  • Series static spark gap for EMP protection
    Patent number: 11329480
    Abstract: A method for protecting an electrical transmission system having an electrical transmission line coupled to electrical equipment from hazardous EMI comprises receiving at least one pulse of hazardous EMI on the transmission line, and shunting current induced on the electrical transmission line by the at least one pulse of hazardous EMI to ground through at least one static series spark gap apparatus in such manner as to bypass high speed transient voltages from the electrical equipment to ground via a low impedance means and prevent damage thereto, wherein the static series spark gap apparatus has a rise time that is typically 2 nanoseconds or less.
