Abstract: A method and system may suppress EM-induced voltage surges due to transient electromagnetic energy disturbance such as a detonation of a nuclear weapon at high altitude generating an EMP (HEMP), intentional electromagnetic interference (IEMI), natural lightning strikes, a Geo-magnetic disturbance (GMD) produced by a coronal mass ejection (CME), or other transient surges due to radiated and conducted electromagnetic interference (EMI). The system may include embedded surge protection assemblies for inline installation on electric power and communication networks with electrical and electronic devices on electrical network, powered by AC and DC sources. The inline mounting of the embedded surge suppression system may eliminate any time delay response associated with long lead wires of across the lines surge protection installation.
