How Does EMP Shield Work? 
The EMP Shield can see and 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 voltage surges that are collected within your home. Whether the electrons are collected within your home or are attempting to come into your electrical system from outside the home (the grid), the EMP Shield will see the surge and protect your electrical system. The EMP Shield reacts in less than 1 billionth of a second. Since the shunting is completed incredibly fast, the over voltage is drained away from the equipment before the voltage can rise high enough to damage any equipment. We call this new technology SightSpeedTM.

What is EMP Shield? 
EMP ShieldTM is the worlds only tested and approved EMP protection technology for an entire electrical system. 
The EMP Shield is a very robust electrical surge arrestor, designed to exceed the requirements of MIL- STD-188-125-1 for shunting over-voltage spikes (conductor to conductor, conductor to ground, conductor to neutral, and ground to neutral) very quickly. Built to exceed military standards, EMP Shield is also one of the worlds fastest whole home surge protectors operating in less than 1 billionth of a second. 

EMP Shield is designed to protect an entire home from Lightning, CME (coronal mass ejection, power surges, and an EMP (electromagnetic pulse). Proven and tested at Keystone Compliance, a Federally approved Department of Defense (DOD) testing facility, Our EMP Shield was struck with over 40x EMP strikes with no impact to the device. 

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 Tests Has EMP Shield Completed? 
EMP Shield is a family of incredibly robust EMP, solar flare, and lightning defense technologies. 
They have been designed to exceed the US Military requirements for protection against a high-altitude nuclear detonation that results in an electromagnetic pulse. This family of products has been tested at Keystone Compliance, a DOD Certified 
Testing Laboratory, to verify compliance with the following Military Standards: 

MIL-STD-188-125-1 - High Altitude EMP
MIL-STD-461G - Control of Electromagnetic Interference 
MIL-STD-461-CS-115 - The purpose of CS115 is to test an electronic or electrical system to withstand signals coupled onto the test unit’s associated cabling. The test unit will be subjected to rise and fall times, pulse width, and amplitude as specified on Figure CS115-1 at a 30 Hz rate for one minute.
MIL-STD-461-CS116 applies to 10 kHz to 100 MHz for all interconnecting cables, including power cables, and individual high 
side power leads
MIL-STD-461-CS117 - apples to all safety-critical equipment interconnecting cables and non-safety critical equipment with interconnecting cables/electrical interfaces that are part of or connected to equipment performing safety critical functions. 
The goal is to ensure a test unit’s ability to withstand lightning transients coupled onto the test unit’s associated cables and power leads. 
MIL-STD-461-RS105 - Transient electromagnetic pulse of up to 50 kV/m, double exponential wave with a rise time in the nanosecond range, that is applied to the equipment under test (EUT) at least 5 times and 
MIL-STD-464C - Electromagnetic Environmental Effects Requirements for Systems. 
Our test results show that we begin shunting the overvoltage condition in less than 1 nanosecond, and our units are designed to shunt over 100,000 Amps per phase. Our devices are scalable to any size.
