Abstract
A circuit includes a detector and controller circuit configured to detect a high field RF (radio frequency) electromagnetic fields indicating a potential of an electromagnetic pulse event capable of damaging electrical equipment connected to a power grid. The circuit also includes controller receiving an input from the detector circuit, the controller being included within a shielded enclosure and configured to initiate an event in response to detection of the high field electromagnetic pulse field to remove the electrical equipment from the power grid.
