The estimation of static breakdown voltage for gas-filled tubes at low pressures using dynamic method

The paper presents experimental data of breakdown voltage as a function of voltage increase rate for nitrogen-filled tubes at pressures of 133 and 399 Pa. By fitting this data using polynomial approximation, static breakdown voltages for these tubes were estimated. The influence of voltage increase rate, voltage step, time interval between successive voltage step, and relaxation time on the static breakdown voltage was analyzed. The processes in gas advanced during breakdown were also analyzed, as well as their influence on the breakdown voltage. Index Terms--Breakdown voltage, nitrogen, relaxation time, static breakdown voltage, surface recombination, voltage increase rate, voltage step.
