High-altitude Electro-Magnetic Pulses (HEMP) generated from both natural and intentional sources can cause disturbance and damage to ground based electrical systems, aircraft, and vehicles.
A solar flare, nuclear explosion, lightning strike and such events can cause a major blast of electromagnetic energy that spreads out in all directions.
HEMP filters are designed to protect specific electrical assemblies, or sub-assemblies from HEMP Pulses. The EMP/HEMP filters protect electronics equipment by absorbing the potentially destructive EMP voltage and current within the filter before it reaches the electronic devices.
230 VAC for Single Phase,
440 VAC for three Phase
HEMP protection methods are according to the following MIL specifications:
HEMP power line filters are designed to withstand all the E1, E2 and E3 pulse types. These components are subjected to the PCI test and must match the shielding effectiveness as stated in MIL-STD-188-125.
