A system of surge suppressor units is connected at multiple locations on a power transmission and distribution grid to provide grid level protection against various disturbances before such disturbances can reach or affect facility level equipment. The surge suppressor units effectively prevent major voltage and current spikes from impacting the grid. In addition, the surge suppressor units include various integration features which provide diagnostic and remote reporting capabilities required by most utility operations. As such, the surge suppressor units protect grid level components from major events such as natural geomagnetic disturbances (solar flares), extreme electrical events (lightning) and human-generated events (EMPs) and cascading failures on the power grid.

A protection monitoring system is provided that includes a protection fault handler. The protection fault handler includes a protection fault indicator. The protection fault handler is configured to activate the protection fault indicator upon indication of a protection fault signal. Moreover, the protection fault signal is indicative of a critical fault which has occurred in a protection system monitored by the protection monitoring system. The protection monitoring system also includes a user inhibit handler. The user inhibit handler includes a user inhibit indicator. Moreover, the user inhibit handler is configured to activate the user inhibit indicator upon indication of a user inhibit signal. Furthermore, the user inhibit signal is indicative of a user-enabled alarm inhibit or a user-enabled bypass.

An apparatus detects complex time-variant electromagnetic disturbances resulting from a high-altitude nuclear electromagnetic pulse (EMP) or solar storm. The device relies on a circuit (104, 1301) to monitor the input power lines (301, 401, 501) for sustained conducted electrical disturbances associated with the E3 phase of an EMP or solar storm. A separate circuit (105, 1302) monitors the power lines and the ambient environment (503) for transient electromagnetic pulse disturbances associated with the E1 and E2 phases of an EMP. When sustained electrical disturbances or transient electromagnetic pulse disturbances are detected, the apparatus provides a visual alarm (603. 609), audible alarm (608), and discrete indication signal (607) that can be used to disconnect (702) or redirect the flow of electrical power.
