What is EMP?

EMP (Electromagnetic Pulse) is an intense burst of electromagnetic (EM) energy caused by an abrupt, rapid acceleration of charged particles.

EMP Effects: A widespread collapse of the electric power grid could lead to cascading effects on our interdependent infrastructures, possibly lasting weeks or months.

“Should the electrical power system be lost for any substantial period of time … the consequences are likely to be catastrophic … machines will stop; transportation and communication will be severely restricted; heating, cooling and lighting will cease; food and water supplies will be interrupted; and many people may die.”  — 2008 EMP Commission

What is HEMP?

Greatly simplified, HEMP refers to a potential nuclear explosion detonated high above our planet’s surface. The higher the altitude, the greater the area potentially impacted on earth. HEMP measurements focus on three pulses: E1 in nanoseconds, E2 in microseconds (similar to lightning), and E3—a longer phase potentially lasting minutes on grid systems, similar to a solar flare.

A high-altitude electro-magnetic pulse (HEMP) – is capable of influencing the very magnetic field of the Earth. This man-made event is unleashed by detonating a nuclear payload a few hundred kilometers above and oriented towards the Earth’s surface. A HEMP event creates three distinct event signatures that together have the potential to wreak havoc on modern electrical systems, large and small.

The range and extent of damage this type of destructive event would cause to commercial networks including utilities, 911 responders and transportation hubs is being evaluate globally by government leaders, military agencies, and scientists. As experts in highly specialized EMP/HEMP filter technology, top defense contractors have relied on Transtector’s design experience and patented technology to meet the requirements set by military standards for EMP-EMI mitigation. This proven technology and tested product mix is now being expanded to support commercial network operators as they plan HEMP network threat assessments.

Learn about the four pillars of protection you can implement to guard a system against HEMP and EMP: surge protection, grounding, shielding, and filtering. And listen in for an extra bonus pillar: backup power.

In this Spirit: Behind the Screen podcast, Dan Rebeck and Adam Perone of Transtector and PolyPhaser discuss HEMP protections

Whether you’re concerned about facilities, high-reliability military equipment, or your local community networks, electromagnetic pulse (EMP) could disrupt your day-to-day capabilities. From leaving you without power to leaving you without data or sensitive equipment, having a plan to address EMP now protects you from equipment loss in the future.

Add in high-altitude electromagnetic pulse (HEMP), which can generate 3 separate strong EMP events, and our vulnerability becomes much more complicated.
