Abstract
The breakdown characteristics of various gaps are measured with and without a surge arrester in the circuit. Changes in the spark gap breakdown characteristics were observed when tested with the arrester in parallel and when subjected to various impulse shapes. A circuit model for the configuration is derived from these experimental results. Analysis of a proposed model for the voltage-time characteristics of the spark gap is presented. Simulation of the circuit model was conducted using EMTP, and showed agreement with the test data
