Development of a physical 2-D model for arc quenching chamber of lightning protection multichamber systems

The multi-chamber systems (MCS) were recently proposed as a prospective lightning protection device. 2D-physical model of arc discharge in MCS discharge chamber was developed in order to perform tests of quenching efficiency for various chamber geometry. It was shown that in case of chamber configuration with hollow electrodes the backflow from electrodes appears at some time instance during the current pulse decay phase.
