A filter design configured to operate in the medium voltage range of 1000 to 5000 volts, provides protection against Electromagnetic Pulse/High Altitude Electromagnetic Pulse (EMP/HEMP) intentional electromagnetic interference pulses. The filter utilizes no oil filled components to preclude the catastrophic failures (explosions) during operation. Many of the components incorporated in the present design are suited to absorbing harmonics without failing. In addition to mitigating E1 and E2 pulses, the filter is resistant to line harmonics which have proved to cause filter failure in past designs. The filter provides EMP/HEMP conducted pulse protection for downstream electronics inside hardened shelters for medium and high voltage applications.
