Abstract
Disclosed are methods and systems for suppressing extreme voltage surges due to transient electromagnetic energy disturbance such as a detonation of a nuclear weapon at high altitude generating an EMP (HEMP) comprising E1, E2, and E3 component pulses. Surge protection assemblies form a surge protection device (SPD) mounted directly on AC and DC power line conductors with embedded overcurrent protection. The inline mounted SPD eliminates connecting wire leads, propagation time delay response, and voltage drops due to wire inductance, providing accurate clamping level responses. The protecting assemblies are selected and coordinated to achieve a predefined response to react at protection threshold voltage levels and with current capacity to mitigate complex components of HEMP. The tertiary protection assembly disconnects an electrical load after a prolonged overvoltage is present associated with a Geomagnetic disturbance and reconnects the electrical load when an overvoltage condition is not present.
