Method and systems for suppressing electromagnetic pulse induced surges using combined multiport protection with impedance matching and low insertion loss

A method for suppressing an electrical surge induced by an electromagnetic pulse (“EMP”) generated by a nuclear weapon detonation from reaching a plurality of electronic devices associated with communication channels, said method comprising:

• shunting by a first shunting assembly a first overvoltage exceeding a first E1 predetermined threshold level by an E1 component pulse induced in a signal stream channel connected to a plurality of electronic device ports associated with a network to limit a level of said first overvoltage to a second E1 predetermined threshold level, said shunting occurring within less than one nanosecond after receiving the first overvoltage,
• wherein said first shunting assembly including transient voltage suppressors (TVSs), metal oxide varistors (MOVs), gas discharge tubes (GDTs), other mechanical, electrical and ionization discharge devices (IDDs) and combinations thereof of surge limiting technologies;
• shunting by a second shunting assembly a second overvoltage exceeding a first E2 predetermined threshold level by an E2 component pulse induced in a signal stream channel connected to a plurality of electronic device ports associated with a network to limit a level of said second overvoltage to a second E2 predetermined threshold level,
• wherein said second shunting assembly including transient voltage suppressors (TVSs), metal oxide varistors (MOVs), gas discharge tubes (GDTs}, other mechanical, electrical and ionization discharge devices (IDDs) and combinations thereof of surge limiting technologies;
• and
• shunting by a third shunting assembly a third overvoltage exceeding a first E3 predetermined threshold level by an E3 component pulse induced in a signal stream channel connected to a plurality of electronic device ports associated with a network to limit a level of said third overvoltage to a second predetermined threshold level,
• wherein the said third shunting assembly including transient voltage suppressors (TVSs), metal oxide varisiors (MOVs), gas discharge tubes (GDTs), other mechanical, electrical and ionization discharge devices (IDDs) and combinations thereof of surge limiting technologies.
