HEMP Tested Protection Devices

HEMP Tested Protection Devices

Transtector Systems today released a comprehensive line of surge protection devices engineered and tested to address the growing threat of electromagnetic pulse (EMP), specifically high-altitude EMP (HEMP), in all types of communications networks. HEMP Tested protection devices from Transtector meet the highest military standards and guidelines from the Department of Homeland Security (DHS) and the Alliance for Telecommunications Industry Solutions (ATIS).

By meeting peak threat levels of Military Standard MIL-STD-188-125, Transtector HEMP Tested surge protection devices are optimized for high-level protection in AC, DC and data network applications. Innovative and patented Transtector silicon avalanche diode technology ensures long-term non-degrading high performance.

What is HEMP?
Broadly defined, HEMP refers to an Electro-magnetic reaction created by a nuclear explosion detonated high above the planet’s surface. The ensuing electromagnetic pulse would have the potential to wreak havoc on communications networks. Growing nuclear threats around the globe push the potential HEMP risk ever higher.

For product testing and reliability purposes, 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). For E4-level EMP solutions, Transtector partner brand PolyPhaser provides HEMP Tested RF solutions.
