Concept: An electromagnetic pulse is a transient electromagnetic phenomenon, generally referring to transient high-power electromagnetic radiation generated by electromagnetic weapons, natural lightning, high-power electrical equipment and electrostatic discharge. In terms of time-domain waveform, electromagnetic pulses feature a steep leading edge and narrow pulse width; in the frequency domain, they cover a wide spectrum. When acting on electronic components, electrical equipment or pyrotechnics, they can cause severe interference and damage effects.

Electromagnetic pulse protection devices are mainly designed to address electromagnetic interference issues of military and critical civil facilities under complex electromagnetic environments. They resolve common faults such as power tripping and power loss, damage to precision instruments and equipment, and distortion of observation data caused by electromagnetic pulse interference under high-power, narrow-pulse electromagnetic shock environments. Their core technologies include two functional parts: strong electromagnetic pulse protection & hardening, and electromagnetic environment information security protection.

Electromagnetic pulse protection devices are used to mitigate or eliminate the impacts of weapon-grade electromagnetic pulses on systems within the affected area, improving the electromagnetic survivability of electronic equipment. Meanwhile, they suppress interfering harmonics induced in loop systems (loops formed by power or signal cables) by spatial electromagnetic interference waves generated from strong electromagnetic interference sources. They also comply with the protection requirements for lightning electromagnetic pulses specified in IEC61643-11 standard, and can effectively protect AC power supply systems and equipment power systems from damage caused by transient electromagnetic fields and high-order harmonics.

This electromagnetic pulse protection device is engineered to protect power line systems against strong electromagnetic pulses. It is available in two models: EMP-45 for single-phase power systems and EMP-85 for three-phase power systems.
