The NEMP/HEMP power line filter is a combination of linear and nonlinear elements, which are used to mitigate the coupling effects of HEMP. The MIL-STD-188-125-1 lays down the detailed guideline for HEMP filter testing and qualifications. High Voltage High-altitude Electromagnetic Pulse (HEMP) filters are designed to protect sensitive electronics equipment during hazardous transient conditions. These filters are employed to absorb a potentially destructive overshoot voltage. 

​The filters are designed to satisfy the standards of MIL-STD-188-125-1, short pulse and intermediate pulse. Extremely high surge currents up to 100 kA (8/20μs) per line can be diverted. 

This Pulse Current Injection system or PCI is used to measure the performance points of entry according to MIL standards. It is a highly durable system for military use. As a pulse current injection system which will generate a peak current of 1.2kA and approximate source impedance of more than 60 ohms.

These systems are technically used for testing and validation of entire structures which are MIL-STD-188-125-1/2 qualified. Hence the system is compact in nature and portable. Once the pulse current is injected into the establishment or equipment intended for test, one can see what are the outputs achieved within the shielded area and do the self-assessment.

Simulating EMP pulses in a lab or for testing is very essential not only to understand the characteristics of the pulses, but also to understand what steps can be taken to mitigate their effects. E1 Simulator simulates the effect when gamma radiation from the nuclear detonation ionizes atoms in the upper atmosphere. This System produces a very large, but very brief, electromagnetic pulse over the test area of 70 x 70mm.

EMI (Electromagnetic Interference) filters are electronic components designed to suppress electromagnetic noise and prevent it from interfering with sensitive electronic equipment. They work by attenuating unwanted high-frequency noise and harmonics generated by other devices and transmitted through the power line or signal cables.

EMI filters typically consist of passive components such as capacitors, inductors, and resistors, configured in a specific pattern to create a low-pass or band-pass filter. They can be integrated into a variety of electronic devices, including power supplies, inverters, motor drives, and communication systems.

EMI filters are crucial for ensuring reliable operation and compliance with regulatory standards for electromagnetic compatibility (EMC). Without proper filtering, electronic equipment can suffer from performance degradation, malfunctions, or even complete failure.

The feedthrough capacitor is a three-terminal capacitor that is used to reduce high frequencies. The feedthrough capacitor, unlike regular three-terminal capacitors, is directly installed on the metal panel, resulting in a lower grounding inductance and a negligible effect on the lead inductance. As a result, the feedthrough capacitor provides good filtering. The better the electromagnetic interference suppression effect, especially for high-frequency electronic equipment, the better.
