| Popis: | Experimental study: - low current (2 - 5 A): Ag, Cu, W. - high current (100 - 2000 A): AgNi, AgWC, AgCdO, AgZnO, AgSnO2.; 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 atmospheric pressure in the whole range of current covering largely the experimental field (0.1 - 8500 A). A comparison between some theoretical and experimental electrode parameters is presented. |
