The power lost by conduction into copper, silver and tungsten cathodes surrounded by water-cooled brass was determined experimentally. The measurements were made for prolonged short arcs (0.4-1 mm)… Continue Reading
A theoretical model of a low-current electric arc at the anode is presented. This method is based on the numerical resolution of a closed system of equations which makes it possible to determine the… Continue Reading
A macroscopic model based on Mackeown's (for the electric field) and Murphy's theories (for electron current density) is used to calculate the characteristic parameters of the arc roots at… Continue Reading
L'etude des phenomenes se produisant au niveau des electrodes de nature differente soumises a un arc electrique a necessite l'elaboration d'un systeme d'equations theoriques moyennant quelques… Continue Reading
The mechanisms occurring at the anode of an electric arc are less important compared to that at the cathode, Many studies have been carried out to get a better understanding of anode phenomena in… Continue Reading
