BS EN 61000-2-10:1999

What is BS EN 61000-2-10 - HEMP environment about? 

BS EN 61000-2-10 is an international standard that focuses on electromagnetic compatibility (EMC) of the HEMP environment. 

BS EN 61000-2-10 defines the high-altitude electromagnetic pulse (HEMP) conducted environment that is one of the consequences of a high-altitude nuclear explosion.  

BS EN 61000-2-10 presents the conducted HEMP environment, induced on metallic lines, such as cables or power lines, external and internal to the installations, and external antennas. 

Those dealing with this subject consider two cases: 

• High-altitude nuclear explosions 
• Low-altitude nuclear explosions 

BS EN 61000-2-10 covers general information relevant to the HEMP environment that includes related terms and definitions, description of HEMP environment, conducted parameters, early-time HEMP external conducted environment, intermediate-time HEMP external conducted environment, late-time HEMP external conducted environment, HEMP internal conducted environment, etc.     

Who is BS EN 61000-2-10 - HEMP environment for?  

BS EN 61000-2-10 on the description of the HEMP environment for electromagnetic compatibility (EMC) is relevant to: 

• Manufacturers of testing equipment 
• Installers of testing equipment 
• EMC testing authorities 
• Electrical engineers 
• Electricians 
• Electromagnetic engineers 

Why should you use BS EN 61000-2-10 - HEMP environment? 

The electromagnetic field generated by a high-altitude nuclear explosion can induce currents and voltages in all metallic structures. These currents and voltages propagating in conductors represent the conducted environment. This means that the conducted environment is a secondary phenomenon, a consequence of the radiated field alone. All metallic structures (i.e., wires, conductors, pipes, ducts, etc.) will be affected by the HEMP.  

BS EN 61000-2-10 assists the user with the description, classification, and compatibility levels of the high-altitude electromagnetic pulse (HEMP) environment. It establishes a common reference for the conducted HEMP environment to select realistic stresses to apply to victim equipment for evaluating their performance.  

BS EN 61000-2-10 lays down the external conducted common-mode environments, calculated using simplified conductor geometries. It specifies HEMP environments for the early, intermediate, and late-time waveforms. These conducted external environments help users evaluate the performance of protection devices outside of a building. 

Overall, BS EN 61000-2-10 describes the conducted environment, which is important for the users, as it can direct the HEMP energy to sensitive electronics through signal, power, and grounding connections.
