A model of gas temperature decay after arc extinction of small air gaps

Abstract

A gas temperature decay model has been developed assuming that the recovering hot gas is a spherical lump and its temperature is uniform throughout the recovery. The calculation of the temperature decay by this model consists of the calculation of the time constants of the decay process of the recovering hot gas as a function of the size of the spherical gas lump and gas temperature. Calculated temperature decay characteristics almost agree with those obtained from experimental voltage-recovery characteristics.<>
