Shield models start shunting over-voltage in less than 10 nanoseconds, while some models are able to begin shunting over-voltage in less than 1 nanosecond. The EMP Shields are also designed to continue protecting through the expected durations of the E2 and E3 spikes produced in a HEMP strike.

What is an EMP?

A nuclear EMP is defined as having 3 distinct pulses of voltage/current. The E1 pulse is caused by the gamma rays released during the nuclear reaction. The Gamma rays interact with the electrons and the nucleus of the atoms that make up the atmosphere, and this interaction results in freeing electrons from their atoms. The free electrons ionize the atmosphere (ionization results in electron flow), which can be seen as the flow of electricity through anything that acts as an antenna. All of the wires that make up our nations’ electrical grid make an excellent antenna, which will produce an over-voltage condition throughout the affected area. For an optimally positioned detonation (approximately 300 miles high and over the center of the US), the entire nation will be affected by the E1 pulse. The E1 pulse starts at the time of the detonation of the weapon and continues until 1 microsecond after the detonation.

The E-2 pulse starts at 1 microsecond and continues until approximately 1 second after the detonation. The E-2 pulse is caused by the inelastic scattering (matter bouncing off of other matter) of the matter from the nuclear weapon interacting with the matter that makes up the atmosphere continuing to ionize the atmosphere.

The E-3 pulse starts at approximately 1 second after the detonation and can continue for several minutes. The E-3 pulse is caused by the nuclear detonation distorting the earth’s geomagnetic structure, and then its reconfiguration. As the magnetic lines are pushed out of configuration and then come back into normal configuration, electricity is generated, and flows through the atmosphere until it contacts an antenna (wires).

The antenna that is most affected will be the nations power grid, but all arrays of wiring (even in your house) will act as large or small antennas, and will produce the flow of electricity and over-voltage conditions.

Does this EMP Shield device work in every country?

Yes, it does – but for people ordering outside the USA they need to email us or put a comment in their order as in what country they are planning to use the device. If the unit for their voltages is not in stock we can have one ready to ship in 48-72 hours

Will the EMP Shield work on solar power systems?

Yes, however, we will need the operating voltage of your system (like 12v, 24v or 48v). Send us an email or put a comment in your order as to what voltage your system uses for the panels. If the unit for your voltage is not in stock we can have one ready to ship in 48-72 hours.

Is the EMP Shield hard to install?

No – We recommend you have it installed by a licensed electrician and/or used in accordance with electrical codes and regulations. However, it is very simple to install. 

Is the EMP Shield attached to my homes breaker box?

We have ways for you to mount the EMP Shield box (6″ wide x 2.5″ tall x 3.0″ deep) on the wall beside your breaker box, inside the breaker box and inside the breaker box with a small LED box just outside the edge of the breaker box so you can see the status of all the lines.

Can we use the EMP Shield on our boats, vehicles, or aircraft?

Yes you can. You need to email us or put a comment in your order telling what brand, model and operating voltage your boat or aircraft uses.
