Electrical Surge Arrestors ESAs have been used extensively for lightning and EMP protection. These components are characterized by a presenting an open circuit high impedance below the gap breakdown potential, b becoming a virtual short-circuit above the gap breakdown and c displaying a significantly higher level of apparent gap breakdown for very fast input voltage rise-times dvdt. This paper describes a mathematical model for a spark gap surge arrestor which has been used successfully to characterize ESA response to stimulus.
