Static Characteristics of Defined Ignition Voltage Used in the Modelling of Arc within a Wide Range of Current Excitation

The article presents relatively extensive sets of selected functions useful for the approximation of voltage-current characteristics of static arc of defined and undefined ignition voltage values. The article contains graphs of the above-named functions presenting their effectiveness in the mathematical representation of arc within wide ranges of current excitation. Selected static characteristics were applied to the Pentegov mathematical model. The research also involved simulations of processes in circuits with models of arc having defined and undefined ignition voltage.
