Spark gap consists of two electrodes separated by the air or other gas. When the voltage applied between the electrodes exceeds the breakdown level, gas ionization rapidly decreases the electric resistance between the electrodes and the electric discharge occurs.
Spark gaps are widely used in the high voltage switches, ignition devices, radio transmitters and variety of other applications. Spark gap simulation may be effectively performed using QuickField software. QuickField Electrostatic analysis of the spark gap will display distribution of the electric field within the gap, and may help in the spark gap design.
