Influence of Current and Electrode Material on Fraction k of Electric Arc Energy Leading to Pressure Rise in a Closed Container During Internal Arcing

The fraction k_p of electric arc energy leading to pressure rise in its surroundings is determined in dependence on arc current and electrode material for an arc occurring in a closed container. It is shown that the k p values for closed containers depend apart from the electrode material on the lev...

Description
Summary:The fraction k_p of electric arc energy leading to pressure rise in its surroundings is determined in dependence on arc current and electrode material for an arc occurring in a closed container. It is shown that the k p values for closed containers depend apart from the electrode material on the level of arc current, which, in turn, affects the energy balance.
