Abstract: A system and method are disclosed for an electrical earthing or grounding system to protect electrical systems and structures. Such systems and structures are efficient at dissipating broadband energy. An earthing mix system in contact with a grounding electrode is separated into functional components; a conductive earthing mix which is in contact with an electrical conductor and an impedance transitioning earthing composition which is in contact with the conductivity earthing mix. The conductive earthing mix absorbs, radiates, conducts, and dissipates electrical energy. The impedance transitioning earthing mix acts as a lossy impedance matching media to reduce reflections and improve energy transfer. A conductive slurry mix fills in voids and aids in contact between the other elements.

Abstract: A method of installing an electrical grounding system at a site can comprise the steps of inserting a hollow electrode into a hole formed into native soil at the site, the hollow electrode comprising an electrically conductive tube configured for communication with a fault current source, and a carbon fiber layer in conductive relationship with at least a portion of the electrically conductive tube; positioning the hollow electrode in the hole circumferentially around a ground member driven into native soil at a bottom of the hole; and electrically interconnecting the ground member and the hollow electrode.

Abstract: An electrical grounding system can include an electrically conductive column configured for communication with a fault current source and a carbon fiber layer in conductive relationship with at least a portion of the electrically conductive column. The system can also include a salt replenishment tube configured for attachment to a ground member, the salt replenishment tube having a tube wall defining a weep hole. The system can further include electrolytic fill disposed within a column chamber at least partially-defined by the electrically-conductive column, the electrolytic fill comprising a material configured to conduct at least a portion of any fault current received by the ground member radially outwardly from the ground member. The system can further include a bus bar comprising electrically-interconnected bus bar connectors, wherein the bus bar electrically communicates with the electrically conductive column and with the fault current source.
