Method and systems for electromagnetic protection with persistent self monitoring and cybersecure local and remote status report

A method for persistent monitoring, detecting, and protecting a monitored infrastructure from a high-altitude electromagnetic pulse (HEMP), mitigating the effects of the HEMP, and communicating in real time the status of the monitored infrastructure locally and remotely via a cybersecure channel so as to protect the monitored infrastructure, said method for monitoring, detecting, protecting, and communicating, comprising:

• a phase unit receiving sensor signals from a plurality of sensors electrically connected individually to each of a first phase, second phase, and third phase electrical line, respectively, upstream of and associated with the monitored infrastructure, said plurality of sensors generating amplitude and status data in real time and communicating said data via a cybersecure optical communication channel;
• and
• determining in real time if said sensor signals associated with said respective electrical line are indicative of an E1 component of the HEMP and, if so, actuating a mitigation response in less than 300 nanoseconds to electrically shunt, redirect, limit, and absorb an excess of surge energy on said respective electrical line to prevent propagation of hazardous electrical signals to the monitored infrastructure and, if not, continuing to monitor said sensor signals;
• and
• determining in real time if said sensor signals associated with said respective electrical line is indicative of an E2 and E3 component of the HEMP and, if so, actuating a mitigation response to electrically shunt, redirect, limit, and absorb an excess of surge energy on said respective electrical line to prevent propagation of hazardous electrical signals to the monitored infrastructure and, if not, continuing to monitor said sensor signals;
• determining in real time if said sensor signals associated with said respective electrical line are (1) indicative of electromagnetic fields associated with the E1 component of a HEMP while originating from intentional electromagnetic interference (IEMI) sources or are (2) indicative of electromagnetic fields associated with the E3 component of a HEMP while originating from Geomagnetic disturbance (GMD) and, if so, actuating a mitigation response to prevent propagation of hazardous electrical transient energy to the monitored infrastructure and, if not, continuing to monitor said sensor signals.
